Clonality Estimates of SCNA in TCGA samples

Question

[christoph.kreitzer93]

Hi all :)

I am willing to use Somatic Copy Number Alteration - TCGA data (specifically TCGA-COAD) for some validation studies. I do know that segmented data is readily available to download, however, I am wondering whether there is a comprehensive file listing the clonality (clonal vs subclonal) of derived segments (for every sample in respective tumour type). Specifically, every SCNA-segment in patient X (e.g. COAD cancer) and corresponding clonality estimate (perhaps run on ABSOLUTE or related tools).

Many thanks, chris.
