Hi Jesse, there was a bug a while ago that we fixed. Are you using the latest Phenix? If not, please try it and if that does not fix the problem we'll take a closer look. All the best!

map-to-model FSC on low resolution map
by bluufive2＠gmail.com 25 May '25

Hello, As part of a reviewer request for our manuscript, we are attempting to generate map-to-model FSCs for two low-resolution cryo-EM reconstructions—one at 10 Å and the other at 20 Å. We’re encountering an issue when using mtriage(both standalone and as part of the comprehensive cryo-EM validation pipeline), where the map-to-model FSC values are reported as “None”. For the 10 Å map, we were able to obtain a valid halfman-halfmap AND map-model FSC by supplying the two half-maps rather than the final unfiltered reconstruction. However, this approach has not worked for the 20 Å map, and we are still unable to retrieve a map-to-model FSC. I initially suspected the issue might be related to masking, but it appears that mtriage does not support the use of a user-provided mask. If you have any insight into what might be causing this or suggestions for alternative approaches, we would greatly appreciate your input. thanks best Jesse Hansen

Excluding atoms from real-space refinement
by elwood.mullins＠vanderbilt.edu 14 May '25

Is it possible to exclude atoms in real-space refinement? Older posts seem to indicate this is, or at least was, only possible in reciprocal-space refinement. Has that changed? Using reference restraints as an alternative is less than optimal. Any help would be greatly appreciated.

Dear All We are now at capacity for the Integrative Structural Biology Summer School www.school2025.cristallografia.org<http://www.school2025.cristallografia.org> that will be held in Padua, Italy 7-11 July 2025 However, given the interest we have decided to re-open the registration form as we have been able to secure a slightly larger room for lectures and tutorial. Registration will close this Friday at 5pm CET.
