APBS Electrostatics Plugin


The APBS Electrostatics Plugin integrates the APBS software package into PyMOL. Its primary purpose is electrostatic surface visualization. It superseedes the APBS Tool2.1 plugin.

New in Incentive PyMOL 2.0


A molecule must already be loaded into PyMOL.

For regular protein and DNA molecules, the plugin should be a one-click solution (just click "Run").

For RNA, the residue names might need adjustment, see troubleshooting RNA.

Non-protein/DNA/RNA molecules or modified residues need special preparation, see #Prepare Molecule.


The default procedure involves three steps:

  1. preparing the molecule by assigning partial charges and adding hydrogens and other missing atoms
  2. calculating the electrostatic map
  3. visualization of the charged molecular surface

Each step can be run individually by unchecking the checkboxes on the other steps.
