[chimerax-users] help with chimerax wildcards

[Elaine Meng]

Hi Mike,
Are you sure you didn’t use Chimera syntax, which has the color before the spec? That is the common reason for this error.

Your command looks fine, and works for me when I try it in daily build (2/19) and 0.8 release (12/17/2018).

However, the simpler approach for element N is just to use element symbol:

color N blue

Also if you don’t want to also color the ribbons entirely blue (all amino acids have N), you may want to add that target is atoms:

color N blue target a
 - or -
color N blue atoms

I hope this helps,
Elaine
