TCGA purity data
... 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.

rsem matrix to DESeq2
... I know that I can pass the gene-level rsem matrix to limma and work with it. But can I use it in DESeq? I've a rsem matrix from firebrowse, gene-level ~20000 rows. DESeq requires raw counts, and as I only have the matrix with samples/gene I can't use tximport(). Thanks ...
