RNAseq pipeline changing my sample names

[AnnaDvdH]

Description of the bug

Hello,

I've been having some issues when running the rnaseq pipeline in Uppmax. It seems like the pipeline is automatically switching the names of my samples, which makes it really difficult to trace which sample is which.

I am working with tumour data, so my samples contain a T from tumour, followed by a number, for example 07TDOXTAK_NC_T3. However, in my results the samples are all being switched to something like 07TDOXTAK_NC_T1. Since I have several tumours from the same individual, I really need to keep the number after the T.

I got some help already through the slack channel, and I got recommended to switch my sample name to something else. This is because the pipeline uses _T<DIGIT> to name technical replicates and because I am adding it as my sample name, it is breaking the assumptions in the pipeline. I did this, so now my samples don't end with a T1 but with a NC (something like 07TDOXTAK_T3_NC), however, I am getting the error again and all my samples are being switched to 07TDOXTAK_NC_T1 with the _T1 at the end, and not NC. I am a bit lost and not sure what to test next.

Thank you in advance for all the help!

@AnnaDvdH having done some testing I believe this issue is now resolved in dev. If I change the samples in the test profile to have _T2, _T3 etc as suffixes, they retain those into the results in the output directory (see multiqc report attached).

@drpatelh may be able to explain the detail of the fix, but I believe it's a consequence of #1058.

Closing the issue for now. If you feel I've misunderstood, or determine that the fix does not apply to what you're doing, feel free to reopen.
