Hi Maia, just tun off the occupancy refinement. You can do it by removing the "*" in front of "occupancies", as illustrated below: strategy = *individual_sites rigid_body *individual_adp group_adp *tls \ *occupancies *group_anomalous Pavel. On 11/4/2008 11:26 AM, chern wrote:
How can I give occupancy 0.5 to my ligands and avoid occupancy refinement? Because the refinement gave me some atoms with occupancy 0.0 and adjacent atoms with occupancy 1.0 in the same ligand.

Ralf,
it's not that uncommon. See for example: http://www.rcsb.org/pdb/files/1ejg.pdb
Also, you may want to couple partially occupied residue's side chain with partially occupied water.

Hi Tassos,
However, I want to refine my MET residues in double conformations, one as MET (AMET) and the other one as MSE (BMSE) with each 0.5 occupancy to start with.
In addition to what Pavel wrote: I just tried out the AMET BMSE mix without giving any manual atom selections, and it works fine for me. (P.S.: I'm thrilled to see this use of the multiple-conformers-with-mixed-residue-names feature, since it was a lot of work.)
