[chimera-dev] Fwd: Question about coloring the points on a Ramachandran plot

[Eric Pettersen]

Hi Trina,
	I'm forwarding this to the chimera-dev list to give the "Ramachandran plot guy" (Conrad Huang) a chance to answer.  I think he's recently done many of the same things for a custom script so he's better suited for answering...

I want to do this so that the selected residue point is visible when it is behind a lot of points. I got it to be somewhat successful, however, only half of the points turn out this way. The other half turned out to be blacked out and I'm not sure why.
