Hello, There is command "color byattribute" and you need to give the name of the attribute "seq_rmsd". For the RMSD attribute to be assigned to residues, you need to have the RMSD header shown on a sequence alignment window, and the structures associated with a sequence in that window. color byattribute command: <https://rbvi.ucsf.edu/chimerax/docs/user/commands/color.html#byattribute> However, the easier way may be to use the graphical interface, menu: Tools... Structure Analysis... Render by Attribute. You still need to have the sequence alignment with RMSD header as above, but then in this Render by Attribute tool you can choose attribute of "residues" named "seq_rmsd" and set the coloring how you like. This will show the resulting command in the Log so later you can just use the command instead of the tool if you prefer. How to do it is shown in a video: <https://www.youtube.com/watch?v=XaTpB-UIxnU> Render by Attribute tool: <https://rbvi.ucsf.edu/chimerax/docs/user/tools/render.html> I hope this helps, Elaine ----- Elaine C.
