This record contains the structure files and Gromacs topologies for the simulations carried out for the publication:David F. Hahn, Vytautas Gapsys, Bert L. de Groot, David L. Mobley, and Gary Tresadern, Current state of open source force fields in protein-ligand binding affinity predictions, 2024.
The data is organized as followed:
