[chimerax-users] coil thickness

[Elaine Meng]

Dear Lisandro Otero,
Sorry, you cannot change the coil thickness only for a specific part of a model.  It always applies to the whole model.  "The subcommands cartoon style and cartoon tether control per-model settings":
<https://rbvi.ucsf.edu/chimerax/docs/user/commands/cartoon.html#style>

However, you could try opening an extra copy of the same structure, and then showing only that loop in the second copy.  E.g. if you wanted to do this for the coil at residues 245-252 of structure 2mnr:

open 2mnr
open 2mnr
hide #1:245-252 targ ac
hide #2 & ~ :245-252 targ ac
cartoon style #2 & coil thick .8

Meaning: open two copies of structure (model #1 and model #2).  Hide residues 245-252 of #1, both atoms and cartoons.  Hide residues except for 245-252 of #2, both atoms and cartoons. Make coil of #2 cartoon thicker.  You can see #2 is a different color than #1, but you can make it the same color, e.g.

color #2 & C tan targ ac

I hope this helps,
Elaine
