[Chimera-users] Helix-Numbers

[Elaine Meng]

Hi Sudheer,
Sounds like you want 2D labels (Tools... Utilities... 2D Labels):
<http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/2dlabels/2dlabels.html 
 >

Since these labels don't move when you rotate the structure, you would  
first find the position you want to show in your figure, and then add  
the labels.

Alternatively, for labels in 3D that move with the structure, you  
could just label one atom in each helix and then manually change what  
is in the label (for example with "Actions... Label... other...").   
However, for figures I think 2D labels are much better, since they  
allow more control over location and can include symbols such as Greek  
letters, and it is easier to change their sizes and colors.

Some example images with 2D labels:

Best,
