[ccp4bb] reifine metal with phenix

[Lisa Wang]

Hi all,
 The resolution of my structure is 3.1A. There are three Mg binds in this
structure. I try to refine it with phenix. There are cleare extrea density
before I add Mg atoms. But when I put Mg in the central of density with good
coordination and try to refine it by phenix, those Mg move away.Does phenix
need addiational paramters file to refine Mg and keedp it 2.1A   2.1A from
it coordinated atom?
 Thanks.
Lisa
