Cell line mutation correlation

I am perplexed in trying to download cell line - mutation data.
I have the file CCLE_mutations.csv.
It seems to have no column for the cell line, or some cell line annotation, like organ of origin.
I cannot find a file on your download page that has both. This seems quite odd.

Hi David, the cell line arxspan IDs are in the column DepMap_ID. You can find their names, organ of origin, etc in the sample_info.csv
