Hi JD, There is another way I didn't think of earlier, if you want to "clone" a model after making several changes instead of having to make the same changes to each copy. Open the structure, make the changes, save a session. Then, repeatedly open the session, which will put additional copies of the first model in successive model numbers if you answer "No" when prompted whether the existing model(s) should be closed. However, if you will be doing H-bond or clash detection either independently or within swapaa or Rotamers, I recommend against stacking the structures, as that will affect the calculations. The same problem applies to opening the same PDB file multiple times. Best, Elaine ----- Elaine C.

Hi,
Is there a way to copy, in the same instance of chimera, a model X time? I'd like to generate different mutant of the same prot and have them stocked in the same session of chimera.
Cheers, JD
