I would like to download the mRNA expression z-scores for all genes (in all patients, with all cancers) from CBioPortal. I've found the download page, but I have to enter a list of genes I want the z-scores for - I don't want particular genes, I want to download all of them.
This data is normally available from the TCGA, but in this case I understand the z-scores are calculated from TCGA data by CBioPortal, and I'd rather not recalculate them myself. Is it possible to do a bulk download of all z-scores from CBioPortal?
Thanks for any help,
