I was going to compare gene expression in primary tumor and normal control.

So I downloaded PAN cancer data from xena.USCS.edu (https://tcga.xenahubs.net/download/TCGA.PANCAN.sampleMap/PANCAN_clinicalMatrix
 for clinical matrix and  
https://toil.xenahubs.net/download/tcga_RSEM_gene_fpkm
for gene expression TOIL Gene RSEM fpkm dataset.

Then I selected patient that have matched normal and primary tumor sample types, and I found that for each gene, fpm from normal and primary tumor are JUST THE SAME!

I wonder what's wrong with this. 



Is there anybody helping me? Thanks in advance!
In almost all cases cases, each TCGA patient only had tumor RNAseq done. ([see previous discussions][1]). Are you sure that there was actually normal RNAseq available, or have you pulled down the same file twice through different linkages?
