I have downloaded the TCGA dataset for ACC Cancer type from RNAseqV2 data. In the level 3 files for the RSEM rnaseq data, the barcodes for the samples are given as follows : "TCGA-OR-A5J1-01A-11R-A29S-07".
How to understand whether the sample is tumor or normal? In here, TCGA description for barcode , the barcode explained is given in different manner. Any help would be appreciated.
