I have trouble coloring only a narrow range of residues (1-10) in one chain (P) of one model (#18). I've tried a few options:

color sequential #18/P:1-10

This colors the entire chain P in rainbow colors (equivalent to atom selection #18/P).

color sequential #18:1-10/P

This colors _all_ residues of all chains in model #18 -- except of one chain which lacks residues 1-10.

I also tried with the "rainbow" synonym. When this failed, I tried coloring according to the residue number:

 

color byattribute r:number #18/P:1-10       

This throws an error "Unknown/unregistered Residue attribute number", although number should be an attribute of residues according to this page: https://www.cgl.ucsf.edu/chimerax/docs/user/attributes.html#residue

Am I doing something wrong? Is this feature not implemented yet? Is there a work-around?

Regards,

Daniel
