[phenixbb] composite omit map problem

Hi,
I am having trouble generating a composite omit map using the
AutoBuild GUI. I am using Phenix version 1.7-650 on Ubuntu and I am
able to run AutoBuild to make a simulated annealing composite omit map
using my experimental data .mtz file and a reasonably refined model
(R/R-free of 24/29% at 3.3 Angstrom). However, when I load the map -
resolve_composite_map.mtz - into Coot (version 0.6.1) along with the
starting model it looks terrible. There is quite a bit of density
between each molecule within the ASU but very little density
surrounding the model itself. However, I am able to open any of the
.mtz_OMIT_REGION_XX files and they look really good.
Any suggestions?
Thanks,
