Hi Fred,
by default phenix.composite_omit_map does not do any refinement
(omit_type=simple) and it computes composite OMIT map as described in
Figure 6 here:
http://journals.iucr.org/d/issues/2015/03/00/lv5075/lv5075.pdf
Optionally, you can ask it to do refinement with (omit_type=anneal) or
without (omit_type=simple) Simulated annealing.
You don't have control over refinement that happens in
phenix.composite_omit_map.
I don't think it's important though.. The goal of running
phenix.composite_omit_map is not to get the best refined model but to
answer questions that OMIT map is helpful at. I doubt that imperfect
geometry of secondary structure that may come out of refinement without
specific restraints is going to impact the utility of OMIT map.
All the best,
Pavel
