TCGA purity data

Question

[Folder40g]

Hi

I know that Cosmics offers a file with the purity for each tumor sample but no BAF or LogR, but I'm interested in running ascat on some TCGA samples to obtain Germline/Tumor BAF and LogR for a downstream analysis.

Do you know if there is any database with this information available? I've not found anything and i would like to be sure of this before running it by my own.

Thanks
