[phenixbb] Question about overall_best history

Hi,

Thank you for the e-mail.

It makes sense; I was thrown off by the fact that my MAP CCs for all
solutions are all so close but the FOM for the top scoring solution is much
lower (by about 0.1 overall, and by ~0.25 in the highest resol. shell) when
compared to the second top scoring solution. This probably relates to the
fact the the anomalous signal isn't too great beyond 4.5 while I'm trying to
phase beyond that, and that I'm using Ta for a TaBr cluster.

Which reminds me, how come when I phase using Ta instead of a TaBr cluster
the occupanies and B-factors don't blow up in SOLVE?

Thanks again!
