[Chimera-users] Wire thickness

[Elaine Meng]

Hi Hernando,
To summarize for you and others:  first you have to show sticks instead of wires, then set the stick radii.

In Chimera, the individual bond “radius” (default 0.2 Angstroms) is multiplied by molecule-model “stickScale” (default 1.0) to give the stick radius.  You can change these attributes in the Selection Inspector (opened with green magnifying glass after making a selection) or with the “setattr” command.  Since changing stickScale would change it for the whole model, you instead want to specify the bond “radius” attribute separately for the backbone and non-backbone bonds, for example:

setattr b radius 0.1 protein
setattr b radius 0.25 @n,ca, c,o

… substituting whatever radius values you really wanted. 

I hope this helps,
Elaine
