Re: [AMBER] Fwd: Amber parameters for Boron atom

I was willing to modify gaff.dat file because creating an Frcmod I could not use antechamber for ligand parametrisation anyway. In fact, differently from tutorial ( <>) I need a ligand prepin file to set up my complex, and moreover I need antechamber for the charge RESP fitting of my ESP potentials calculated with Gaussian.
