TCGA Pan-Cancer expression and mutation data for Project Cognoma

The following datasets were created for Project Cognoma:<br>`expression-matrix.tsv.bz2` is a sample × gene matrix indicating a gene's expression level for a given sample. This dataset will be the feature/x/predictor for Project Cognoma.<br>`mutation-matrix.tsv.bz2` is a sample × gene matrix indicating whether a gene is mutated for a given sample. Select columns (or unions of several columns) in this dataset will be the status/y/outcome for Project Cognoma.<br>These are preliminary datasets for development use and machine learning. The data was retrieved from the UCSC Xena Browser.<br>All original work in the data is released under CC0. However, the license of TCGA and Xena data is currently unclear.<br>These two datasets were created by the GitHub repository commit below, although they were not tracked due to large file size. See the download directory of the cancer-data repository for metadata files with the version info for the Xena downloads this release is based on.<br>See the data/subset directory of the cancer-data repository on GitHub to browse small subsets of these datasets.
