Hi all,

I am following the tutorial for plotting electrostatic potentials for APBS
(http://www.poissonboltzmann.org/apbs/examples/visualization/apbs-electrostatics-in-pymol). Everything is normal, nevertheless it crashes
when I try to plot the solvent accessible surface, no matter the Solvent
accessible surface and Color by potential on sol. acc. surf. are

What should I suppose to do? Thank you so much.
