Hi Ibrahim, I can't give the exact command because I don't know the center of your system. The command help is here: <https://rbvi.ucsf.edu/chimerax/docs/user/commands/color.html#distance> So the form of the command could be something like color radial <surf-model> center <center-spec> coordinateSystem <ref-model> ... where ways to specify the center are: • x,y,z (three values separated by commas only) – an arbitrary point, interpreted in scene coordinates unless a different coordinateSystem is given • an atom-spec – the center of the bounding box of the specified items • cofr – the current center of rotation • camera – the viewer position None of those are the same as center of screen, unless you are using the center-of-rotation method that tracks center of view: <https://rbvi.ucsf.edu/chimerax/docs/user/commands/cofr.html> I hope this helps, Elaine ----- Elaine C.

Dear all,
I am trying to color a cryoem map radially in ChimeraX (to get something similar to surface color by radius in chimera).
I used the following comand:
color radial #model
However, the map is colored from one side to the other instead of radial coloring starting from the center. I tried to specify the center of the screen as 0,0,0 but that did not help.
What is the correct command/options to do radial coloring in ChimeraX?
Thanks for help, Ibrahim
