[phenixbb] An easier explanation of the regions in omit map

So I have quite a few regions build by the SA_omit map of phenix. But How do
I go about looking at these maps. What am I looking for here. Should I look
at the regions where the occupancy was set zero in all these outputs and
find if I could build some thing from one of the maps? I guess I am asking,
How do I use this information to move forward in refinement? There are 24
regions map and .pdb output in the /OMIT directory.
