@Nick Edmunds have you done any of the Nextflow training so far? Or are you a complete beginner? The proteinfamilies issues/modules are a good starting point for module level nf-tests. We are currently creating one on the local site and will be hopefully done within the next 2 hours. Then we can try working on another one together. Or even better, tomorrow through a call. A good starting point (until then) would be to look at existing nf-core modules and see how nf-tests are written and try to execute some of those locally on your machine!
