Surface ramp above mode

From PyMOLWiki
Jump to navigation Jump to search

The surface_ramp_above_mode setting is for coloring molecular surfaces by electrostatic potential, using a color ramp. If on, the surface is colored by the potential on the solvent accessible surface, which is one solvent radius above the surface.

Coloring with surface_solvent=0 and surface_ramp_above_mode=0 is less meaningful, since a solvent or ligand atom never reaches the molecular surface of the protein (only the accessible surface). Furthermore, surface_solvent=1 with surface_ramp_above_mode=1 isn't meaningful either.
