Hi Martin, You must be looking at the "development" documentation online. The Coulombic Surface Coloring tool was added after release 1.3, so to use it you would want to get a Chimera daily build (just give that a different name or put it in a different place if you want to also keep 1.3 around). Daily build download: <http://www.cgl.ucsf.edu/chimera/alpha-downloads.html> Here is the list of what's new since the production release: <http://www.cgl.ucsf.edu/chimera/docs/relnotes/snapshot.html> Best, Elaine ----- Elaine C.

Hello,
I saw on the Chimera online manual that there is a Coulombic Surface Coloring function, which displays an approximate electrostatic potential without having to calculate a file with delphi etc.
This sounds great and I would love to use the function.
However, in the Tools > Surface/Binding Analysis menu, I don't find it.
Is it something to be implemented in future versions of Chimera? Or is there a way of using it in the current release (I have version 1.3 build 2577 from December 9)
Thanks a lot! Martin
