   (Load a molecule first, from above or below choices)

Calculate a surface on the currently selected set of atoms:
(caution! may take several seconds or even minutes)

• solvent-accesible surface:
• solvent-excluded surface (1.2 Å):
• solvent-excluded surface (1.4 Å)
• Last isoSurface:

Or choose pre-made examples of molecular surfaces
