Hi John,
here is the complete refinement example emulating exactly what you are
trying to do:
http://cci.lbl.gov/~afonine/group_occ_refinement/
Just look at the files and run "run" file to see the result. It takes
less than 20 secs to run on my computer. All it does, it refines one
occupancy for alternative conformation A and one occupancy per
alternative conformation B. Note the selections I used to specify the
groups.
Please let me know if you have any questions.
Pavel.
