Open Force Field 3.0.0 Alpha Force Field Benchmarks

Summary of benchmarking results on protein structure for the Open Force Field 3.0.0 alpha force field. This is a recording of the Open Force Field Initiative Protein Force Field Meeting on October 16, 2025. The force field "openff_no-water-3.0.0-alpha0.offxml" is called "Null-4-mer-AAQAA3" in this presentation and is colored orange throughout. QM parameter fits made use of code from https://github.com/openforcefield/protein-param-fit. NMR parameter fits made use of code from https://github.com/openforcefield/protein-nmr-fit. Benchmarks of protein structure made use of code from https://github.com/openforcefield/proteinbenchmark.
