Dear Pymol users,
 
 
 
I have to compare 20 different structures of the same protein, all  with the same origin.
The protein is a homotetramer and I am interested in comparing the catalytic pocket of each monomer inside a single structure and across the 20 structures.
Also I would like to compare not only the same monomer across all the structures but also compare  different monomers from different structures.
To be more clear I would like to have the following layout in the pymol menu:
 
 
Mutant1
Catalytic pocket monomer A
Catalytic pocket monomer B
Catalytic pocket monomer C
Catlytic  pocket  monomer  D
 
Mutant2
 
Catalytic pocket monomer A
Catalytic pocket monomer B
Catalytic pocket monomer C
Catlytic  pocket  monomer D
 
and so on for all of 20, to be able to compare the catalytic pocket of one monomer of one structure with the monomer of another structure simply selecting and deselecting from the menu.
In order to do this, I have to find a way to superimpose all the 80 monomers on the top of each other applying  the same selection and view of the catalytic pocket to all of them and keeping the link with the original pdb in a way that there is a distinction for e.g  from monomer A of mutant 1 and monomer A of any other mutant.
Can anyone suggest to me a way to do this without generating 80 objects and keeping the exact same view of the catalytic pocket for all of them?
 
Thank you in advance,
