[phenixbb] Partially occupied SO4 and waters

[Pavel Afonine]

Hi Chris,

yes, you can do it in phenix.refine. Use constrained groups for this:

and do not forget to assign proper altloc identifiers for involved atoms 
(so they don't get pushed apart by non-bonded term).

Please let me know if you have any questions or problems with this.

Pavel.
