[Chimera-users] Display Molecule Name

[Elaine Meng]

Hi Chris,
The labelopt/label commands control the "regular" or 3D labels, which  
are totally different than 2D labels.  As mentioned in my message  
yesterday (below), the way to change the size of 3D labels is in the  
preferences.

The 2D labels are created with the "2D Labels" tool and/or the  
"2dlabels" command.  The name is something you assign yourself when  
creating the 2D label with the "2dlabels" command.

The 3D labels are associated with atoms and residues and move along  
with the structure, whereas 2D labels are arbitrary text/symbol  
strings that you can place anywhere in the X,Y plane of the screen  
and do not move along with the structure.  Please see the links in my  
previous message for details.

I hope this helps,
Elaine
