Hello again. I agree the get-around strategy we took is not a good practice at all. For our initial imosflm run we actually turned on 'exclude ice ring' button. The following was reported in the log: ICE RING SUMMARY: reso ice_ring mean_I mean_Sigma Estimated_I Ratio Zscore Completeness A

There is an option in xds to exclude typical ice ring regions. It was usually in the XDS.INP but commented out by default. That should work as it should work with the ice ring button in mosflm. Cheers Christian On Tue, Apr 9, 2019 at 11:07 AM Harry Powell < 193323b1e616-dmarc-requ...@jiscmail

Hi SamDid you use the ice-ring exclusion option in iMosflm (a button that has an image like a snowflake)? It should exclude data in _narrow_ resolution rings (substantially less than 0.2Å!) around the ice rings, and can be set for any combination of indexing, refinement and integration. There shoul

Hello everyone Thanks a lot for your input and advices. To report on how we tackled the issue - (1) We used imosflm to integrate the data. (2) We eventually integrated the data in two resolution ranges, say 45A-3.5A, and 3.3A-3A, and merge them by Aimless. I must add that indeed from the log file

Dear all, And if you want to process with XDS: autoPROC [1] will try to detect and exclude ice-rings automatically - if present [2]. If you know that you have ice-rings you can force it [3] to exclude all known ice-rings ranges - but this might not be the best solution if you have "just" diffuse

Dear Sam, to continue from James Parkhurst's email... You can do more analysis regarding ice rings using Auspex (https://www.auspex.de/) if you already have some integrated file. Regarding re-integrating images, what did you use the first time round? I think if you use DIALS it got some clev
