Hi.
I need to use pdb2pqr in a molecule that I am studying but it does not have the GROMOS53a6 force field available. I know that there is an option to add a force field but it has to be in a specific format (.DAT and .names). I understand the .DAT file structure and download the GROMOS53a6 force field from gromacs website but I cannot manage to convert from one to another because I could not find the radius of each atom in the GROMOS53a6 files. Does anyone could help me with it?
Thanks in advance.
