APBS-generated electrostatic surface displayed in PyMOL
APBS, the Adaptive Poisson-Boltzmann Solver, is a
freely
available macromolecular electrostatics calculation program released under a
BSD license.
PyMOL can display the results of the calculations as an electrostatic potential molecular surface.
Both plugins make it possible to run APBS from within PyMOL, and then display
the results as a color-coded electrostatic surface (units )
in the molecular display window (as with the image to the right).
