COSMIC Mutational Signatures Data Files
Download current and previous releases of COSMIC mutational signatures here.
Files are organized by release, genome, and mutation type. Once you have selected the version that you would like to download, click the highlighted text by the download icon to save the file to your computer.
Each file is tab separated and the rows are the mutational contexts and the columns are the reference signatures. Each column sums to one and the values in each column are the contributions of the mutational context to that signature.
