Thanks for opening this PR, @epehrsson! Sorry I didn't notice it -- in the future you can tag me with @kelly-sovacool somewhere in the this thread to notify me if you want me to review it.

Were you able to run this successfully on biowulf?

Hi @kelly-sovacool, sorry for not tagging you! Yes, I could run it on the test data and on two projects I'd processed earlier, which recapitulated the results of the rules. =

Thanks for this contribution @epehrsson! I proposed changes here so that your new rules will also use the docker container. Please take a look and merge that if it looks good, then we'll run one more test to make sure I didn't break anything before merging this PR into main.
