Hi, because of an update to Sonoma, I also had to update to Phenix 1.21.1-5286-000. When I'm running phenix.refine from the GUI, use an MTZ with resolution e.g. from 1.65 - 51A, use "High resolution" and "Low resolution" to refine against a specific range of data, phenix.refine does not cut off the data beyond the limits set there, but instead takes all of the data. For sure, I cut the MTZ before, but many times it is about trying out which data to include and not include and this is not really how it should be... Is this known? Is there any way to solve this issue? Thanks!
