Were those examples you computed earlier SA omit? That example looked a lot better than what I usually get. Do you have any pseudomerohedral cases?

It would be better to simply take the last refined model before any ligand was added and use that - but an SA omit map would also be acceptable.  (Experimental density, if you have it, would be even better.)
