[Chimera-users] question about label chain?

[Elaine Meng]

Dear user,
For making nice labels that can be any sizes and colors for figures and movies, we usually recommend 2D Labels (graphical interface) or for scripting, the 2dlabels command.  These 2D labels just stay in the place that you put them and do not automatically move with the structure.

2D Labels GUI:

2dlabels command:

See also movie example command files:

Here's a nice example open-access publication with two movies that have 2D labels and arrows:
<https://www.nature.com/articles/s41467-021-24651-2>

However, if you meant labels that automatically move with the structure, then you have to use custom atom ("3D") labeling.   There isn't really a label chain, instead you have to choose which atoms to label and then show the chain info in the atom label.  For example you could select one atom, then open Selection Inspector (by clicking the green magnifying glass on the bottom right corner of the window), then just enter in the "label" field whatever you want the label to say.  Or, you could use menu: Actions... Label... other... and again enter what you want the label to say. 

Those "3D labels" are all the same size as each other, controlled in the Preferences (category: Labels) and you'd need to use "color" to change their colors.

I hope this helps,
Elaine
