Hi phenixbb,

I'm trying to understand the current status of joint X-ray/neutron refinement in phenix.refine. The announcement of the latest release mentions a change in the algorithm as described in the recent publication. In the documentation:

<https://phenix-online.org/documentation/reference/refinement.html#neutron-and-joint-x-ray-and-neutron-refinement>
Structure refinement in PHENIX<https://phenix-online.org/documentation/reference/refinement.html#neutron-and-joint-x-ray-and-neutron-refinement>
phenix-online.org<https://phenix-online.org/documentation/reference/refinement.html#neutron-and-joint-x-ray-and-neutron-refinement>
        [X] <https://phenix-online.org/documentation/reference/refinement.html#neutron-and-joint-x-ray-and-neutron-refinement>


it's described how you can run joint refinement using a parameter file. Does this mean that it is *only* possible in this way and not through the GUI? The GUI was very useful in the past as it automatically opened Coot with the maps for both X-rays and neutrons, and the refinement statistics for both were displayed in the GUI. As far as I can see joint refinement via the GUI last worked in version 1.19.2-4148 from 2021.

Best regards
Derek
