-Release 2.4-r555 (6 November 2017)
-----------------------------------
-
-As is planned, this release focuses on fine tuning the base algorithm. Notable
-changes include
-
- * Changed the mapping quality scale to match the scale of BWA-MEM. This makes
-   minimap2 and BWA-MEM achieve similar sensitivity-specificity balance on real
-   short-read data.
-
- * Improved the accuracy of splice alignment by modeling one additional base
-   close to the GT-AG signal. This model is used by default with `-x splice`.
-   For SIRV control data, however, it is recommended to add `--splice-flank=no`
-   to disable this feature as the SIRV splice signals are slightly different.
-
- * Tuned the parameters for Nanopore Direct RNA reads. The recommended command
-   line is `-axsplice -k14 -uf` (#46).
-
- * Fixed a segmentation fault when aligning PacBio reads (#47 and #48). This
-   bug is very rare but it affects all versions of minimap2. It is also
-   recommended to re-index reference genomes created with `map-pb`. For human,
-   two minimizers in an old index are wrong.
-
- * Changed option `-L` in sync with the final decision of hts-specs: a fake
-   CIGAR takes the form of `<readLen>S<refLen>N`. Note that `-L` only enables
-   future tools to recognize long CIGARs. It is not possible for older tools to
-   work with such alignments in BAM (#43 and #51).
-
- * Fixed a tiny issue whereby minimap2 may waste 8 bytes per candidate
-   alignment.
-
-The minimap2 technical note hosted at arXiv has also been updated to reflect
-recent changes.
-
-(2.4: 6 November 2017, r555)
-
-
-
-Release 2.3-r531 (22 October 2017)
-----------------------------------
-
-This release come with many improvements and bug fixes:
-
- * The **sr** preset now supports paired-end short-read alignment. Minimap2 is
-   3-4 times as fast as BWA-MEM, but is slightly less accurate on simulated
-   reads.
-
- * Meticulous improvements to assembly-to-assembly alignment (special thanks to
-   Alexey Gurevich from the QUAST team): a) apply a small penalty to matches
-   between ambiguous bases; b) reduce missing alignments due to spurious
-   overlaps; c) introduce the short form of the `cs` tag, an improvement to the
-   SAM MD tag.
-
- * Make sure gaps are always left-aligned.
-
- * Recognize `U` bases from Oxford Nanopore Direct RNA-seq (#33).
-
- * Fixed slightly wrong chaining score. Fixed slightly inaccurate coordinates
-   for split alignment.
-
- * Fixed multiple reported bugs: 1) wrong reference name for inversion
-   alignment (#30); 2) redundant SQ lines when multiple query files are
-   specified (#39); 3) non-functioning option `-K` (#36).
-
-This release has implemented all the major features I planned five months ago,
-with the addition of spliced long-read alignment. The next couple of releases
-will focus on fine tuning of the base algorithms.
-
-(2.3: 22 October 2017, r531)
-
-
-
-Release 2.2-r409 (17 September 2017)
-------------------------------------
-
-This is a feature release. It improves single-end short-read alignment and
-comes with Python bindings. Detailed changes include:
-
- * Added the **sr** preset for single-end short-read alignment. In this mode,
-   minimap2 runs faster than BWA-MEM, but is slightly less accurate on
-   simulated data sets. Paired-end alignment is not supported as of now.
-
- * Improved mapping quality estimate with more accurate identification of
-   repetitive hits. This mainly helps short-read alignment.
-
- * Implemented **mappy**, a Python binding for minimap2, which is available
-   from PyPI and can be installed with `pip install --user mappy`. Python users
-   can perform read alignment without the minimap2 executable.
-
- * Restructured the indexing APIs and documented key minimap2 APIs in the
-   header file minimap.h. Updated example.c with the new APIs. Old APIs still
-   work but may become deprecated in future.
-
-This release may output alignments different from the previous version, though
-the overall alignment statistics, such as the number of aligned bases and long
-gaps, remain close.
-
-(2.2: 17 September 2017, r409)
-
-
-
-Release 2.1.1-r341 (6 September 2017)
--------------------------------------
-
-This is a maintenance release that is expected to output identical alignment to
-v2.1. Detailed changes include:
-
- * Support CPU dispatch. By default, minimap2 is compiled with both SSE2 and
-   SSE4 based implementation of alignment and automatically chooses the right
-   one at runtime. This avoids unexpected errors on older CPUs (#21).
-
- * Improved Windows support as is requested by Oxford Nanopore (#19). Minimap2
-   now avoids variable-length stacked arrays, eliminates alloca(), ships with
-   getopt_long() and provides timing functions implemented with Windows APIs.
-
- * Fixed a potential segmentation fault when specifying -k/-w/-H with
-   multi-part index (#23).
-
- * Fixed two memory leaks in example.c
-
-(2.1.1: 6 September 2017, r341)
-
-
-
-Release 2.1-r311 (25 August 2017)
----------------------------------
-
-This release adds spliced alignment for long noisy RNA-seq reads. On a SMRT
-Iso-Seq and a Oxford Nanopore data sets, minimap2 appears to outperform
-traditional mRNA aligners. For DNA alignment, this release gives almost
-identical output to v2.0. Other changes include:
-
- * Added option `-R` to set the read group header line in SAM.
-
- * Optionally output the `cs:Z` tag in PAF to encode both the query and the
-   reference sequences in the alignment.
-
- * Fixed an issue where DP alignment uses excessive memory.
-
-The minimap2 technical report has been updated with more details and the
-evaluation of spliced alignment:
-
- * Li, H. (2017). Minimap2: fast pairwise alignment for long nucleotide
-   sequences. [arXiv:1708.01492v2](https://arxiv.org/abs/1708.01492v2).

-
-
-Release 2.0-r275 (8 August 2017)
---------------------------------
-
-This release is identical to version 2.0rc1, except the version number. It is
-described and evaluated in the following technical report:
-
- * Li, H. (2017). Minimap2: fast pairwise alignment for long DNA sequences.
-   [arXiv:1708.01492v1](https://arxiv.org/abs/1708.01492v1).
-
-(2.0: 8 August 2017, r275)
-
-
-
-Release 2.0rc1-r232 (30 July 2017)
-----------------------------------
-
-This release improves the accuracy of long-read alignment and added several
-minor features.
-
- * Improved mapping quality estimate for short alignments containing few seed
-   hits.
-
- * Fixed a minor bug that affects the chaining accuracy towards the ends of a
-   chain. Changed the gap cost for chaining to reduce false seeding.
-
- * Skip potentially wrong seeding and apply dynamic programming more frequently.
-   This slightly increases run time, but greatly reduces false long gaps.
-
- * Perform local alignment at Z-drop break point to recover potential inversion
-   alignment. Output the SA tag in the SAM format. Added scripts to evaluate
-   mapping accuracy for reads simulated with pbsim.
-
-This release completes features intended for v2.0. No major features will be
-added to the master branch before the final v2.0.
-
-(2.0rc1: 30 July 2017, r232)
-
-
-
-Release r191 (19 July 2017)
----------------------------
-
-This is the first public release of minimap2, an aligner for long reads and
-assemblies. This release has a few issues and is generally not recommended for
-production uses.

-## <a name="uguide"></a>Users' Guide
-
-Minimap2 is a versatile sequence alignment program that aligns DNA or mRNA
-sequences against a large reference database. Typical use cases include: (1)
-mapping PacBio or Oxford Nanopore genomic reads to the human genome; (2)
-finding overlaps between long reads with error rate up to ~15%; (3)
-splice-aware alignment of PacBio Iso-Seq or Nanopore cDNA or Direct RNA reads
-against a reference genome; (4) aligning Illumina single- or paired-end reads;
-(5) assembly-to-assembly alignment; (6) full-genome alignment between two
-closely related species with divergence below ~15%.
-
-For ~10kb noisy reads sequences, minimap2 is tens of times faster than
-mainstream long-read mappers such as BLASR, BWA-MEM, NGMLR and GMAP. It is more
-accurate on simulated long reads and produces biologically meaningful alignment
-ready for downstream analyses. For >100bp Illumina short reads, minimap2 is
-three times as fast as BWA-MEM and Bowtie2, and as accurate on simulated data.
-Detailed evaluations are available from the [minimap2 preprint][preprint].
-
-### <a name="install"></a>Installation
-
-Minimap2 only works on x86-64 CPUs. You can acquire precompiled binaries from
-the [release page][release] with:
-```sh
-wget --no-check-certificate -O- https://github.com/lh3/minimap2/releases/download/v2.4/minimap2-2.4_x64-linux.tar.bz2 \
-  | tar -jxvf -
-./minimap2-2.4_x64-linux/minimap2
-```
-If you want to compile from the source, you need to have a C compiler, GNU make
-and zlib development files installed. Then type `make` in the source code
-directory to compile. If you see compilation errors, try `make sse2only=1`
-to disable SSE4 code, which will make minimap2 slightly slower.
-
-### <a name="general"></a>General usage
-
-Without any options, minimap2 takes a reference database and a query sequence
-file as input and produce approximate mapping, without base-level alignment
-(i.e. no CIGAR), in the [PAF format][paf]:
-```sh
-minimap2 ref.fa query.fq > approx-mapping.paf
-```
-You can ask minimap2 to generate CIGAR at the `cg` tag of PAF with:
-```sh
-minimap2 -c ref.fa query.fq > alignment.paf
-```
-or to output alignments in the [SAM format][sam]:
-```sh
-minimap2 -a ref.fa query.fq > alignment.sam
-```
-Minimap2 seamlessly works with gzip'd FASTA and FASTQ formats as input. You
-don't need to convert between FASTA and FASTQ or decompress gzip'd files first.
-
-For the human reference genome, minimap2 takes a few minutes to generate a
-minimizer index for the reference before mapping. To reduce indexing time, you
-can optionally save the index with option **-d** and replace the reference
-sequence file with the index file on the minimap2 command line:
-```sh
-minimap2 -d ref.mmi ref.fa                     # indexing
-minimap2 -a ref.mmi reads.fq > alignment.sam   # alignment
-```
-***Importantly***, it should be noted that once you build the index, indexing
-parameters such as **-k**, **-w**, **-H** and **-I** can't be changed during
-mapping. If you are running minimap2 for different data types, you will
-probably need to keep multiple indexes generated with different parameters.
-This makes minimap2 different from BWA which always uses the same index
-regardless of query data types.
-
-### <a name="cases"></a>Use cases
-
-Minimap2 uses the same base algorithm for all applications. However, due to the
-different data types it supports (e.g. short vs long reads; DNA vs mRNA reads),
-minimap2 needs to be tuned for optimal performance and accuracy. It is usually
-recommended to choose a preset with option **-x**, which sets multiple
-parameters at the same time. The default setting is the same as `map-ont`.
-
-#### <a name="map-long-genomic"></a>Map long noisy genomic reads
-
-```sh
-minimap2 -ax map-pb  ref.fa pacbio-reads.fq > aln.sam   # for PacBio subreads
-minimap2 -ax map-ont ref.fa ont-reads.fq > aln.sam      # for Oxford Nanopore reads
-```
-The difference between `map-pb` and `map-ont` is that `map-pb` uses
-homopolymer-compressed (HPC) minimizers as seeds, while `map-ont` uses ordinary
-minimizers as seeds. Emperical evaluation suggests HPC minimizers improve
-performance and sensitivity when aligning PacBio reads, but hurt when aligning
-Nanopore reads.
-
-#### <a name="map-long-splice"></a>Map long mRNA/cDNA reads
-
-```sh
-minimap2 -ax splice -uf ref.fa iso-seq.fq > aln.sam          # PacBio Iso-seq/traditional cDNA
-minimap2 -ax splice ref.fa nanopore-cdna.fa > aln.sam        # Nanopore 2D cDNA-seq
-minimap2 -ax splice -uf -k14 ref.fa direct-rna.fq > aln.sam  # Nanopore Direct RNA-seq
-minimap2 -ax splice --splice-flank=no SIRV.fa SIRV-seq.fa    # mapping against SIRV control
-```
-There are different long-read RNA-seq technologies, including tranditional
-full-length cDNA, EST, PacBio Iso-seq, Nanopore 2D cDNA-seq and Direct RNA-seq.
-They produce data of varying quality and properties. By default, `-x splice`
-assumes the read orientation relative to the transcript strand is unknown. It
-tries two rounds of alignment to infer the orientation and write the strand to
-the `ts` SAM/PAF tag if possible. For Iso-seq, Direct RNA-seq and tranditional
-full-length cDNAs, it would be desired to apply `-u f` to force minimap2 to
-consider the forward transcript strand only. This speeds up alignment with
-slight improvement to accuracy. For noisy Nanopore Direct RNA-seq reads, it is
-recommended to use a smaller k-mer size for increased sensitivity to the first
-or the last exons.
-
-It is worth noting that by default `-x splice` prefers GT[A/G]..[C/T]AG
-over GT[C/T]..[A/G]AG, and then over other splicing signals. Considering
-one additional base improves the junction accuracy for noisy reads, but
-reduces the accuracy when aligning against the widely used SIRV control data.
-This is because SIRV does not honor the evolutionarily conservative splicing
-signal. If you are studying SIRV, you may apply `--splice-flank=no` to let
-minimap2 only model GT..AG, ignoring the additional base.
-
-#### <a name="long-overlap"></a>Find overlaps between long reads
-
-```sh
-minimap2 -x ava-pb  reads.fq reads.fq > ovlp.paf    # PacBio read overlap
-minimap2 -x ava-ont reads.fq reads.fq > ovlp.paf    # Oxford Nanopore read overlap
-```
-Similarly, `ava-pb` uses HPC minimizers while `ava-ont` uses ordinary
-minimizers. It is usually not recommended to perform base-level alignment in
-the overlapping mode because it is slow and may produce false positive
-overlaps. However, if performance is not a concern, you may try to add `-a` or
-`-c` anyway.
-
-#### <a name="short-genomic"></a>Map short accurate genomic reads
-
-```sh

-```
-When two read files are specified, minimap2 reads from each file in turn and
-merge them into an interleaved stream internally. Two reads are considered to
-be paired if they are adjacent in the input stream and have the same name (with
-the `/[0-9]` suffix trimmed if present). Single- and paired-end reads can be
-mixed.
-
-Minimap2 does not work well with short spliced reads. There are many capable
-RNA-seq mappers for short reads.

-
-```sh
-minimap2 -ax asm5 ref.fa asm.fa > aln.sam       # assembly to assembly/ref alignment
-```
-For cross-species full-genome alignment, the scoring system needs to be tuned
-according to the sequence divergence.

-
-#### <a name="long-cigar"></a>Working with >65535 CIGAR operations
-
-Due to a design flaw, BAM does not work with CIGAR strings with >65535
-operations (SAM and CRAM work). However, for ultra-long nanopore reads minimap2
-may align ~1% of read bases with long CIGARs beyond the capability of BAM. If
-you convert such SAM/CRAM to BAM, Picard and recent samtools will throw an
-error and abort. Older samtools and other tools may create corrupted BAM.
-
-To avoid this issue, you can add option `-L` at the minimap2 command line.
-This option moves a long CIGAR to the `CG` tag and leaves a fully clipped CIGAR
-at the SAM CIGAR column. Current tools that don't read CIGAR (e.g. merging and
-sorting) still work with such BAM records; tools that read CIGAR will
-effectively ignore these records. It has been decided that future tools will
-will seamlessly recognize long-cigar records generated by option `-L`.
-
-**TD;DR**: if you work with ultra-long reads and use tools that only process
-BAM files, please add option `-L`.
-
-#### <a name="cs"></a>The cs optional tag
-
-The `cs` SAM/PAF tag encodes bases at mismatches and INDELs. It matches regular
-expression `/(:[0-9]+|\*[a-z][a-z]|[=\+\-][A-Za-z]+)+/`. Like CIGAR, `cs`
-consists of series of operations.  Each leading character specifies the
-operation; the following sequence is the one involved in the operation.
-
-The `cs` tag is enabled by command line option `--cs`. The following alignment,
-for example:
-```txt
-CGATCGATAAATAGAGTAG---GAATAGCA
-||||||   ||||||||||   |||| |||
-CGATCG---AATAGAGTAGGTCGAATtGCA
-```
-is represented as `:6-ata:10+gtc:4*at:3`, where `:[0-9]+` represents an
-identical block, `-ata` represents a deltion, `+gtc` an insertion and `*at`
-indicates reference base `a` is substituted with a query base `t`. It is
-similar to the `MD` SAM tag but is standalone and easier to parse.
-
-If `--cs=long` is used, the `cs` string also contains identical sequences in
-the alignment. The above example will become
-`=CGATCG-ata=AATAGAGTAG+gtc=GAAT*at=GCA`. The long form of `cs` encodes both
-reference and query sequences in one string.
-
-#### <a name="eval"></a>Evaluation scripts
-
-Minimap2 comes with several (java)scripts for evaluating the accuracy of
-minimap2. These scripts require the [k8][k8] javascript shell to run.
-Recent minimap2 binary release tar-balls contain a copy of k8 executable, a
-single file. Here are a few examples on how to use these scripts:
-
-```sh
-# Generate reads from PBSIM alignment (truth encoded in read names)
-k8 misc/sim-pbsim.js ref.fa.fai pbsim-aln.maf > pbsim-reads.fq
-# Generate reads from mason2 alignment (not tested for simulated SVs)
-k8 misc/sim-mason2.js mason2-aln.sam > mason2-reads.fq
-# Evaluate mapping accuracy with ROC-like curve
-k8 misc/sim-eval.js my-aln.sam.gz > result.txt
-k8 misc/sim-eval.js my-aln.paf.gz > result.txt
-# Collect alignment statistics
-k8 misc/mapstat.js my-aln.sam > result.txt
-# Compare spliced junctions to existing gene annotations
-k8 misc/intron-eval.js anno.gtf my-spliced-aln.sam > result.txt
-```

-### <a name="algo"></a>Algorithm overview
-
-In the following, minimap2 command line options have a dash ahead and are
-highlighted in bold. The description may help to tune minimap2 parameters.
-
-1. Read **-I** [=*4G*] reference bases, extract (**-k**,**-w**)-minimizers and
-   index them in a hash table.
-
-2. Read **-K** [=*200M*] query bases. For each query sequence, do step 3
-   through 7:
-
-3. For each (**-k**,**-w**)-minimizer on the query, check against the reference
-   index. If a reference minimizer is not among the top **-f** [=*2e-4*] most
-   frequent, collect its the occurrences in the reference, which are called
-   *seeds*.
-
-4. Sort seeds by position in the reference. Chain them with dynamic
-   programming. Each chain represents a potential mapping. For read
-   overlapping, report all chains and then go to step 8. For reference mapping,
-   do step 5 through 7:
-
-5. Let *P* be the set of primary mappings, which is an empty set initially. For
-   each chain from the best to the worst according to their chaining scores: if
-   on the query, the chain overlaps with a chain in *P* by **--mask-level**
-   [=*0.5*] or higher fraction of the shorter chain, mark the chain as
-   *secondary* to the chain in *P*; otherwise, add the chain to *P*.
-
-6. Retain all primary mappings. Also retain up to **-N** [=*5*] top secondary
-   mappings if their chaining scores are higher than **-p** [=*0.8*] of their
-   corresponding primary mappings.
-
-7. If alignment is requested, filter out an internal seed if it potentially
-   leads to both a long insertion and a long deletion. Extend from the
-   left-most seed. Perform global alignments between internal seeds.  Split the
-   chain if the accumulative score along the global alignment drops by **-z**
-   [=*400*], disregarding long gaps. Extend from the right-most seed.  Output
-   chains and their alignments.
-
-8. If there are more query sequences in the input, go to step 2 until no more
-   queries are left.
-
-9. If there are more reference sequences, reopen the query file from the start
-   and go to step 1; otherwise stop.

-### <a name="help"></a>Getting help
-
-Manpage [minimap2.1](minimap2.1) provides detailed description of minimap2
-command line options and optional tags. If you encounter bugs or have further
-questions or requests, you can raise an issue at the [issue page][issue].
-There is not a specific mailing list for the time being.
-
-### <a name="cite"></a>Citing minimap2
-
-If you use minimap2 in your work, please consider to cite:

-
-## <a name="dguide"></a>Developers' Guide
-
-Minimap2 is not only a command line tool, but also a programming library.
-It provides C APIs to build/load index and to align sequences against the
-index. File [example.c](example.c) demonstrates typical uses of C APIs. Header
-file [minimap.h](minimap.h) gives more detailed API documentation. Minimap2
-aims to keep APIs in this header stable. File [mmpriv.h](mmpriv.h) contains
-additional private APIs which may be subjected to changes frequently.
-
-This repository also provides Python bindings to a subset of C APIs. File
-[python/README.rst](python/README.rst) gives the full documentation;
-[python/minimap2.py](python/minimap2.py) shows an example. This Python
-extension, mappy, is also [available from PyPI][mappypypi] via `pip install
-mappy` or [from BioConda][mappyconda] via `conda install -c bioconda mappy`.
-
-## <a name="limit"></a>Limitations
-
-* Minimap2 may produce suboptimal alignments through long low-complexity
-  regions where seed positions may be suboptimal. This should not be a big
-  concern because even the optimal alignment may be wrong in such regions.
-
-* Minimap2 requires SSE2 instructions to compile. It is possible to add
-  non-SSE2 support, but it would make minimap2 slower by several times.
-
-In general, minimap2 is a young project with most code written since June, 2017.
-It may have bugs and room for improvements. Bug reports and suggestions are
-warmly welcomed.

-  2013-05-02 (0.2.8):
-
-	* Use quadratic probing. When the capacity is power of 2, stepping function
-	  i*(i+1)/2 guarantees to traverse each bucket. It is better than double
-	  hashing on cache performance and is more robust than linear probing.
-
-	  In theory, double hashing should be more robust than quadratic probing.
-	  However, my implementation is probably not for large hash tables, because
-	  the second hash function is closely tied to the first hash function,
-	  which reduce the effectiveness of double hashing.
-
-	Reference: http://research.cs.vt.edu/AVresearch/hashing/quadratic.php
-
-  2011-12-29 (0.2.7):
-
-    * Minor code clean up; no actual effect.
-
-  2011-09-16 (0.2.6):
-
-	* The capacity is a power of 2. This seems to dramatically improve the
-	  speed for simple keys. Thank Zilong Tan for the suggestion. Reference:
-
-	   - http://code.google.com/p/ulib/
-	   - http://nothings.org/computer/judy/
-
-	* Allow to optionally use linear probing which usually has better
-	  performance for random input. Double hashing is still the default as it
-	  is more robust to certain non-random input.
-
-	* Added Wang's integer hash function (not used by default). This hash
-	  function is more robust to certain non-random input.
-
-  2011-02-14 (0.2.5):
-
-    * Allow to declare global functions.
-
-  2009-09-26 (0.2.4):
-
-    * Improve portability
-
-  2008-09-19 (0.2.3):
-
-	* Corrected the example
-	* Improved interfaces
-
-  2008-09-11 (0.2.2):
-
-	* Improved speed a little in kh_put()
-
-  2008-09-10 (0.2.1):
-
-	* Added kh_clear()
-	* Fixed a compiling error
-
-  2008-09-02 (0.2.0):
-
-	* Changed to token concatenation which increases flexibility.
-
-  2008-08-31 (0.1.2):
-
-	* Fixed a bug in kh_get(), which has not been tested previously.

-  2008-08-31 (0.1.1):

-.SH DESCRIPTION
-.PP
-Minimap2 is a fast sequence mapping and alignment program that can find
-overlaps between long noisy reads, or map long reads or their assemblies to a
-reference genome optionally with detailed alignment (i.e. CIGAR). At present,
-it works efficiently with query sequences from a few kilobases to ~100
-megabases in length at a error rate ~15%. Minimap2 outputs in the PAF or the
-SAM format.
-.SH OPTIONS
-.SS Indexing options
-.TP 10
-.BI -k \ INT
-Minimizer k-mer length [15]
-.TP
-.BI -w \ INT
-Minimizer window size [2/3 of k-mer length]. A minimizer is the smallest k-mer
-in a window of w consecutive k-mers.
-.TP
-.B -H
-Use homopolymer-compressed (HPC) minimizers. An HPC sequence is constructed by
-contracting homopolymer runs to a single base. An HPC minimizer is a minimizer
-on the HPC sequence.
-.TP
-.BI -I \ NUM
-Load at most
-.I NUM
-target bases into RAM for indexing [4G]. If there are more than
-.I NUM
-bases in
-.IR target.fa ,
-minimap2 needs to read
-.I query.fa
-multiple times to map it against each batch of target sequences.
-.I NUM
-may be ending with k/K/m/M/g/G. NB: mapping quality is incorrect given a
-multi-part index.
-.TP
-.BI -d \ FILE
-Save the minimizer index of
-.I target.fa
-to
-.I FILE
-[no dump]. Minimap2 indexing is fast. It can index the human genome in a couple
-of minutes. If even shorter startup time is desired, use this option to save
-the index. Indexing options are fixed in the index file. When an index file is
-provided as the target sequences, options
-.BR -H ,
-.BR -k ,
-.BR -w ,
-.B -I
-will be effectively overridden by the options stored in the index file.
-.SS Mapping options
-.TP 10
-.BI -f \ FLOAT
-Ignore top
-.I FLOAT
-fraction of most frequent minimizers [0.0002]
-.TP
-.BI -g \ INT
-Stop chain enlongation if there are no minimizers in
-.IR INT -bp
-[10000].
-.TP
-.BI -r \ INT
-Bandwidth used in chaining and DP-based alignment [500]. This option
-approximately controls the maximum gap size.
-.TP
-.BI -n \ INT
-Discard chains consisting of
-.RI < INT
-number of minimizers [3]
-.TP
-.BI -m \ INT
-Discard chains with chaining score
-.RI < INT
-[40]. Chaining score equals the approximate number of matching bases minus a
-concave gap penalty. It is computed with dynamic programming.
-.TP
-.B -X
-Perform all-vs-all mapping. In this mode, if the query sequence name is
-lexicographically larger than the target sequence name, the hits between them
-will be suppressed; if the query sequence name is the same as the target name,
-diagonal minimizer hits will also be suppressed.
-.TP
-.BI -p \ FLOAT
-Minimal secondary-to-primary score ratio to output secondary mappings [0.8].
-Between two chains overlaping over half of the shorter chain (controlled by
-.BR --mask-level ),
-the chain with a lower score is secondary to the chain with a higher score.
-If the ratio of the scores is below
-.IR FLOAT ,
-the secondary chain will not be outputted or extended with DP alignment later.
-.TP
-.BI -N \ INT
-Output at most
-.I INT
-secondary alignments [5]. This option has no effect when
-.B -X
-is applied.
-.TP
-.BI -G \ NUM
-Maximum gap on the reference (effective with
-.BR -xsplice / --splice ).
-This option also changes the chaining and alignment band width to
-.IR NUM .
-Increasing this option slows down spliced alignment. [200k]
-.TP
-.BI -F \ NUM
-Maximum fragment length (aka insert size; effective with
-.BR -xsr / --frag)
-[800]
-.TP
-.BI --max-chain-skip \ INT
-A heuristics that stops chaining early [50]. Minimap2 uses dynamic programming
-for chaining. The time complexity is quadratic in the number of seeds. This
-option makes minimap2 exits the inner loop if it repeatedly sees seeds already
-on chains. Set
-.I INT
-to a large number to switch off this heurstics.
-.TP
-.B --no-long-join
-Disable the long gap patching heuristic. When this option is applied, the
-maximum alignment gap is mostly controlled by
-.BR -r .
-.TP
-.B --splice
-Enable the splice alignment mode.
-.TP
-.B --sr
-Enable short-read alignment heuristics. In the short-read mode, minimap2
-applies a second round of chaining with a higher minimizer occurrence threshold
-if no good chain is found. In addition, minimap2 attempts to patch gaps between
-seeds with ungapped alignment.
-.TP
-.BR --frag [= no | yes ]
-Whether to enable the fragment mode [no]
-.SS Alignment options
-.TP 10
-.BI -A \ INT
-Matching score [2]
-.TP
-.BI -B \ INT
-Mismatching penalty [4]
-.TP
-.BI -O \ INT1[,INT2]
-Gap open penalty [4,24]. If
-.I INT2
-is not specified, it is set to
-.IR INT1 .
-.TP
-.BI -E \ INT1[,INT2]
-Gap extension penalty [2,1]. A gap of length
-.I k
-costs
-.RI min{ O1 + k * E1 , O2 + k * E2 }.
-In the splice mode, the second gap penalties are not used.
-.TP
-.BI -C \ INT
-Cost for a non-canonical GT-AG splicing (effective with
-.BR --splice )
-[0]
-.TP
-.BI -z \ INT
-Break an alignment if the running score drops too quickly along the diagonal of
-the DP matrix (diagonal X-drop, or Z-drop) [400]. Increasing the value improves
-the contiguity of the alignment at the cost of poor alignment in the middle
-(e.g. caused by a long inversion).
-.TP
-.BI -s \ INT
-Minimal peak DP alignment score to output [40]. The peak score is computed from
-the final CIGAR. It is the score of the max scoring segment in the alignment
-and may be different from the total alignment score.
-.TP
-.BI -u \ CHAR
-How to find canonical splicing sites GT-AG -
-.BR f :
-transcript strand;
-.BR b :
-both strands;
-.BR n :
-no attempt to match GT-AG [n]
-.TP
-.BI --end-bonus \ INT
-Score bonus when alignment extends to the end of the query sequence [0].
-.TP
-.BR --splice-flank [= yes | no ]
-Assume the next base to a
-.B GT
-donor site tends to be A/G (91% in human and 92% in mouse) and the preceding
-base to a
-.B AG
-acceptor tends to be C/T [yes with
-.BR --splice ].
-This trend is evolutionarily conservative, all the way to S. cerevisiae
-(PMID:18688272). Specifying this option generally leads to higher junction
-accuracy by several percents, so it is applied by default with
-.BR --splice .
-However, the SIRV control does not honor this trend
-(only ~60%). This option reduces accuracy. If you are benchmarking minimap2
-on SIRV data, please add
-.B --splice-flank=no
-to the command line.
-.SS Input/output options
-.TP 10
-.B -a
-Generate CIGAR and output alignments in the SAM format. Minimap2 outputs in PAF
-by default.
-.TP
-.B -Q
-Ignore base quality in the input file.
-.TP
-.B -L
-Write CIGAR with >65535 operators at the CG tag. Older tools are unable to
-convert alignments with >65535 CIGAR ops to BAM. This option makes minimap2 SAM
-compatible with older tools. Newer tools recognizes this tag and reconstruct
-the real CIGAR in memory.
-.TP
-.BI -R \ STR
-SAM read group line in a format like
-.B @RG\\\\tID:foo\\\\tSM:bar
-[].
-.TP
-.B -c
-Generate CIGAR. In PAF, the CIGAR is written to the `cg' custom tag.
-.TP
-.BI --cs[= STR ]
-Output the
-.B cs
-tag.
-.I STR
-can be either
-.I short
-or
-.IR long .
-If no
-.I STR
-is given,
-.I short
-is assumed. [none]
-.TP
-.BI --seed \ INT
-Integer seed for randomizing equally best hits. Minimap2 hashes
-.I INT
-and read name when choosing between equally best hits. [11]
-.TP
-.BI -t \ INT
-Number of threads [3]. Minimap2 uses at most three threads when indexing target
-sequences, and uses up to
-.IR INT +1
-threads when mapping (the extra thread is for I/O, which is frequently idle and
-takes little CPU time).
-.TP
-.B -2
-Use two I/O threads during mapping. By default, minimap2 uses one I/O thread.
-When I/O is slow (e.g. piping to gzip, or reading from a slow pipe), the I/O
-thread may become the bottleneck. Apply this option to use one thread for input
-and another thread for output, at the cost of increased peak RAM.
-.TP
-.BI -K \ NUM
-Number of bases loaded into memory to process in a mini-batch [500M].
-Similar to option
-.BR -I ,
-K/M/G/k/m/g suffix is accepted. A large
-.I NUM
-helps load balancing in the multi-threading mode, at the cost of increased
-memory.
-.TP
-.BR --secondary [= yes | no ]
-Whether to output secondary alignments [yes]
-.TP
-.B --version
-Print version number to stdout
-.SS Preset options
-.TP 10
-.BI -x \ STR
-Preset []. This option applies multiple options at the same time. It should be
-applied before other options because options applied later will overwrite the
-values set by
-.BR -x .
-Available
-.I STR
-are:
-.RS
-.TP 8
-.B map-pb
-PacBio/Oxford Nanopore read to reference mapping
-.RB ( -Hk19 )
-.TP
-.B map-ont
-Slightly more sensitive for Oxford Nanopore to reference mapping
-.RB ( -k15 ).
-For PacBio reads, HPC minimizers consistently leads to faster performance and
-more sensitive results in comparison to normal minimizers. For Oxford Nanopore
-data, normal minimizers are better, though not much. The effectiveness of HPC
-is determined by the sequencing error mode.
-.TP
-.B asm5
-Long assembly to reference mapping
-.RB ( -k19
-.B -w19 -A1 -B19 -O39,81 -E3,1 -s200
-.BR -z200 ).
-Typically, the alignment will not extend to regions with 5% or higher sequence
-divergence. Only use this preset if the average divergence is far below 5%.
-.TP
-.B asm10
-Long assembly to reference mapping
-.RB ( -k19
-.B -w19 -A1 -B9 -O16,41 -E2,1 -s200
-.BR -z200 ).
-Up to 10% sequence divergence.

-.B ava-pb
-PacBio all-vs-all overlap mapping
-.RB ( -Hk19
-.B -w5 -Xp0 -m100 -g10000 --max-chain-skip
-.BR 25 ).
-.TP
-.B ava-ont
-Oxford Nanopore all-vs-all overlap mapping
-.RB ( -k15
-.B -w5 -Xp0 -m100 -g10000 --max-chain-skip
-.BR 25 ).
-Similarly, the major difference from
-.B ava-pb
-is that this preset is not using HPC minimizers.
-.TP
-.B splice
-Long-read spliced alignment
-.RB ( -k15
-.B -w5 --splice -g2000 -G200k -A1 -B2 -O2,32 -E1,0 -C9 -z200 -ub
-.BR --splice-flank=yes ).
-In the splice mode, 1) long deletions are taken as introns and represented as
-the
-.RB ` N '
-CIGAR operator; 2) long insertions are disabled; 3) deletion and insertion gap
-costs are different during chaining; 4) the computation of the
-.RB ` ms '
-tag ignores introns to demote hits to pseudogenes.
-.TP
-.B sr
-Short single-end reads without splicing
-.RB ( -k21
-.B -w11 --sr --frag -A2 -B8 -O12,32 -E2,1 -r50 -p.5 -N20 -f1000,5000 -n2 -m20
-.B -s40 -g200 -2K50m
-.BR --secondary=no ).
-.RE
-.SS Miscellaneous options
-.TP 10
-.B --no-kalloc
-Use the libc default allocator instead of the kalloc thread-local allocator.
-This debugging option is mostly used with Valgrind to detect invalid memory
-accesses. Minimap2 runs slower with this option, especially in the
-multi-threading mode.
-.TP
-.B --print-qname
-Print query names to stderr, mostly to see which query is crashing minimap2.
-.TP
-.B --print-seeds
-Print seed positions to stderr, for debugging only.
-.SH OUTPUT FORMAT
-.PP
-Minimap2 outputs mapping positions in the Pairwise mApping Format (PAF) by
-default. PAF is a TAB-delimited text format with each line consisting of at
-least 12 fields as are described in the following table:
-.TS
-center box;
-cb | cb | cb
-r | c | l .
-Col	Type	Description
-_
-1	string	Query sequence name
-2	int	Query sequence length
-3	int	Query start coordinate (0-based)

-.PP
-When alignment is available, column 11 gives the total number of sequence
-matches, mismatches and gaps in the alignment; column 10 divided by column 11
-gives the BLAST-like alignment identity. When alignment is unavailable,
-these two columns are approximate. PAF may optionally have additional fields in
-the SAM-like typed key-value format. Minimap2 may output the following tags:
-.TS
-center box;
-cb | cb | cb
-r | c | l .
-Tag	Type	Description
-_
-tp	A	Type of aln: P/primary, S/secondary and I/inversion
-cm	i	Number of minimizers on the chain

-s2	i	Chaining score of the best secondary chain
-NM	i	Total number of mismatches and gaps in the alignment
-AS	i	DP alignment score
-ms	i	DP score of the max scoring segment in the alignment
-nn	i	Number of ambiguous bases in the alignment
-ts	A	Transcript strand (splice mode only)
-cg	Z	CIGAR string (only in PAF)
-cs	Z	Difference string
-.TE
-
-.PP
-The
-.B cs
-tag encodes difference sequences in the short form or the entire query
-.I AND
-reference sequences in the long form. It consists of a series of operations:

-.SH LIMITATIONS
-.TP 2
-*
-Minimap2 may produce suboptimal alignments through long low-complexity regions
-where seed positions may be suboptimal. This should not be a big concern

-==============================
-Mappy: Minimap2 Python Binding
-==============================
-
-Mappy provides a convenient interface to `minimap2
-<https://github.com/lh3/minimap2>`_, a fast and accurate C program to align
-genomic and transcribe nucleotide sequences.
-
-Installation
-------------
-
-Mappy depends on `zlib <http://zlib.net>`_. It can be installed with `pip
-<https://en.wikipedia.org/wiki/Pip_(package_manager)>`_:
-
-.. code:: shell
-
-	pip install --user mappy
-
-or from the minimap2 github repo (`Cython <http://cython.org>`_ required):
-
-.. code:: shell
-
-	git clone https://github.com/lh3/minimap2
-	cd minimap2
-	python setup.py install
-
-Usage
------
-
-The following Python script demonstrates the key functionality of mappy:
-
-.. code:: python
-
-	import mappy as mp
-	a = mp.Aligner("test/MT-human.fa")  # load or build index
-	if not a: raise Exception("ERROR: failed to load/build index")
-	for name, seq, qual in mp.fastx_read("test/MT-orang.fa"): # read a fasta/q sequence
-		for hit in a.map(seq): # traverse alignments
-			print("{}\t{}\t{}\t{}".format(hit.ctg, hit.r_st, hit.r_en, hit.cigar_str))
-
-APIs
-----
-
-Mappy implements two classes and one global function.
-
-Class mappy.Aligner
-~~~~~~~~~~~~~~~~~~~
-
-.. code:: python
-
-	mappy.Aligner(fn_idx_in, preset=None, ...)
-
-This constructor accepts the following arguments:
-
-* **fn_idx_in**: index or sequence file name. Minimap2 automatically tests the
-  file type. If a sequence file is provided, minimap2 builds an index. The
-  sequence file can be optionally gzip'd.
-
-* **preset**: minimap2 preset. Currently, minimap2 supports the following
-  presets: **sr** for single-end short reads; **map-pb** for PacBio
-  read-to-reference mapping; **map-ont** for Oxford Nanopore read mapping;
-  **splice** for long-read spliced alignment; **asm5** for assembly-to-assembly
-  alignment; **asm10** for full genome alignment of closely related species. Note
-  that the Python module does not support all-vs-all read overlapping.
-
-* **k**: k-mer length, no larger than 28
-
-* **w**: minimizer window size, no larger than 255
-
-* **min_cnt**: mininum number of minimizers on a chain
-
-* **min_chain_score**: minimum chaing score
-
-* **bw**: chaining and alignment band width
-
-* **best_n**: max number of alignments to return
-
-* **n_threads**: number of indexing threads; 3 by default
-
-* **fn_idx_out**: name of file to which the index is written
-
-.. code:: python
-
-	mappy.Aligner.map(seq)
-
-This method aligns :code:`seq` against the index. It is a generator, *yielding*
-a series of :code:`mappy.Alignment` objects.
-
-Class mappy.Alignment
-~~~~~~~~~~~~~~~~~~~~~
-
-This class describes an alignment. An object of this class has the following
-properties:
-
-* **ctg**: name of the reference sequence the query is mapped to
-
-* **ctg_len**: total length of the reference sequence
-
-* **r_st** and **r_en**: start and end positions on the reference
-
-* **q_st** and **q_en**: start and end positions on the query
-
-* **strand**: +1 if on the forward strand; -1 if on the reverse strand
-
-* **mapq**: mapping quality
-
-* **blen**: length of the alignment, including both alignment matches and gaps
-  but excluding ambiguous bases.
-
-* **mlen**: length of the matching bases in the alignment, excluding ambiguous
-  base matches.
-
-* **NM**: number of mismatches, gaps and ambiguous poistions in the alignment
-
-* **trans_strand**: transcript strand. +1 if on the forward strand; -1 if on the
-  reverse strand; 0 if unknown
-
-* **is_primary**: if the alignment is primary (typically the best and the first
-  to generate)
-
-* **cigar_str**: CIGAR string
-
-* **cigar**: CIGAR returned as an array of shape :code:`(n_cigar,2)`. The two
-  numbers give the length and the operator of each CIGAR operation.
-
-An :code:`Alignment` object can be converted to a string with :code:`str()` in
-the following format:
-
-::
-
-	q_st  q_en  strand  ctg  ctg_len  r_st  r_en  mlen  blen  mapq  cg:Z:cigar_str
-
-It is effectively the PAF format without the QueryName and QueryLength columns
-(the first two columns in PAF).
-
-Function mappy.fastx_read
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-.. code:: python
-
-	mappy.fastx_read(fn)
-
-This generator function opens a FASTA/FASTQ file and *yields* a
-:code:`(name,seq,qual)` tuple for each sequence entry. The input file may be
-optionally gzip'd.

-\begin{abstract}
-
-\section{Motivation:} Recent advances in sequencing technologies promise
-ultra-long reads of $\sim$100 kilo bases (kb) in average, full-length mRNA or
-cDNA reads in high throughput and genomic contigs over 100 mega bases (Mb) in
-length. Existing alignment programs are unable or inefficient to process such data
-at scale, which presses for the development of new alignment algorithms.
-
-\section{Results:} Minimap2 is a general-purpose alignment program to map DNA or long
-mRNA sequences against a large reference database. It works with accurate short
-reads of $\ge$100bp in length, $\ge$1kb genomic reads at error rate $\sim$15\%,
-full-length noisy Direct RNA or cDNA reads, and assembly contigs or closely
-related full chromosomes of hundreds of megabases in length. Minimap2 does
-split-read alignment, employs concave gap cost for long insertions and
-deletions (INDELs) and introduces new heuristics to reduce spurious alignments.
-It is 3--4 times faster than mainstream short-read mappers at comparable
-accuracy and $\ge$30 times faster at higher accuracy for both genomic and mRNA
-reads, surpassing most aligners specialized in one type of alignment.

-\section{Introduction}
-
-Single Molecule Real-Time (SMRT) sequencing technology and Oxford Nanopore
-technologies (ONT) produce reads over 10kbp in length at an error rate
-$\sim$15\%. Several aligners have been developed for such
-data~\citep{Chaisson:2012aa,Li:2013aa,Liu:2016ab,Sovic:2016aa,Liu:2017aa,Lin:2017aa,Sedlazeck169557}.
-Most of them were five times as slow as mainstream short-read
-aligners~\citep{Langmead:2012fk,Li:2013aa} in terms of the number of bases
-mapped per second. We speculated there could be substantial room for speedup on
-the thought that 10kb long sequences should be easier to map than 100bp reads
-because we can more effectively skip repetitive regions, which are often the
-bottleneck of short-read alignment. We confirmed our speculation by achieving
-approximate mapping 50 times faster than BWA-MEM~\citep{Li:2016aa}.
-\citet{Suzuki130633} extended our work with a fast and novel algorithm on
-generating base-level alignment, which in turn inspired us to develop minimap2
-with added functionality.
-
-Both SMRT and ONT have been applied to the sequencing of spliced mRNAs (RNA-seq). While
-traditional mRNA aligners work~\citep{Wu:2005vn,Iwata:2012aa}, they are not
-optimized for long noisy sequence reads and are tens of times slower than
-dedicated long-read aligners. When developing minimap2 initially for aligning
-genomic DNA only, we realized minor modifications could enable the base
-algorithm to map mRNAs as well. Minimap2 becomes a first RNA-seq aligner
-specifically designed for long noisy reads. We have also extended the original
-algorithm to map short reads at a speed faster than several mainstream
-short-read mappers.
-
-In this article, we will describe the minimap2 algorithm and its applications
-to different types of input sequences. We will evaluate the performance and
-accuracy of minimap2 on several simulated and real data sets and demonstrate
-the versatility of minimap2.
-
-\begin{methods}
-\section{Methods}
-
-Minimap2 follows a typical seed-chain-align procedure as is used by most
-full-genome aligners. It collects minimizers~\citep{Roberts:2004fv} of the
-reference sequences and indexes them in a hash table. Then for each query
-sequence, minimap2 takes query minimizers as \emph{seeds}, finds matches to the
-reference, and identifies sets of colinear seeds, which are called
-\emph{chains}. If base-level alignment is requested, minimap2 applies dynamic
-programming (DP) to extend from the ends of chains and to close unseeded
-regions between adjacent seeds in chains.
-
-Minimap2 uses indexing and seeding algorithms similar to
-minimap~\citep{Li:2016aa}, and furthers the predecessor with more accurate
-chaining, the ability to produce base-level alignment and the support of
-spliced alignment.
-
-\subsection{Chaining}
-
-\subsubsection{Chaining}
-An \emph{anchor} is a 3-tuple $(x,y,w)$, indicating interval $[x-w+1,x]$ on the
-reference matching interval $[y-w+1,y]$ on the query. Given a list of anchors
-sorted by ending reference position $x$, let $f(i)$ be the maximal chaining
-score up to the $i$-th anchor in the list. $f(i)$ can be calculated with
-dynamic programming:
-\begin{equation}\label{eq:chain}
-f(i)=\max\big\{\max_{i>j\ge 1} \{ f(j)+\alpha(j,i)-\beta(j,i) \},w_i\big\}
-\end{equation}
-where $\alpha(j,i)=\min\big\{\min\{y_i-y_j,x_i-x_j\},w_i\big\}$ is the number of
-matching bases between the two anchors. $\beta(j,i)>0$ is the gap cost. It
-equals $\infty$ if $y_j\ge y_i$ or $\max\{y_i-y_j,x_i-x_j\}>G$ (i.e. the
-distance between two anchors is too large); otherwise
-\begin{equation}\label{eq:chain-gap}
-\beta(j,i)=\gamma_c\big((y_i-y_j)-(x_i-x_j)\big)
-\end{equation}
-In implementation, a gap of length $l$ costs
-\[
-\gamma_c(l)=0.01\cdot \bar{w}\cdot|l|+0.5\log_2|l|
-\]
-where $\bar{w}$ is the average seed length. For $m$ anchors, directly computing all $f(\cdot)$ with
-Eq.~(\ref{eq:chain}) takes $O(m^2)$ time. Although theoretically faster
-chaining algorithms exist~\citep{Abouelhoda:2005aa}, they
-are inapplicable to generic gap cost, complex to implement and usually
-associated with a large constant. We introduced a simple heuristic to
-accelerate chaining.
-
-We note that if anchor $i$ is chained to $j$, chaining $i$ to a predecessor
-of $j$ is likely to yield a lower score. When evaluating Eq.~(\ref{eq:chain}),
-we start from anchor $i-1$ and stop the process if we cannot find a better
-score after up to $h$ iterations. This approach reduces the average time to
-$O(h\cdot m)$. In practice, we can almost always find the optimal chain with
-$h=50$; even if the heuristic fails, the optimal chain is often close.
-
-\subsubsection{Backtracking}
-Let $P(i)$ be the index of the best predecessor of anchor $i$. It equals 0 if
-$f(i)=w_i$ or $\argmax_j\{f(j)+\eta(j,i)-\gamma(j,i)\}$ otherwise. For each
-anchor $i$ in the descending order of $f(i)$, we apply $P(\cdot)$ repeatedly to
-find its predecessor and mark each visited $i$ as `used', until $P(i)=0$ or we
-reach an already `used' $i$. This way we find all chains with no anchors used
-in more than one chains.
-
-\subsubsection{Identifying primary chains}\label{sec:primary}
-In the absence of copy number changes, each query segment should not be mapped
-to two places in the reference. However, chains found at the previous step may
-have significant or complete overlaps due to repeats in the reference.
-Minimap2 used the following procedure to identify \emph{primary chains} that do
-not greatly overlap on the query. Let $Q$ be an empty set initially. For each
-chain from the best to the worst according to their chaining scores: if on the
-query, the chain overlaps with a chain in $Q$ by 50\% or higher percentage of
-the shorter chain, mark the chain as secondary to the chain in $Q$; otherwise,
-add the chain to $Q$. In the end, $Q$ contains all the primary chains. We did
-not choose a more sophisticated data structure (e.g. range tree or k-d tree)
-because this step is not the performance bottleneck.
-
-\subsection{Aligning genomic DNA}\label{sec:genomic}
-
-\subsubsection{Alignment with 2-piece affine gap cost}
-
-Minimap2 performs DP-based global alignment between adjacent anchors in a
-chain. It uses a 2-piece affine gap cost~\citep{Gotoh:1990aa}:
-\begin{equation}\label{eq:2-piece}
-\gamma_a(l)=\min\{q+|l|\cdot e,\tilde{q}+|l|\cdot\tilde{e}\}
-\end{equation}
-Without losing generality, we always assume $q+e<\tilde{q}+\tilde{e}$.
-On the condition that $e>\tilde{e}$, it applies cost $q+|l|\cdot e$ to gaps
-shorter than $\lceil(\tilde{q}-q)/(e-\tilde{e})\rceil$ and applies
-$\tilde{q}+|l|\cdot\tilde{e}$ to longer gaps.  This scheme helps to recover
-longer insertions and deletions~(INDELs).
-
-The equation to compute the optimal alignment under $\gamma_a(\cdot)$ is
-\begin{equation}\label{eq:ae86}
-\left\{\begin{array}{l}
-H_{ij} = \max\{H_{i-1,j-1}+s(i,j),E_{ij},F_{ij},\tilde{E}_{ij},\tilde{F}_{ij}\}\\
-E_{i+1,j}= \max\{H_{ij}-q,E_{ij}\}-e\\
-F_{i,j+1}= \max\{H_{ij}-q,F_{ij}\}-e\\
-\tilde{E}_{i+1,j}= \max\{H_{ij}-\tilde{q},\tilde{E}_{ij}\}-\tilde{e}\\
-\tilde{F}_{i,j+1}= \max\{H_{ij}-\tilde{q},\tilde{F}_{ij}\}-\tilde{e}
-\end{array}\right.
-\end{equation}
-where $s(i,j)$ is the score between the $i$-th reference base and $j$-th query
-base. Eq.~(\ref{eq:ae86}) is a natural extension to the equation under affine
-gap cost~\citep{Gotoh:1982aa,Altschul:1986aa}.
-
-\subsubsection{The Suzuki-Kasahara formulation}
-
-When we allow gaps longer than several hundred base pairs, nucleotide-level
-alignment is much slower than chaining. SSE acceleration is critical to the
-performance of minimap2. Traditional SSE implementations~\citep{Farrar:2007hs}
-based on Eq.~(\ref{eq:ae86}) can achieve 16-way parallelization for short
-sequences, but only 4-way parallelization when the peak alignment score reaches
-32767. Long sequence alignment may exceed this threshold. Inspired by
-\citet{Wu:1996aa} and the following work, \citet{Suzuki130633} proposed a
-difference-based formulation that lifted this limitation.
-In case of 2-piece gap cost, define
-\[
-\left\{\begin{array}{ll}
-u_{ij}\triangleq H_{ij}-H_{i-1,j} & v_{ij}\triangleq H_{ij}-H_{i,j-1} \\
-x_{ij}\triangleq E_{i+1,j}-H_{ij} & \tilde{x}_{ij}\triangleq \tilde{E}_{i+1,j}-\tilde{H}_{ij} \\
-y_{ij}\triangleq F_{i,j+1}-H_{ij} & \tilde{y}_{ij}\triangleq \tilde{F}_{i,j+1}-\tilde{H}_{ij}
-\end{array}\right.
-\]
-We can transform Eq.~(\ref{eq:ae86}) to
-\begin{equation}\label{eq:suzuki}
-\left\{\begin{array}{lll}
-z_{ij}&=&\max\{s(i,j),x_{i-1,j}+v_{i-1,j},y_{i,j-1}+u_{i,j-1},\\
-&&\tilde{x}_{i-1,j}+v_{i-1,j},\tilde{y}_{i,j-1}+u_{i,j-1}\}\\
-u_{ij}&=&z_{ij}-v_{i-1,j}\\
-v_{ij}&=&z_{ij}-u_{i,j-1}\\
-x_{ij}&=&\max\{0,x_{i-1,j}+v_{i-1,j}-z_{ij}+q\}-q-e\\
-y_{ij}&=&\max\{0,y_{i,j-1}+u_{i,j-1}-z_{ij}+q\}-q-e\\
-\tilde{x}_{ij}&=&\max\{0,\tilde{x}_{i-1,j}+v_{i-1,j}-z_{ij}+\tilde{q}\}-\tilde{q}-\tilde{e}\\
-\tilde{y}_{ij}&=&\max\{0,\tilde{y}_{i,j-1}+u_{i,j-1}-z_{ij}+\tilde{q}\}-\tilde{q}-\tilde{e}
-\end{array}\right.
-\end{equation}
-where $z_{ij}$ is a temporary variable that does not need to be stored.
-
-An important property of Eq.~(\ref{eq:suzuki}) is that all values are bounded
-by scoring parameters. To see that,
-\[
-x_{ij}=E_{i+1,j}-H_{ij}=\max\{-q,E_{ij}-H_{ij}\}-e
-\]
-With $E_{ij}\le H_{ij}$, we have
-\[
--q-e\le x_{ij}\le\max\{-q,0\}-e=-e
-\]
-and similar inequations for $y_{ij}$, $\tilde{x}_{ij}$ and $\tilde{y}_{ij}$.
-In addition,
-\[
-u_{ij}=z_{ij}-v_{i-1,j}\ge\max\{x_{i-1,j},\tilde{x}_{i-1,j}\}\ge-q-e
-\]
-As the maximum value of $z_{ij}=H_{ij}-H_{i-1,j-1}$ is $M$, the maximal
-matching score, we can derive
-\[
-u_{ij}\le M-v_{i-1,j}\le M+q+e
-\]
-In conclusion, in Eq.~(\ref{eq:suzuki}), $x$ and $y$ are bounded by $[-q-e,-e]$,
-$\tilde{x}$ and $\tilde{y}$ by $[-\tilde{q}-\tilde{e},-\tilde{e}]$, and $u$ and
-$v$ by $[-q-e,M+q+e]$. When $-128\le-q-e<M+q+e\le127$, each of them can be stored as
-a 8-bit integer. This enables 16-way SSE vectorization regardless of the peak
-score of the alignment.
-
-For a more efficient SSE implementation, we transform the row-column coordinate
-to the diagonal-antidiagonal coordinate by letting $r\gets i+j$ and $t\gets i$.
-Eq.~(\ref{eq:suzuki}) becomes:
-\begin{equation*}
-\left\{\begin{array}{lll}
-z_{rt}&=&\max\{s(t,r-t),x_{r-1,t-1}+v_{r-1,t-1},y_{r-1,t}\\
-&&+u_{r-1,t},\tilde{x}_{r-1,t-1}+v_{r-1,t-1},\tilde{y}_{r-1,t}+u_{r-1,t}\}\\
-u_{rt}&=&z_{rt}-v_{r-1,t-1}\\
-v_{rt}&=&z_{rt}-u_{r-1,t}\\
-x_{rt}&=&\max\{0,x_{r-1,t-1}+v_{r-1,t-1}-z_{rt}+q\}-q-e\\
-y_{rt}&=&\max\{0,y_{r-1,t}+u_{r-1,t}-z_{rt}+q\}-q-e\\
-\tilde{x}_{rt}&=&\max\{0,\tilde{x}_{r-1,t-1}+v_{r-1,t-1}-z_{rt}+\tilde{q}\}-\tilde{q}-\tilde{e}\\
-\tilde{y}_{rt}&=&\max\{0,\tilde{y}_{r-1,t}+u_{r-1,t}-z_{rt}+\tilde{q}\}-\tilde{q}-\tilde{e}
-\end{array}\right.
-\end{equation*}
-In this formulation, cells with the same diagonal index $r$ are independent of
-each other. This allows us to fully vectorize the computation of all cells on
-the same anti-diagonal in one inner loop. It also simplifies banded alignment,
-which would be difficult with striped vectorization~\citep{Farrar:2007hs}.
-
-On the condition that $q+e<\tilde{q}+\tilde{e}$ and $e>\tilde{e}$, the initial
-values in the diagonal-antidiagonal formuation is
-\[
-\left\{\begin{array}{l}
-x_{r-1,-1}=y_{r-1,r}=-q-e\\
-\tilde{x}_{r-1,-1}=\tilde{y}_{r-1,r}=-\tilde{q}-\tilde{e}\\
-u_{r-1,r}=v_{r-1,-1}=\eta(r)\\
-\end{array}\right.
-\]
-where

-\eta(r)=\left\{\begin{array}{ll}
--q-e & (r=0) \\
--e & (r<\lceil\frac{\tilde{q}-q}{e-\tilde{e}}-1\rceil) \\
-r\cdot(e-\tilde{e})-(\tilde{q}-q)-\tilde{e} & (r=\lceil\frac{\tilde{q}-q}{e-\tilde{e}}-1\rceil) \\

-\end{array}\right.
-\]
-These can be derived from the initial values for Eq.~(\ref{eq:ae86}).
-
-In practice, our 16-way vectorized implementation of global alignment is three
-times as fast as Parasail's 4-way vectorization~\citep{Daily:2016aa}.  Without
-banding, our implementation is slower than Edlib~\citep{Sosic:2017aa}, but with
-a 1000bp band, it is considerably faster. When performing global alignment
-between anchors, we expect the alignment to stay close to the diagonal of the
-DP matrix. Banding is applicable most of time.
-
-\subsubsection{The Z-drop heuristic}
-
-With global alignment, minimap2 may force to align unrelated sequences between
-two adjacent anchors. To avoid such an artifact, we compute accumulative
-alignment score along the alignment path and break the alignment where the
-score drops too fast in the diagonal direction. More precisely, let $S(i,j)$ be
-the alignment score along the alignment path ending at cell $(i,j)$ in the DP
-matrix. We break the alignment if there exist $(i',j')$ and $(i,j)$, $i'<i$ and
-$j'<j$, such that
-\[
-S(i',j')-S(i,j)>Z+e\cdot|(i-i')-(j-j')|
-\]
-where $e$ is the gap extension cost and $Z$ is an arbitrary threshold.
-This strategy is first used in BWA-MEM. It is similar to X-drop employed in
-BLAST~\citep{Altschul:1997vn}, but unlike X-drop, it would not break the
-alignment in the presence of a single long gap.
-
-When minimap2 breaks a global alignment between two anchors, it performs local
-alignment between the two subsequences involved in the global alignment, but
-this time with the one subsequence reverse complemented. This additional
-alignment step may identify short inversions that are missed during chaining.
-
-\subsection{Aligning spliced sequences}
-
-The algorithm described above can be adapted to spliced alignment. In this
-mode, the chaining gap cost distinguishes insertions to and deletions from the
-reference: $\gamma_c(l)$ in Eq.~(\ref{eq:chain-gap}) takes the form of
-\[
-\gamma_c(l)=\left\{\begin{array}{ll}
-0.01\cdot\bar{w}\cdot l+0.5\log_2 l & (l>0) \\
-\min\{0.01\cdot\bar{w}\cdot|l|,\log_2|l|\} & (l<0)
-\end{array}\right.
-\]
-Similarly, the gap cost function used for DP-based alignment is changed to
-\[
-\gamma_a(l)=\left\{\begin{array}{ll}
-q+l\cdot e & (l>0) \\
-\min\{q+|l|\cdot e,\tilde{q}\} & (l<0)
-\end{array}\right.
-\]
-In alignment, a deletion no shorter than $\lceil(\tilde{q}-q)/e\rceil$ is
-regarded as an intron, which pays no cost to gap extensions.
-
-To pinpoint precise splicing junctions, minimap2 introduces reference-dependent
-cost to penalize non-canonical splicing:
-\begin{equation}\label{eq:splice}
-\left\{\begin{array}{l}
-H_{ij} = \max\{H_{i-1,j-1}+s(i,j),E_{ij},F_{ij},\tilde{E}_{ij}-a(i)\}\\
-E_{i+1,j}= \max\{H_{ij}-q,E_{ij}\}-e\\
-F_{i,j+1}= \max\{H_{ij}-q,F_{ij}\}-e\\
-\tilde{E}_{i+1,j}= \max\{H_{ij}-d(i)-\tilde{q},\tilde{E}_{ij}\}\\
-\end{array}\right.
-\end{equation}
-Let $T$ be the reference sequence. $d(i)$ is computed as
-\[d(i)=\left\{\begin{array}{ll}
-0 & \mbox{if $T[i+1,i+3]$ is ${\tt GTA}$ or ${\tt GTG}$} \\
-p/2 & \mbox{if $T[i+1,i+3]$ is ${\tt GTC}$ or ${\tt GTT}$} \\
-p & \mbox{otherwise}
-\end{array}\right.\]
-where $T[i,j]$ extracts a substring of $T$ between $i$ and $j$ inclusively.
-$d(i)$ penalizes non-canonical donor sites with $p$ and less frequent Eukayotic
-splicing signal ${\tt GT[C/T]}$ with $p/2$~\citep{Irimia:2008aa}. Similarly,
-\[a(i)=\left\{\begin{array}{ll}
-0 & \mbox{if $T[i-2,i]$ is ${\tt CAG}$ or ${\tt TAG}$} \\
-p/2 & \mbox{if $T[i-2,i]$ is ${\tt AAG}$ or ${\tt GAG}$} \\
-p & \mbox{otherwise}
-\end{array}\right.\]
-models the acceptor signal. Eq.~(\ref{eq:splice}) is close to an equation in
-\citet{Zhang:2006aa} except that we allow insertions immediately followed by
-deletions and vice versa; in addition, we use the Suzuki-Kasahara diagonal
-formulation in actual implementation.
-
-If RNA-seq reads are not sequenced from stranded libraries, the read strand
-relative to the underlying transcript is unknown. By default, minimap2 aligns
-each chain twice, first assuming ${\tt GT}$--${\tt AG}$ as the splicing signal
-and then assuming ${\tt CT}$--${\tt AC}$, the reverse complement of ${\tt
-GT}$--${\tt AG}$, as the splicing signal. The alignment with a higher score is
-taken as the final alignment. This procedure also infers the relative strand of
-reads that span canonical splicing sites.
-
-In the spliced alignment mode, minimap2 further increases the density of
-minimizers and disables banded alignment. Together with the two-round DP-based
-alignment, spliced alignment is several times slower than genomic DNA
-alignment.
-
-\subsection{Aligning short paired-end reads}
-
-During chainging, minimap2 takes a pair of reads as one fragment with a gap of
-unknown length in the middle. It applies a normal gap cost between seeds on the
-same read but is a more permissive gap cost between seeds on different reads.
-More precisely, the gap cost during chaining is:
-\[
-\gamma_c(l)=\left\{\begin{array}{ll}
-0.01\cdot\bar{w}\cdot l+0.5\log_2 l & \mbox{if two seeds on the same read} \\
-\min\{0.01\cdot\bar{w}\cdot|l|,\log_2|l|\} & \mbox{otherwise}
-\end{array}\right.
-\]
-After identifying primary chains (Section~\ref{sec:primary}), we split each
-fragment chain into two read chains and perform alignment for each read as in
-Section~\ref{sec:genomic}.  Finally, we pair hits of each read end to find
-consistent paired-end alignments.
-

-800bp.}\label{fig:eval}
-\end{figure}
-
-As a sanity check, we evaluated minimap2 on simulated human reads along with
-BLASR~(v1.MC.rc64; \citealp{Chaisson:2012aa}),
-BWA-MEM~(v0.7.15; \citealp{Li:2013aa}),
-GraphMap~(v0.5.2; \citealp{Sovic:2016aa}),
-Kart~(v2.2.5; \citealp{Lin:2017aa}),
-minialign~(v0.5.3; \citealp{Suzuki:2016}) and
-NGMLR~(v0.2.5; \citealp{Sedlazeck169557}). We excluded rHAT~\citep{Liu:2016ab}
-and LAMSA~\citep{Liu:2017aa} because they either
-crashed or produced malformatted output. In this evaluation, minimap2 has
-higher power to distinguish unique and repetitive hits, and achieves overall
-higher mapping accuracy (Fig.~\ref{fig:eval}a). Minimap2 and
-NGMLR provide better mapping quality estimate: they rarely give repetitive hits
-high mapping quality.  Apparently, other aligners may
-occasionally miss close suboptimal hits and be overconfident in wrong mappings.
-On run time, minialign is slightly faster than minimap2 and Kart. They are over
-30 times faster than the rest.  Minimap2 consumed 6.1GB memory at the peak,
-more than BWA-MEM but less than others.
-
-On real human SMRT reads, the relative performance and sensitivity of
-these aligners are broadly similar to the metrics on simulated data. We are
-unable to provide a good estimate of mapping error rate due to the lack of the
-truth.  On ONT $\sim$100kb human reads~\citep{Jain128835}, BWA-MEM failed.
-Kart, minialign and minimap2 are over 70 times faster than others. We have also
-examined tens of $\ge$100bp INDELs in IGV~\citep{Robinson:2011aa} and can
-confirm the observation by~\citet{Sedlazeck169557} that BWA-MEM often breaks
-them into shorter gaps. The issue is much alleviated with minimap2, thanks
-to the 2-piece affine gap cost.
-
-\subsection{Aligning long spliced reads}
-
-We evaluated minimap2 on SIRV control data~(AC:SRR5286959;
-\citealp{Byrne:2017aa}) where the truth is known. Minimap2 predicted 59\,918
-introns from 11\,018 reads. 93.8\% of splice juctions are precise. We examined
-wrongly predicted junctions and found the majority were caused by clustered
-splicing signals (e.g. two adjacent ${\tt GT}$ sites). When INDEL sequencing
-errors are frequent, it is difficult to find precise splicing sites in this
-case. If we allow up to 10bp distance from true splicing sites, 98.4\% of
-aligned introns are approximately correct. It is worth noting that for SIRV, we
-asked minimap2 to model the ${\tt GT..AG}$ splicing signal only without extra
-bases. This is because SIRV does not honor the evolutionarily prevalent signal
-${\tt GT[A/G]..[C/T]AG}$~\citep{Irimia:2008aa}.

-\subsection{Aligning short genomic reads}
-
-We evaluated minimap2 along with Bowtie2~(v2.3.3; \citealt{Langmead:2012fk}), BWA-MEM and
-SNAP (v1.0beta23; \citealt{Zaharia:2011aa}). Minimap2 is 3--4 times as fast as Bowtie2 and
-BWA-MEM, but is 1.3 times slower than SNAP. Minimap2 is more accurate on this
-simulated data set than Bowtie2 and SNAP but less accurate than BWA-MEM
-(Fig.~\ref{fig:eval}b). Closer investigation reveals that BWA-MEM achieves
-a higher accuracy partly because it tries to locally align a read in a small
-region close to its mate. If we disable this feature, BWA-MEM becomes slightly
-less accurate than minimap2. We might consider to implement a similar heuristic
-in minimap2 in future.
-
-To evaluate the accuracy of minimap2 on real data, we aligned human reads
-(AC:ERR1341796) with BWA-MEM and minimap2, and called SNPs and small INDELs
-with GATK HaplotypeCaller v3.5~\citep{Depristo:2011vn}. This run was sequenced
-from experimentally mixed CHM1 and CHM13 cell lines. Both of them are homozygous
-across the whole genome and have been \emph{de novo} assembled with SMRT reads
-to high quality. This allowed us to construct an independent truth variant
-data set
-(\href{https://github.com/lh3/CHM-eval}{https://github.com/lh3/CHM-eval}) for
-ERR1341796. In this evaluation, minimap2 has higher SNP false negative rate
-(FNR; 2.5\% of minimap2 vs 2.2\% of BWA-MEM), but fewer false positive SNPs per
-million bases (FPPM; 3.0 vs 3.9), lower 2--50bp INDEL FNR (7.3\% vs 7.5\%) and
-similar INDEL FPPM (both 1.0). Minimap2 is broadly similar to BWA-MEM in the
-context of small variant calling.
-
-\subsection{Other applications}
-
-Minimap2 retains minimap's functionality to find overlaps between long reads
-and to search against large multi-species databases such as \emph{nt} from
-NCBI. Minimap2 can also align similar genomes or different assemblies of the
-same species. It took 7 wall-clock minutes over 8 CPU cores to align a human
-SMRT assembly (AC:GCA\_001297185.1) to GRCh38, over 20 times faster
-MUMmer4~\citep{Kurtz:2004zr}.
-
-\section{Discussions}
-
-Minimap2 is a versatile mapper and pairwise aligner for nucleotide sequences.
-It works with short reads, assembly contigs and long noisy genomic and RNA-seq
-reads, and can be used as a read mapper, long-read overlapper or a full-genome
-aligner. Minimap2 is also accurate and efficient, often outperforming other
-domain-specific alignment tools in terms of both speed and accuracy.
-
-The capability of minimap2 comes from a fast base-level alignment algorithm and
-an accurate chaining algorithm. When aligning long query sequences, base-level
-alignment is often the performance bottleneck. The Suzuki-Kasahara algorithm
-greatly alleviates the bottleneck and enables DP-based splice alignment
-involving $>$100kb introns, which was impractically slow ten years ago.  The
-minimap2 chaining algorithm is fast and highly accurate by itself.  In fact,
-chaining alone is more accurate than all the other long-read mappers in
-Fig.~\ref{fig:eval}a (data not shown). This accuracy helps to reduce downstream
-base-level alignment of candidate chains, which is still times slower than
-chaining even with the Suzuki-Kasahara improvement. In addition, taking a
-general form, minimap2 chaining can be adapted to non-typical data types such
-spliced reads and multiple reads per fragment. This gives us the opportunity to
-extend the same base algorithm to a variety of use cases.
-
-Modern mainstream aligners often use a full-text index, such as suffix array or
-FM-index, to index reference sequences. An advantage of this approach is that
-we can use exact seeds of arbitrary lengths, which helps to increase seed
-uniqueness and reduce unsuccessful extensions. Minimap2 indexes reference
-k-mers with a hash table instead. Such fixed-length seeds are inferior to
-variable-length seeds in theory, but can be computed much more efficiently in
-practice. When a query sequence has multiple seed hits, we can afford to skip
-some highly repetitive seeds without affecting the final accuracy. This further
-alleviates the concern with the uniqueness of seeds. Hash table is the ideal
-data structure for mapping long query sequences.

-\ProvidesPackage{natbib}
-        [2000/07/24 7.0a (PWD)]
- % This package reimplements the LaTeX \cite command to be used for various
- % citation styles, both author-year and numerical. It accepts BibTeX
- % output intended for many other packages, and therefore acts as a
- % general, all-purpose citation-style interface.
- %
- % With standard numerical .bst files, only numerical citations are
- % possible. With an author-year .bst file, both numerical and
- % author-year citations are possible.
- %
- % If author-year citations are selected, \bibitem must have one of the
- %   following forms:
- %   \bibitem[Jones et al.(1990)]{key}...
- %   \bibitem[Jones et al.(1990)Jones, Baker, and Williams]{key}...
- %   \bibitem[Jones et al., 1990]{key}...
- %   \bibitem[\protect\citeauthoryear{Jones, Baker, and Williams}{Jones
- %       et al.}{1990}]{key}...
- %   \bibitem[\protect\citeauthoryear{Jones et al.}{1990}]{key}...
- %   \bibitem[\protect\astroncite{Jones et al.}{1990}]{key}...
- %   \bibitem[\protect\citename{Jones et al., }1990]{key}...
- %   \harvarditem[Jones et al.]{Jones, Baker, and Williams}{1990}{key}...
- %
- % This is either to be made up manually, or to be generated by an
- % appropriate .bst file with BibTeX.
- %                            Author-year mode     ||   Numerical mode
- % Then, \citet{key}  ==>>  Jones et al. (1990)    ||   Jones et al. [21]
- %       \citep{key}  ==>> (Jones et al., 1990)    ||   [21]
- % Multiple citations as normal:
- % \citep{key1,key2}  ==>> (Jones et al., 1990; Smith, 1989) || [21,24]
- %                           or  (Jones et al., 1990, 1991)  || [21,24]
- %                           or  (Jones et al., 1990a,b)     || [21,24]
- % \cite{key} is the equivalent of \citet{key} in author-year mode
- %                         and  of \citep{key} in numerical mode
- % Full author lists may be forced with \citet* or \citep*, e.g.
- %       \citep*{key}      ==>> (Jones, Baker, and Williams, 1990)
- % Optional notes as:
- %   \citep[chap. 2]{key}    ==>> (Jones et al., 1990, chap. 2)
- %   \citep[e.g.,][]{key}    ==>> (e.g., Jones et al., 1990)
- %   \citep[see][pg. 34]{key}==>> (see Jones et al., 1990, pg. 34)
- %  (Note: in standard LaTeX, only one note is allowed, after the ref.
- %   Here, one note is like the standard, two make pre- and post-notes.)
- %   \citealt{key}          ==>> Jones et al. 1990
- %   \citealt*{key}         ==>> Jones, Baker, and Williams 1990
- %   \citealp{key}          ==>> Jones et al., 1990
- %   \citealp*{key}         ==>> Jones, Baker, and Williams, 1990
- % Additional citation possibilities (both author-year and numerical modes)
- %   \citeauthor{key}       ==>> Jones et al.
- %   \citeauthor*{key}      ==>> Jones, Baker, and Williams
- %   \citeyear{key}         ==>> 1990
- %   \citeyearpar{key}      ==>> (1990)
- %   \citetext{priv. comm.} ==>> (priv. comm.)
- % Note: full author lists depends on whether the bib style supports them;
- %       if not, the abbreviated list is printed even when full requested.
- %
- % For names like della Robbia at the start of a sentence, use
- %   \Citet{dRob98}         ==>> Della Robbia (1998)
- %   \Citep{dRob98}         ==>> (Della Robbia, 1998)
- %   \Citeauthor{dRob98}    ==>> Della Robbia
- %
- %
- % Citation aliasing is achieved with
- %   \defcitealias{key}{text}
- %   \citetalias{key}  ==>> text
- %   \citepalias{key}  ==>> (text)
- %
- % Defining the citation style of a given bib style:
- % Use \bibpunct (in the preamble only) with 6 mandatory arguments:
- %    1. opening bracket for citation
- %    2. closing bracket
- %    3. citation separator (for multiple citations in one \cite)
- %    4. the letter n for numerical styles, s for superscripts
- %        else anything for author-year
- %    5. punctuation between authors and date
- %    6. punctuation between years (or numbers) when common authors missing
- % One optional argument is the character coming before post-notes. It
- %   appears in square braces before all other arguments. May be left off.
- % Example (and default) \bibpunct[, ]{(}{)}{;}{a}{,}{,}
- %
- % To make this automatic for a given bib style, named newbib, say, make
- % a local configuration file, natbib.cfg, with the definition
- %   \newcommand{\bibstyle@newbib}{\bibpunct...}
- % Then the \bibliographystyle{newbib} will cause \bibstyle@newbib to
- % be called on THE NEXT LATEX RUN (via the aux file).
- %
- % Such preprogrammed definitions may be invoked in the text (preamble only)
- %  by calling \citestyle{newbib}. This is only useful if the style specified
- %  differs from that in \bibliographystyle.
- %
- % With \citeindextrue and \citeindexfalse, one can control whether the
- % \cite commands make an automatic entry of the citation in the .idx
- % indexing file. For this, \makeindex must also be given in the preamble.
- %
- % LaTeX2e Options: (for selecting punctuation)
- %   round  -  round parentheses are used (default)
- %   square -  square brackets are used   [option]
- %   curly  -  curly braces are used      {option}
- %   angle  -  angle brackets are used    <option>
- %   colon  -  multiple citations separated by colon (default)
- %   comma  -  separated by comma
- %   authoryear - selects author-year citations (default)
- %   numbers-  selects numerical citations
- %   super  -  numerical citations as superscripts
- %   sort   -  sorts multiple citations according to order in ref. list
- %   sort&compress   -  like sort, but also compresses numerical citations
- %   longnamesfirst  -  makes first citation full author list
- %   sectionbib - puts bibliography in a \section* instead of \chapter*
- % Punctuation so selected dominates over any predefined ones.
- % LaTeX2e options are called as, e.g.
- %        \usepackage[square,comma]{natbib}
- % LaTeX the source file natbib.dtx to obtain more details
- % or the file natnotes.tex for a brief reference sheet.
