[Chimera-users] Labeling the surface representation

Hi Mehdi,
If you mean the information that automatically appears when you put  
the mouse cursor over the residue, by default it just shows  
information for the whole surface.  If you instead want to see  
information about individual atoms/residues, here are instructions:

"Sometimes one would rather see information for the atoms under a  
surface than for the surface itself. This can be achieved by making  
the surface unselectable with the mouse, for example by:

    1. selecting the surface, either picking it with the mouse or  
using the Model Panel
    2. opening the Selection Inspector, by choosing Actions... Inspect  
or clicking the button near the lower right corner of the main Chimera  
    3. in that dialog, inspecting Surface and changing selectable with  
mouse to false

Then, an atomspec balloon will report information for the atom under  
the cursor position, not necessarily the same as the atom giving rise  
to the surface patch under the cursor position. The atoms must be  
displayed for their atomspec balloons to appear, but they do not need  
to be visible; they could be behind opaque surface. However, the  
surface can be made transparent (with Actions... Surface...  
transparency or the command surftransparency) to allow viewing the  
underlying atoms at the same time."

These instructions, with hyperlinks, are in the User's Guide:

I hope this helps,
