Project updates

LW

  • Past week

    • General MSM

    • Evaluator – fixing bugs, trying to get this running on NRP

    • OpenFE collab on SFEs

  • Next week

    • Project plans – trying to fix some of the organization structure in Confluence

      • Meeting with JE on this, then will check in maybe next week’s meeting

    • Lipid force field fitting

Project updates

BW

  • Past week

    • lipidmaps clustering

      • With threshold of 0.65, clustered fragments down to ~1800

      • Some fragments can be very large (~300 atoms)

      • Cap fragments with H for now, can’t remember what previous issue with S was

      • Don’t bother with >70 heavy atoms. Might need to filter out full molecules from the fragment set. This is for training data. Aiming for ~4k molecules to start with

      • ~100 heavy atoms for molecules for benchmark data

    • benchmarking visualization tool

      • BW: plan to get AWS runner working, scale up to full size benchmark

      • BW: will port code into repo

      •  

    • optimizations

      • (see Slack thread)

  • Next week

    • lipidmaps dataset?

    • benchmarking CI

      • ping LW or AMI if want feedback

    • yammbs PR reviews

    • follow-up on the minimization issue and re-do torsion minimizations in new environment

Project updates

AMI

  • Past week

    • DDX dataset

      • 1/3 calcs with PBE0 crashed with numerical issues, e.g. SCF convergence issues. Many of those that didn’t crash may have also converged to the wrong state. JW suggested increasing memory

      • Using vacuum wfns as SCF guess may fix it. Technically challenging

      • Can also try huckel guess, which is less technically challenging

    • MSM splits

  • Next week

    • Troubleshoot DDX dataset

    • Maybe train FF based on MSM splits?
