You can download COSMIC cancer mutation data programmatically by running the provided Python script, which uses the requests library to authenticate with your COSMIC account and stream core mutation files like CosmicMutantExport.tsv.gz directly into your pipeline.

Yes, accessing Cancer Gene Census and mutational signatures data requires a COSMIC account for authentication. The Python script uses your credentials to authenticate the session before fetching and streaming any cancer genomics resources.

You can retrieve both GRCh38 and GRCh37 core mutation data using Python and requests. The script authenticates your COSMIC account and fetches the specific genome build's mutation export files for downstream cancer genomics analysis.

Besides core mutations, available COSMIC data resources include the Cancer Gene Census, mutational signatures, structural variants, copy number, gene expression, resistance mutations, and sample information for integrated cancer genomics workflows.

The best way to integrate COSMIC data with gene expression datasets is to programmatically download the core mutation files using the Python script, then load the TSV outputs into pandas or R to filter by gene and merge with expression data.

COSMIC data download scripts fail during authentication if your COSMIC account credentials are invalid or missing. The script requires successful authentication via the requests library before it can stream any cancer mutation or gene census files.
