Dear Mona, If you used XDS to process the data you could use the EXCLUDE_RESOLUTION_RANGE keyword to exactly do what you describe. Best regards, Alexander Mit freundlichen Grüßen / Best regards / Cordialement

I have some lovely diffraction data that has been marred by ice rings (so...not as lovely as it could be). I was told it may be possible to mask the regions of the ice rings (obviously sacrificing completeness) during processing. I have been using HKL2000 to process data. Is this feature available with this program? Otherwise, we also have Mosfilm. Any advice would be greatly appreciated. Thank you.
