Intra-tumor Heterogeneity / Mutation Cellular Fraction in TCGA Data

Question

[Noushin N]

Hello,

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.

Thank you,
