I'm trying to dock a zinc complex, but when I tried to prepare the ligand, I get an error saying that there are no Gasteiger parameters available for it. I know you can add atom types in Autodock 4.2, so I was wondering if the same can be done in Crankpep. If so, where is the parameter file located? I have not had luck finding it, but then again, I am kind of new to linux and probably have not utilized all the tools available for looking for files.
