My immediate reaction while Pavel looks into it is to set all the B-factors
to 20 and refine.
Cheers

Dear all,
I am encountering issues related to B-factors and ADP refinement in Phenix and would appreciate any insights or suggestions. I am currently working on my first PDB file, but I've noticed that many atoms in the PDB file have a B-factor of 0. As far as I understand, B-factor values are calculated by ADP refinement in Phenix real-space refinement, but even after running real-space refinement (with ADP on in refinement settings), the B-factor remains 0 for many atoms. I am currently using Phenix 1.20 on Windows (Newest version available on window). I also attempted to run Phenix 1.21 on a Linux in other computer, but when ADP refinement is enabled, the process starts normally but halts during the ADP refinement step. So I couldn't test whether the issue is fixed in the newest version.
Aside from the B-factor issue, I am also experiencing an inssue related to ADP refinement:
When I run real-space refinement with ADP refinement enabled, the process starts normally but halts during the ADP refinement step. According to the log file, other refinement steps proceed without issues, but it fails to progress at the ADP refinement stage. Additionally, when I try to pause the process, I receive a "NoSuchProcess" error, so ADP refinement process may have unexpectedly terminated.
At first, I thought it's the issue related to system performance or hardware differences, because adp refinement with this pdb file and identical parameters works on some computer but fails on others (the same version of Phenix). Still it's weird because this issue has occurred unexpectedly, as ADP refinement previously worked in my computer under the same conditions without any problems and also other PDB files run without any problems in my computer.
I would appreciate any insights or suggestions on how to resolve this. Thanks _______________________________________________ phenixbb mailing list -- [email protected] To unsubscribe send an email to [email protected] Unsubscribe: phenixbb-leave@%(host_name)s
