I need some help!
I'm working with TCGA-HNSC data using the TCGAbiolinks package which I already have previous experience. I downloaded and normalized the data. Later, I separated into low expression and high expression groups for DEG analysis. Now I would like to validate my DEGs using DEGs from other GEO banks - GSE65858, for example.
How should I proceed? Should I download raw data? Or download the standard available in GEO2R?
