I tried to calculate a composite omit map in autobuild for 3 complexes in the au. The calculation finished without any problems, but the maps look not right. There is density for the molecule, but there is a lot of density in the solvent areas, which I never saw when I calculated regular 2fo-fc maps or fo-fc maps. I also have calculated omit maps in autobuild before for single problem region and never saw anything like this. Any idea what could have gone wrong? Where should I start looking?
