I was wondering if anyone is aware of an online resource where information on mutation cancer cell fraction estimates for TCGA samples can be retrieved.
I am aware of two excellent studies which have performed the exact analysis to derive the above. But I cannot locate the corresponding values in the available supplementary data.
