Hi everybody: I am trying to repeat the procedures in this paper DOI: https://doi.org/10.1016/j.ccell.2016.04.001. It needs syn3242754 data to complete, it is a data about TCGA project tumor purity, I try to ask for the data in Synapse, but they tell me that I must be a menber of TCGA team, or looking for it elsewhere. So will some one know how to become a menber of TCGA menber or where else can I access the data? thanks!
