Dear All,

Once we load a PDB in chimera, in Tools-Higher order structure-Unit Cell, if we click "Make copies", the copies of the PDB would be created based on space group, with each copy has a specific # (0,1,2,3..., for example).

Will you please let me know is any rule  available for how the number of # for each copy of PDB was defined? It seems the PDB copies with consecutive specific # were not most closely related in the Chimera display.

I am looking forward to getting a reply from you.

Smith
