Hi,
I am new to genomic scene and I am trying to analyse the expression of some genes in various types of prostate cancer. I just have one query regarding data I have downloaded from cBioportal.. are the values for "mRNA expression" z-scores or log2 values? I am having some trouble understanding this as some values are negative while others are round large numbers eg: 35, 60 etc.
Thanks a lot for your help!
At which particular file are you looking (link)? - RSEM / RNA-seq v2?
They are most likely Z-scores, as per this previous question: What is the unit of TCGA RNA-seq data downloaded from cBioPortal?
