[Chimera-users] Defining Attribute Color for Surface Independent of Atoms

Chimera Folks, I have set up a file to define a series of colors based on functional measurements for some residues in a PDB file. I would like to color the ball and stick atoms according to element type and a semi-transparent surface according to the colors defined by my text file. It seems like these two things are tied together; that the surface can either be colored by the model, the atoms, or a specific color. Can I color it according to a Defined Attribute but leave the atoms as CPK coloring? Thanks, David
