Dyda, By default, PyMOL uses charges and radii from the Amber99 forcefield, as per APBS. The PDB2PQR tool included with APBS enables you to use other charge/radius sets, such as CHARMM.
Chain IDs need to be removed for PQR...though future versions of PyMOL do this automatically. Cheers, Warren\ -- Warren L. DeLano, Ph.D. Principal Scientist .
