Minimization settings

 

  • Some concern about this change affecting results

  • LM – Did some digging on this, have a few slidfes I can show. LW and I think we should stick with the previous /default criteria. In the longer run we thought it could be helpful to have it be a user-settable parameter but it’ll be easy for those details to get lost in the data store.

  • MT – Right, there isn’t machinery to support multiple MM conformers for a single mol.

  • LM – Yeah, there would need to be some way to record the provenance of each MM opt.

  • MT – So I think this is approaching a decision point where you+LW currently want this to be set to default, with an open issue to discuss user-customaization here.

    • LM – Yes, LW and I basically agreed that.

  • MT – This sounds like having different optimization settings in different benchmarks wouldn’t have a SYSTEMATIC effect, but should rather have a RANDOM effect.

  • LM – For geo opts - part of the benchmarking is MM optimization from the QM opt. Sometimes this will lead to leaving the QM minimum and heading to a more global minimum. So having looser convergence criteria will likely change results, by taking fewer steps and staying closer to QM minimum.

Org transfer

MT

  • Made openforcefield/YAMMBS repo, old URLs should redirect gracefully

  • Not planning on making conda packages for a while longer

  • Re: reproducibiity, all that should be needed is a tag.

  • JW – Maybe all deps for this repo should have their versions explicitly pinned?

    • MT – Deps in actual studies run are captured in conda list output. Explicitly pinning all deps could be a wide range of work depending on how thoroughly we want to do it. I think handling this in the study artifacts is fine.

    • JW – Sounds good.
