One can try to set the high resolution to exlude the ice ring ONLY during autoindexing. Once Denzo picks the correct lattice, then you can include the highest resolution available during the refinement. or One can pick "fewer peaks" during the peak search in hope that the ice ring will be droppe

[ccp4bb] CNS error message with MR
