 Dear All.

Is there any disadvantage of using the anomalous data set to do refinement?

I recently solved a structure using Se-SAD.  The anomalous data set was used
in refinement with CNS. It gives decent result. Because traditionaly, after
phasing we will use the nonanomalous data set in refinement. I am just
curious if anybody has tried using the anomalous one and what's the
difference between using anomalous and nonanomalous data in refinement..


Thank You
