[Open Babel] atom types force field

[Osvaldo M. <alo...@gm...>]

Hi,

I need to get the atom types from molecules. I am using a Python/PyMOL
script. I have the following code


def get_atom_type(selection):
    pdb_string = cmd.get_pdbstr(selection)
    mol = ob.OBMol()
    obconversion = ob.OBConversion()
    obconversion.SetInAndOutFormats('pdb', 'pdb')
    obconversion.ReadString(mol, pdb_string)
    ff = ob.OBForceField.FindForceField('GAFF')
    ff.Setup(mol)
    return at.GetType() for at in ob.OBMolAtomIter(mol)


The atom type from babel are too simple for my needs. How can I get the
atom types from the forcefield?

Thanks in advance,
Osvaldo.
