Sample names must contain at least underscore (?)

Description of the bug

Hey!

I was running the nascent pipeline v2.1.1 (v2.2.0 didn't work due to #) for two runs of the same sample.

I encountered an error at the step of samtools sort:

I checked out #113, but solution was not applicable to my case. By trying different things, I found out that the reason is in the sample name. Initially, I put a name EXP, and it failed. I put a longer name, DUTTKE and it failed again. But it is running now fine with sample name DUTTKE_REP1.

So, apparently, v2.1.1 requires sample names to have at least one underscore. I cannot test it on v2.2.0 due to another bug, but could you please add this info to the docs?

Hey!

This isn't intended, I'll make a PR with a test case for this, and see if it's still happening on dev!
