You told antechamber that you were giving it a pdb file, but you actually
gave it a BIOSYM archive file. Since antehcamber didn't find any ATOM
records, it thought there were no atoms in the molecule.
Take a look at the ANTECHAMBER_MUL.MOP file: this is the input to mopac. You
have to get that correct first.
....good luck...dac
