GROMOS(force field)-compatible Parameters for large Organic Drug-like Molecules, Natural Products, Macromolecules and Polymers
Bond Charge Increment (BCI) Model for partial atomic charges
Green Computing ~few seconds of processing
Input - a QM or MM optimized 3D coordinates of the desired protomer/tautomer with all Hydrogen atoms in pdb, mol, sdf, mol2 or pdbqt format
Molecules containing - C, N, O, S, P, F, Cl, Br, I - elements and upto 500 atoms are supported
Output - Gromos (LIG.mtb, 54a7_LIG.ifp), Gromacs (LIG.itp), matching coordinates (LIG.mol2 with BCI charges, LIG.pdb) files
BCI - an alternate charge model for GROMOS, OPLS, GAFF, CHARMM and OpenFF topologies for heteromolecules
