Hi Miguel, Conrad Huang is writing new molecular surface code and I believe it will also calculate solvent accessible surfaces. We recently decided it will not be ready for the next Chimera production release in a few months. It is a complex calculation and I'm not sure when it will be available. Chimera can read a GRASP surface from a file (just use File / Open, file suffix .srf) and color it in the same way it colors MSMS surfaces. Tom Miguel Ortiz Lombardia wrote:

Hi Tom,
I would like to know if there has been any advancement in changing the surfaces code. I know you had plans to write your own so that chimera would not rely on msms, and I am very interested in this development because it would allow the use of solvent accessible surfaces apart from molecular surfaces. The former are more appropriate, among other questions, to map electrostatic potential maps (less local effects). I would be happy to test around, if you need testers. Unfortunately my programming skills are quite minimal.
But I'll be patient anyway ;-) Thanks to all of you for this great tool!
Cheers,
Miguel
