Hi All,
I am having some problems with surface display of the output from the
APBS plugin distributed with PyMOL (version 1.1r0) using the "color by
potential on sol. acc. surf." option. Steps to reproduce the problem:
1. Load in a structure.
2. Perform the APBS calculation (execute "Set grid" and "Run APBS"
functions/buttons).
3. Show the electrostatics on the molecular surface under the
Visualization tab. I used the following options
Low = -5
High = 5
"solvent accessible surface" = selected
"color by potential on sol. acc. surf." = selected
The initial surface displayed looks OK, and there are no problems if I
rotate the molecule using the mouse. However, if I attempt to rotate
the molecule using a command such as "rotate y, 180",, the surface
coloring is distorted. If I execute "rotate y, 180" again, then
rotate by hand, the distortion on the problematic surface-side
disappears. However, if I execute "rotate y, 180" once, or some
iteration != 360, then rotate the molecule using the mouse, the color
distortion is present and will not disappear with subsequent rotate
commands.
Thanks in advance for help,
Doug
