WebLigParGen is a web-based service that provides force field (FF) parameters for organic molecules or ligands, offered by the Jorgensen group. LigParGen provides bond, angle, dihedral, and Lennard-Jones OPLS-AA parameters with 1.14*CM1A or 1.14*CM1A-LBCC partial atomic charges. Server provides parameter and topology files for commonly used ... WebUnlike AMBER, which stores all the force field parameters directly in a prmtop file, Gromacs just stores references to force field definition files that are installed with the Gromacs application. OpenMM needs to know where to find these files, so the includeDir parameter specifies the directory containing them.
