Reads with / characters in the read names cause the pipeline to fail

Check Documentation

I have checked the following places for your error:

• [X] nf-core website: troubleshooting
• [X] nf-core/clipseq pipeline documentation

Description of the bug

If / characters are in the read names, then the pipeline will fail at the dedup step. This is caused, however, by STAR truncating read names based on the / character. This removes the UMI information which was added earlier in the pipeline, causing the dedup step to fail.

Steps to reproduce

Steps to reproduce the behaviour:

Running the pipeline with reads with a / in the read name. Example

Expected behaviour

Either a verbose error message saying that the reads are incompatible, or automatic removal or replacement of the / characters.
