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 dropped. In this case, if only a few ice ring reflections are picked, one
can manually Pick(Remove) reflections also.
Good luck,
Jeff
