This is a placeholder page to begin discussion/planning regarding biopolymer force fields. David Cerutti (Deactivated) will soon begin working in this area. On Slack, see #ff-biopolymers.

Objective

Build an OpenFF protein force field

Objectives for 2020:

Bring in an AMBER protein force field to SMIRNOFF format
Build an OpenFF protein force field (and later, biopolymer) which includes protein-specific parameters where needed (especially torsions) but works naturally with the small molecule force field

Team

Project leader: David Cerutti (Deactivated)

Team members: Jeffrey Wagner David Mobley and others TBD

Tasks:

Michael Shirts - let us know when Cerutti start date looks likely to be (resolved, he is starting now).
David Mobley and Jeffrey Wagner coordinate re Cerutti onboarding/initial work plan
