[phenixbb] occupancy refinement question

[Pavel Afonine]

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.
