The script extracts mutational signatures from VCFs, MAF and cbioportal studies. Also contains a dockerfile in order to easily install dependencies.

This is the back-end implementation of RFC64.

Related front-end PR cBioPortal/cbioportal-frontend#4540 containing the front-end implementation.
Related datahub PR cBioPortal/datahub#1784 containing some studies with extracted mutational signatures

The script extracts mutational signatures from VCFs, MAF and cbioportal studies. Also contains a dockerfile so dependencies are easily installed.

prolly good if this is a specific version - or have some way to capture on datahub what version was run to generate the signature data
