Hi Felix
I'm hardly an expert, also new, but MAJIQ seems to require a license. I would ask in the general help thread to make sure it is compatible, and how nf-core deals with licenses.
Also, with regards to software, one question tjhat seems important to ask is "Which parts are duplicated"? For example, glancing at IRFFinder-S paper, it seems that it has a FASTQ mode, which will lead to alignment. Do you have to include the alignment in the IRFFinder, or can you use the regular alignment module?
Cheers,
Uri David
