registration/convert fails on older nextflow version

[levje]

To reproduce: NXF_VER="24.04.2" nf-test test --tag registration/convert

Running this with NXF_VER="25.04.6.5954" works fine. From what I tested, it does not seem to work with Nextflow 24.xx.

Error (following is only the output of the first test, but all tests fail):

@levje I think this was covered by a recent PR. Can you confirm and close please ?

[levje]

@AlexVCaron I confirm that this issue is still occurring on main. Are you getting this error when running NXF_VER="24.04.2" nf-test test --tag registration/convert on your setup?

[AlexVCaron]

Ok. I'll address this. I though you fixed it in a newer PR on this repo, but maybe it was scoped to nf-tractoflow in the end. Let me look into it.

I'm tempted to flag this as a non-issue and promote/force everything linked to nf-neuro to Nextflow 25.
