[Chimera-users] changing appearance of dashed lines

Hi Arthur,
Those dashed lines are “pseudobonds” (like H-bond and distance-measuring lines).  You can Ctrl-click to select one and then click the green magnifying glass icon near the bottom right of the Chimera window to show the Selection Inspector. 

In the Selection Inspector, you can Inspect “Pseudobond” and change its color by:
(1) turning “halfbond mode” to “off”, AND
(2) clicking on the square color-well and using the resulting Color Editor dialog to choose a color.  The color will not be visible in the display unless you turn halfbond mode off.

To change line thickness, Inspect “Pseudobond group” (click on the “Pseudobond” and you can see it is a menu where you can change to “Pseudobond group” instead) and then change the “line width” value.

Or, you could do all these things with the “setattr” command
…of which there are a few examples in these previous posts:

I hope this helps,

In the Chimera structure it is represented by a series of dashed lines.  How can I increase the thickness of those branched lines and even change their color from the rest of the protein.
