I am a bit confused about finding control and tumor samples in TCGA.
I have read this https://docs.gdc.cancer.gov/Encyclopedia/pages/TCGA_Barcode/ and many other posts but does not help much to know.
Lets have an example
TCGA means by itself 41 is TSS? if so, then what should I understand from it? 4097 is the participant number , right? 01 is sample ? or portion? A is vial or analyte?
I am trying to find Normal and Control in data
