But that wouldn’t incorporate other useful information, such as percentage completeness in the outer shell and whether inclusion of the reflections in the outer shell for refinement actually effects the resulting structural model and map to a significant degree. Diana

Can we get some momentum for the "standard table 1" including TWO numbers - outer limit used in refinement, and nominal resolution based on some standard such as I/sigI =2 (or 3, or whatever the community can agree on)? That would hopefully cut down on all the reviewer complaints of overstated

Hi Dusan, I don't know what the correct answer is but I think it is safe to see that your referee has outdated views (trying to stay polite here). I/sigI > 2.0 with decent completeness would be not be seen as to agressive by most (but as too conservative by others!). From that cut-off you

Hi Dusan, I am pretty sure "It is well accepted that the criteria for resolution cutoff should consider both I/SigI and Rmerge for the outer most shell. For data sets collected at synchrotron sources, the criteria of I/SigI > 5 and Rmerge <50% can be taken as a good practical reference.” has

Hi, Browsing through the recent discussion on EM data resolution cutoff it occurred to me that the X-ray diffraction community isn’t that unanimous either. My stand: When the default resolution cutoff provided with the data processing software in electron density map calculation and
