[Chimera-users] Looking for a Ramachandran plot display

Hi all, I'm looking for a tool or an extension that displays the Ramachandran plot of a protein model, similar to the DeepView (SPDBViewer) tool. I'm not interested in the interactive features, just the display of residues as dots on the phi/psi plane, with dots colored, for example, by their C-Alphas' color. Do you know if such a tool was written for Chimera? With regards, Oren
