> an interactive explorer for single-cell transcriptomics data
-`cellxgene` is an interactive data explorer for single-cell transcriptomics datasets, such as those coming from the [Human Cell Atlas](https://humancellatlas.org). Leveraging modern web development techniques to enable fast visualizations of at least 1 million cells, we hope to enable biologists and computational researchers to explore their data, and to demonstrate general, scalable, and reusable patterns for scientific data visualization.

+## get in touch
-**Note**: automatic opening of the browser with the `--open` flag only works on OS X, on other platforms you'll need to directly point to the provided link in your browser.
+Have questions, suggestions, or comments? You can come hang out with us by joining the [CZI Science Slack](https://join-cellxgene-users.herokuapp.com/) and posting in the `#cellxgene-users` channel. As mentioned above, please submit any feature requests or bugs as [Github issues](https://github.com/chanzuckerberg/cellxgene/issues). We'd love to hear from you!
-There are several options available, such as:
+## where we are going
-- `--layout` to specify the layout as `tsne`, `umap`, `diffmap`, `phate`, `draw_graph_fa`, or `draw_graph_fr`
-- `--title` to show a title on the explorer
-- `--open` to automatically open the web browser after launching (OS X only)
+Our goal is to enable teams of computational and experimental
+biologists to collaboratively gain insight into their single-cell RNA-seq data.
-To see all options call
+There are 4 key features we plan to implement in the near term.
-```
-cellxgene launch --help
-```
+- Click install and launch
+- Manual annotation workflows
+- Toggle embeddings
+- Gene information
-There is an additional subcommand called `cellxgene prepare` that takes an existing dataset in one of several formats and applies minimal preprocessing and reformatting so that `launch` can use it (see [the next section](##data-formatting) for more info on `prepare`).
+For more detail on these features and where we are going, see [our roadmap](ROADMAP.md).
-## data formatting
+## contributing
-### assumptions
+We warmly welcome contributions from the community! Please submit any bug reports and feature requests through [Github issues](https://github.com/chanzuckerberg/cellxgene/issues). Please submit any direct contributions by forking the repository, creating a branch, and submitting a Pull Request. It'd be great for PRs to include test cases and documentation updates where relevant, though we know the core test suite is itself still a work in progress. And all code contributions and dependencies must be compatible with the project's open-source license (MIT). If you have any questions about this stuff, just ask!
-The `launch` command assumes that the data is stored in the `.h5ad` format from the [`anndata`](https://anndata.readthedocs.io/en/latest/index.html) library. It also assumes that certain computations have already been performed. Briefly, the `.h5ad` format wraps a two-dimensional `ndarray` and stores additional metadata as "annotations" for either observations (referred to as `obs` and `obsm`) or variables (`var` and `varm`). `cellxgene launch` makes the following assumptions about your data (we recommend loading and inspecting your data using `scanpy` to validate these assumptions)
-
-- an `obs` field has a unique identifier for every cell (you can specify which field to use with the `--obs-names` option, by default it will use the value of `data.obs_names`)
-- a `var` field has a unique identifier for every gene (you can specify which field to use with the `--var-names` option, by default it will use the value of `data.var_names`)
-- an `obsm` field contains the two-dimensional coordinates for the layout that you want to render (e.g. `X_umap` for the `umap` layout)
-- any additional `obs` fields will be rendered as per-cell continuous or categorical metadata by the app (e.g. `louvain` cluster assignments)
-
-### prepare
-
-The `prepare` command is included to help you format your data. It uses `scanpy` under the hood. This is especially useful if you are starting with raw unanalyzed data and are unfamiliar with `scanpy`.
-
-To prepare from an existing `.h5ad` file use
-
-```
-cellxgene prepare dataset.h5ad --output=dataset-processed.h5ad
-```
-
-This will load the input data, calculate QC metrics, perform PCA and nearest neighbor calculations, compute `umap` and `tsne` layouts and `louvain` cluster assignments, and save the results in a new file called `dataset-processed.h5ad` that can be loaded using `cellxgene launch`. Data can be loaded from several formats, including `.h5ad` `.loom` and a `10-Genomics-formatted` `mtx` directory. Several options are available, including running one of the preprocessing `recipes` included with `scanpy`, which include steps like cell filtering and gene selection. To learn more about the `recipes` please see the `scanpy` [documentation](https://scanpy.readthedocs.io/en/latest/api/index.html#recipes).
-
-Depending on the options chosen, `prepare` can take a long time to run (a few minutes for datasets with 10-100k cells, up to an hour or more for datasets with >100k cells). If you want `prepare` to run faster we recommend using the `sparse` option and only computing the layout for `umap`, using a call like this
-
-```
-cellxgene prepare dataset.h5ad --output=dataset-processed.h5ad --layout=umap --sparse
-```
-
-To see all options call
-
-```
-cellxgene prepare --help
-```
-
-**Note**: `cellxgene prepare` will only perform `louvain` clustering if you have the `python-igraph` and `louvain` packages installed. To make sure they are installed alongside `cellxgene` use
-
-```
-pip install cellxgene[louvain]
-```
-
-If the aforementioned optional package installation fails, you can also install these packages directly:
-
-```
-pip install python-igraph louvain>=0.6
-```
-
-## conda and virtual environments
-
-If you use conda and want to create a conda environment for `cellxgene` you can use the following commands
-
-```
-conda create --yes -n cellxgene python=3.7
-conda activate cellxgene
-pip install cellxgene
-```
-
-Or you can create a virtual environment by using
-
-```
-ENV_NAME=cellxgene
-python3.7 -m venv ${ENV_NAME}
-source ${ENV_NAME}/bin/activate
-pip install cellxgene
-```
-
-## docker
-
-We have included a dockerfile to conveniently run cellxgene from docker.
-
-1. Build the image `docker build . -t cellxgene`
-2. Run the container and mount data `docker run -v "$PWD/example-dataset/:/data/" -p 5005:5005 cellxgene launch --host 0.0.0.0 data/pbmc3k.h5ad`
- - You will need to use --host 0.0.0.0 to have the container listen to incoming requests from the browser
-
-## FAQ
-
-
-
- questions about data formatting
-
-
-
-> Someone sent me a directory of `10X-Genomics` data with a `mtx` file and I've never used `scanpy`, can I use `cellxgene`?
-
-Yep! This should only take a couple steps. We'll assume your data is in a folder called `data/` and you've successfully installed `cellxgene` with the `louvain` packages as described above. Just run
-
-```
-cellxgene prepare data/ --output=data-processed.h5ad --layout=umap
-```
-
-Depending on the size of the dataset, this may take some time. Once it's done, call
-
-```
-cellxgene launch data-processed.h5ad --layout=umap --open
-```
-
-And your web browser should open with an interactive view of your data.
-
-
-
-> In my `prepare` command I received the following error `Warning: louvain module is not installed, no clusters will be calculated. To fix this please install cellxgene with the optional feature louvain enabled`
-
-Louvain clustering requires additional dependencies that are somewhat complex, so we don't include them by default. For now, you need to specify that you want these packages by using
-
-```
-pip install cellxgene[louvain]
-```
-
-
-
-> I ran `prepare` and I'm getting results that look unexpected
-
-You might want to try running one of the preprocessing recipes included with `scanpy` (read more about them [here](https://scanpy.readthedocs.io/en/latest/api/index.html#recipes)). You can specify this with the `--recipe` option, such as
-
-```
-cellxgene prepare data/ --output=data-processed.h5ad --recipe=zheng17
-```
-
-It should be easy to run `prepare` then call `cellxgene launch` a few times with different settings to explore different behaviors. We may explore adding other preprocessing options in the future.
-
-
-
-> I have extra metadata that I want to add to my dataset
-
-Currently this is not supported directly, but you should be able to do this manually using `scanpy`. For example, this [notebook](https://github.com/falexwolf/fun-analyses/blob/master/tabula_muris/tabula_muris.ipynb) shows adding the contents of a `csv` file with metadata to an `anndata` object. For now, you could do this manually on your data in the same way and then save out the result before loading into `cellxgene`.
-
-
-
-> What part of the anndata objects does cellxgene pull in for visualization?
-
-- `.obs` and `.var` annotations are use to extract metadata for filtering
-- `.X` is used to display expression (histograms, scatterplot & colorscale) and to compute differential expression
-- `.obsm` is used for layout
-

-
-
- questions about installing and building
-
-
-
-> I tried to `pip install cellxgene` and got a weird error about missing paths to an HDF5 library?
-
-You probably just need to install HDF5 first. If you're on a mac, you can simply `brew install hdf5` and then try `pip install cellxgene` again.
-
-> I tried to `pip install cellxgene` and got another weird error I don't understand
-
-This may happen, especially as we work out bugs in our installation process! Please create a new [Github issue](https://github.com/chanzuckerberg/cellxgene/issues), explain what you did, and include all the error messages you saw. It'd also be super helpful if you call `pip freeze` and include the full output alongside your issue.
-
-
-
-> I'm following the developer instructions and get an error about "missing files and directories” when trying to build the client
-
-This is likely because you do not have node and npm installed, we recommend using [nvm](https://github.com/creationix/nvm) if you're new to using these tools.
-
-
-
-
-
- questions about algorithms
-
-
-
-> How are you computing and sorting differential expression results?
-
-Currently we use a [Welch's _t_-test](https://en.wikipedia.org/wiki/Welch%27s_t-test) implementation including the same variance overestimation correction as used in `scanpy`. We sort the `tscore` to identify the top N genes, and then filter to remove any that fall below a cutoff log fold change value, which can help remove spurious test results. The default threshold is `0.01` and can be changed using the option `--diffexp-lfc-cutoff`. We can explore adding support for other test types in the future.

+# cellxgene roadmap
+
+We are very exited for _cellxgene_ to become a valuable tool in collaborations
+between computational biologists and experimental biologists working on
+single-cell transcriptomics data. _cellxgene_ is in active development, and we
+would love to include the community as we plan new features to work on. If you
+have questions of feedback about this roadmap, please submit an issue on
+GitHub.
+
+Please note: this roadmap is subject to change.
+
+*Last updated: April 11, 2019*
+
+## what we are building now
+
+In the near term, our goal is to enable teams of computational and experimental
+biologists to collaboratively explore and annotate their single-cell RNA-seq data.
+
+There are 4 key features we plan to implement in the near term.
+
+- Click install and launch
+- Manual annotation workflows
+- Toggle embeddings
+- Gene information
+
+### simple install and launch
+
+The command line interface for installing and launching cellxgene is a barrier
+for users who are not used to Python or using the command line. We plan to
+support installation and launch of cellxgene on Mac and Windows. See
+[Issue #687](https://github.com/chanzuckerberg/cellxgene/issues/687) for more details.
+
+### manual annotation workflows
+
+The exploratory visualization that cellxgene offers is critical for manual
+annotation workflows, especially in collaborative environments. We plan to
+support manually annotate cells with labels (i.e., cell type or QC flags) for
+downstream analysis. See [Issue #524](https://github.com/chanzuckerberg/cellxgene/issues/524)
+for more details.
+
+### toggle embeddings
+
+While a single dataset may have multiple embeddings calculated (tSNE, umap, in
+situ coordinates, trajectories, etc), cellxgene currently requires the user to select the
+embedding to use in the main layout at launch. We plan to support letting users
+toggle between any embedding present in a file from the cellxgene interface.
+See [Issue #594](https://github.com/chanzuckerberg/cellxgene/issues/594) for details.
+
+### gene information
+
+Differential expression returns only the names of genes, but no additional information
+about gene metadata, function, or known associations. We plan to help users learn
+more about genes they discover by exposing additional gene metadata. See
+[Issue #96](https://github.com/chanzuckerberg/cellxgene/issues/96) for details.
