Description

In pVACview we noticed that the transcript values rarely add up to something close to the gene value (which is almost always quite a bit higher).

We should double check the right numbers are being pulled in?

If so, maybe back up and look at the upstream step in the rna-seq pipeline to make sure tximport is doing the right thing?

Research direction

Start by tracing how pVACview pulls transcript and gene expression values from kallisto results, then inspect the upstream RNA-seq pipeline step involving tximport. Compare the values at each stage to determine whether the discrepancy is in pVACview or the pipeline; done means identifying the source of the mismatch and defining the required correction.
