2022-06-01 Mitchell/Wagner Check-in meeting notes

Updates

• JW – The support email is finally getting emails from someone. Let me send you the credentials

  • JM was able to log into support email, but JW had to disable login challenges for 10 min using this page: https://admin.google.com/ac/users/1t3h5sf0yfhr18/security?hl=en

• JW – Nice catch on mutablemappings and python 3.10

• JW – Lily is now acting science lead

• JW – One spot I found in the docs that will fall out of date after the 0.11 release:

  • https://docs.openforcefield.org/projects/toolkit/en/stable/users/molecule_cookbook.html#via-topology-objects - Molecule.from_topology is no longer the best way - Can just do Topology.molecule(0)

• JW – What would be helpful in the coming week or two or three would be intense polishing of the topology refactor branch - So things like:

  • SHOULD BE BASED OFF https://github.com/openforcefield/openff-toolkit/pull/1306 (or wait until this is merged)

  • Better error messages when loading proteins (either OFF or OMM should raise a descriptive error about the following):

    • “This protein is missing explicit Hs”

    • “This looks like a modified amino acid”

    • “I don’t like this cap”

    • This can only be a single molecule in a PDB file

    • missing atoms/unresolved loops

  • Good tests could be:

    • a protein without Hs

    • A protein with a modified AA

    • a protein with unresolved atoms

    • a pdb with two proteins

    • a pdb with a protein and xtal waters (suggest how to separate them using eg. mdanalysis or pdbfixer or something before loading)

• Make hierarchy get perceived when you run perceive residues, in other words:

• ala_cysdye_ala.perceive_residues() ala_cysdye_ala.add_default_hierarchy_schemes() ala_cysdye_ala.perceive_hierarchy()

  should be refactored to

• ala_cysdye_ala.perceive_residues()
