2022-04-27 Mitchell/Wagner Check-in meeting notes

General updates

• BSwope – “Bespokefit docs are really top notch”

  • Notes from bespokefit working session:

    • OMP_NUM_THREADS and n_cpus for XTB should be recommended to be 1 (it’s much slower if more CPUs are added thanks for quirks in QCEngine)

    • Made a Swope example - Could be good for docs/example material

openff-bespoke executor run 
--smiles "CC(=O)NC1=CC=C(C=C1)O"                            
--workflow "default" 
--output "acetaminophen.json" 
--output-force-field "acetaminophen.offxml" 
--n-qc-compute-workers 6         
--qc-compute-n-cores   1 
--default-qc-spec xtb gfn2xtb none

• JW – Could be neat to turn the above into an example, though it may go slightly beyond the strict scope of bespokefit - It uses OpenMMForceFields' TemplateGenerator to load the bespoke FF, and then OpenMM’s Modeller to add a solvent box. So maybe something in a toolkit/higher-level user example showing how to set up multi-component simulations with bespoke FFs (possible also including a protein?)

• JM – Could make this an optional section in the toolkit showcase?

  • JW – That’s a good idea. Could have an if statement that defaults to False but that a user could override to do a bespoke fit.

• JM – The Interchange and OpenFF Toolkit “toolkit showcase” examples are nearly identical

  • JW – I anticipate the Interchange showcase superseding the toolkit one.

  • JM – Maybe we should have centralized examples for stuff that spans repos?

  • JW – That’s a good idea. Could take the following examples from the OFF Toolkit and I won’t ask any questions:

    • swap_amber_parameters (both examples in here)

    • toolkit_showcase (since it will be superseded by toolkit-and-interchange-and-maybe-also-bespokefit showcase)

    • using_smirnoff_in_maber_or_gromacs

    • using_smirnoff_with_amber_protein_force_field

• JM – I hooked up docs.openforcefield.org

Todos

1. (high) QCSubmit users guide (in progress)

2. (high) Interchange pre-release prep

3. (medium) Toolkit docs cleanup

4. (medium) Toolkit revised user guide (+-unifying/centralizing package user guides)

5. (medium)

6. (medium) Come up with “milestones” for making first of three videos this year (like, “first video on covid spike protein and small molecule, filmed this day, edited in that range, etc…”)
