[phenixbb] Combining phases?

Dear All,

Im struggling with a structure. I have a good native data set with 
resolution 2.1A and a data set with ok stats collect at low energy 
trying to extract some anomalous signal from intrinsic sulphur atoms 
(6/ASU/400aa).
Using a model of one of the domains I got a MolRep solution that has 
somewhat convincing features in the electron density maps some portions 
of the structure but not in others. I also ran HySS and obtained some 
coordinates for the 6 sulphur atoms but the map here is uninterpretable. 
Xtriage suggests the anomalous is only good until about 8A so I am not 
that surprised.

Is there any way I can try to combine my putative MolRep model and 
phases with the sulphur anomlaous signal and maybe get better maps to 
build into?
If so, how would I do that using PHENIX?

thanks for the help
