Tools for asserting matching pairs of samples from the same patient

In a RNA-Seq project, I have 10 samples, 2 each from 5 patients. I would like to make sure the patients or sample pairs were labeled properly and that there was no mix up.

I used the counts from HT-Seq to generate MDS and scatter plots to assess them. The plots suggest, there might be a mix up.

But I wanted to know if there are tools for such analysis, which take in FastQ or BAM files.

Any suggestions appreciated. Thanks!

You could use DeepTools. It Accepts BAM files and plots a Principal component analysis of the coverage within bins of a size determined by the user.

That's the kind of tool I was looking for. Thanks!

Rather than passing by BAM files, it may be faster and better to quantify transcripts with an alignment-free program like Kalisto and do a PCA or MDS plot on the transcript expressions.
