[Chimera-users] Preparation of the protein-ligand system for the amber simulation

Dear Chimera Users, I wounder to know if it's possible to use combination of the amber ff with the cgenff for the both parametrization of the small ligands in complex with the proteins using amber tools built in Chimera's? Does it possible to use some scripts instead of GUI for such tasks ? I'll be thankfull for some tutorial or example Thanks for help, James
