Hi Simon, one of possible ways: just change the starting occupancy values to something between 0 and 1, for example, set them to 0.9. That will be a sign for Phenix to refine their occupancies. Yours way should work too (though I don't know all the details, including what's in .def file), but may be you try resetting occupancies first? Pavel On 5/15/12 2:27 AM, Simon Kolstoe wrote:
Hi phenixbb,
I'm wanting to refine the occupancy for just a few Cadmium atoms in a structure but not refine any other occupancies. I've used the following command however the occupancies haven't refined:
phenix.refine refinement_006.def occupancies.individual="chain X and element CD2"
and the cadmiums are in the pdb file as:
ATOM 8740 CD+2 CD2 X 1 -81.043 91.612 65.218 1.00 11.63 X CD2+ ATOM 8741 CD+2 CD2 X 2 -78.111 92.072 62.948 1.00 11.15 X CD2+ ATOM 8742 CD+2 CD2 X 3 -85.283 28.170 80.931 1.00 12.01 X CD2+
Thanks,
Simon
