[Elaine Meng]

Dear Valerio,
It should not matter, each is still a separate model.  If you open the PDB as model #0 but it contains an NMR ensemble, the members are models #0.1, #0.2, … etc.

I don’t know what steps you are using, but you can control exactly which structure(s) in which to show a particular residue in several ways.  Here are just two ways:

Ctrl-click to select the ribbon segment of just one residue in one structure (this mainly works for where they are not too close together), menu: Actions… Atoms/Bonds… show

Use a command, for example to show residue 45 of chain A in the 5th ensemble member of model 0 only:

display #0.5:45.A

You can use the balloon information that pops up when you hold the mouse cursor over some part a of a structure to tell you which model number and which residue it is.

Again, it is just the same as if you have multiple non-NMR structures open.
I hope this helps,
Elaine

>>> I would like to produce images from chimera showing an NMR bundle structure (backbone only) with stick-represented residues each one belonging to different single structures. I know it´s possible to do it with pymol but unfortunately the structures superimposition is not as good as in chimera. Would it be possible?
