Many of our matrices are log normalized, which tends to eliminate
the number of non zero values (if there were any). This prevents
the matrix from being stored as a sparse matrix. The solution here
is to use a simple transformation to make it sparse again. The most
common value from each column is subtracted from that column. These
values that were subtracted are saved in an array called X_col_shift.
The cellxgene code needs to understand how to undo the transformation when
operating over the X matrix.
- added script to create a synthetic dataset for testing
- added a script to convert an existing CXG dataset to a sparse CXG dataset
* Add server plugin system
Plugins are optional modules loaded at runtime. Specification:
* Plugins are loaded from the server.plugins module (directory
server/plugins)
* The import_plugins method is run as part of the initialization of the
server module in __init__.py
* Add plugins to the EB build process
* Remove bit of dead code
* Respond to feedback from @bmccandless
* Add user-defined category-label colors
Fixes https://github.com/chanzuckerberg/cellxgene/issues/1152
As described in https://github.com/chanzuckerberg/cellxgene/issues/1307
* Respond to feedback from @bkmartinjr in nodejs
* Respond to feedback from @bkmartinjr in python

* Make colors_get error handling specific
* Respond to feedback from @bkmartinjr
* Respond to feedback from @bkmartinjr
* Fix whitespace
* Fix python lint errrors
* Update documentation
* Add --disable-user-colors option to launch and cxgtool.py
* Fix python formatting
* Rename '--disable-user-colors' to '--disable-custom-colors'
* Introduce a config file to cellxgene
The config file format is in yaml. The default config is located
in server/common/default_config.py. A user may create a yaml file
that contains a subset of these fields. It can be used during cellxgene
launch, or for hosted cellxgene.
The code has also been refactored. Much of the logic to check arguments
has moved from launch to app config.
It is now possible to set the tiledb context parameters using the config
file. Other feature will soon be handled in a similar way.
* Add user-generated annotations tests to the server
Partially completes https://github.com/chanzuckerberg/cellxgene/issues/969
