Rene, The problem is that each biological unit copy in the PDB is handled as a separate molecular state (i.e. a movie), which then become distinct states in PyMOL. Hit play to see what I mean.
To solve this, the most recent versions of PyMOL can split multi-state objects into multiple single-state objects automatically: load 1f41_tetra.pdb split_states 1f41_tetra dele 1f41_tetra With older versions, you'll need to create the new objects manually load 1f41_tetra.pdb create 1f41_tetra_1, 1f41_tetra, source_state=1, target_state=1 create 1f41_tetra_2, 1f41_tetra, source_state=2, target_state=1 dele 1f41_tetra Cheers, Warren -- mailto:war...@delanoscientific.com Warren L.
