[Chimera-users] Color surface by electrostatic potential vs color by value at atom position

[Yu Zhou]

Hi there,

I want to color protein surface by electrostatic potential datacalculated using APBS 1.5. I tried two methods in Chimera and got quite differentresults. The resulted images can be found in attachment. 

In the first attached figure (fig1_ep surface) the surface wascolored by the “Electrostatic Surface Coloring” tool, in the second attachedfigure (fig2_value atom) the surface was colored by the “Values at AtomPositions” tool. Same color palette (red: -35, white: 0, blue: +35) and potential file was used in bothcases. 

Thanks for your help.

Yu Zhou
