<p class="ydp7a85a323MsoNormal">I want to color protein surface by electrostatic potential data
calculated using APBS 1.5. I tried two methods in Chimera and got quite different
results. The resulted images can be found in attachment. </p>
<p class="ydp7a85a323MsoNormal">In the first attached figure (fig1_ep surface) the surface was
colored by the “Electrostatic Surface Coloring” tool, in the second attached
figure (fig2_value atom) the surface was colored by the “Values at Atom
Positions” tool. Same color palette (red: -35, white: 0, blue: +35) and potential file was used in both
cases. </p>
<p class="ydp7a85a323MsoNormal">Thanks for your help.</p>
