TCGA Pan-Cancer sample, 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 information for Project Cognoma.<br>`expression-genes.tsv` provides information and summary statistics for every gene in `expression-matrix.tsv.bz2`.<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>`mutation-genes.tsv` provides information and summary statistics for every gene in `mutation-matrix.tsv.bz2`.<br>`samples.tsv` is a sample × attribute matrix providing sample information and clinical measures for each sample.<br>`covariates.tsv` is a sample × attribute matrix for modeling that encodes categorical variables in samples.tsv using dummies.<br>All datasets contain the same samples as rows (in the same order). No two samples correspond to the same patient.<br>The data was retrieved from the UCSC Xena Browser.<br>These datasets were created by the GitHub repository commit below. 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 the expression and mutation datasets.
