Hi @random-annoym, could you share an example of your samplesheet and toolsheet?

I think the error happens because you have empty header fields. If you do not want to provide an optional column, you can just leave it out, but not use the comma

e.g.
id,fasta,

will give an error,

id,fasta
will not :)

Let me know if that works and if I can help any further.

I will close this now, in case there were more doubts I am happy to discuss :)
