[AMBER] PDDG-PM3/MMGBSA calculation

Hi,

    I want to calculate the free energy of binding of a ligand into the
binding cleft of a protein by QM-MMGBSA approach and MMPBSA.py.

By PM3 and AM1 hamiltonians all the results were correctly obtained but
if I wanted to use PDDG-PM3 methods I had this error:

        /Beginning GB calculations with ...//
        // calculating complex contribution...//
        // calculating receptor contribution...//
        // calculating ligand contribution...//
        //IndexError: list index out of range//
        //Exiting. All files have been retained//
        /

No errors were found in the temporary files. I suppose that the problem
could be in the final scripts able to capture the energy values from
_MMPBSA_* files.

Thanks in advance for help.

Giovanni
