I have been trying to find if TCGA PRAD (prostate cancer) RNA-seq data strand specific or not. I can not find any relevant info. I did find that it is Illumina protocol, but nothing more. Does anyone if they are strand specific? Do you have the right link?
Thanks
The short answer is no. 

The specific RNA-Seq library preparation kit TCGA used actually "could" support stranded library; however, it was used in a manner that libraries are actually strandless.
