OpenFF Biopolymer FF meeting: tetrapeptide torsion profiles

Open Force Field protein force field meeting. Chapin Cavender presented a benchmark of OpenFF force fields against tetrapeptide torsion profiles from TorsionDrives from Dave Cerutti (slides attached). The presentation was followed by a group discussion on how to relax the coordinates of quantum mechanics (QM) energy minima using a molecular mechanics (MM) force field for a torsion profile benchmark and how to choose library charges for a protein force field.
