Dear Mona,
Yes. You can get Denzo to reject reflections on or close to ice rings, or
any other features with highly irregular background variations, by
increasing the value of the REJECT keyword (see p. 40 of the HKL2000
manual by D. Gerwith,
http://www.hkl-xray.com/hkl_web1/hkl/manual_online.pdf).
Hi
You can exclude the ice rings easily in Mosflm - from the command line -
(a) Autoindexing -
AUTOINDEX EXCLUDE ICE (but see user guide for more on this)
(b) Processing -
RESOLUTION EXCLUDE ICE
Or if you try iMosflm, just check the button that says "exclude ice
rings" (Ind

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
