[Chimera-users] Surface mesh and coloring queries

Dear Chimera friends, Good day. Please enlighten on the following queries, a) I would like to know if I can write the surface mesh calculated within chimera to a file. From the documentation of the surface command, it seems that it is not possible. My idea is to have the vertices and faces as outputs to be fed to a plotting tool aimed for webpage display. Please guide me if this is possible or the related source code I can modify to have the output. b) How does chimera color surfaces, for instance, coulombic surface. What I am not understanding is the way the surface colors are interpolated to atomic charges. I would like to adopt the method for my plotting purpose. Thanks in advance, Bala -- C. Balasubramanian
