Hardware migration
by Billy Poon 19 Jun '24

19 Jun '24

Hi everyone, We are in the process of migrating these bulletin boards to new hardware over the next few weeks. I will make another post once the migration is completed. Nothing will be changed until then. Thanks! -- Billy K.

high and low resolution in Phenix 1.21.1-5286-000
by Dominik Oberthuer 30 May '24

30 May '24

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!

Extra map coefficients in 1.21.1-5286
by Dr. Kevin M Jude 24 May '24

24 May '24

In my latest installed version of phenix, I find that additional, redundant map coefficients are being added to the output mtz file. I compare an identical refinement originally run in 1.21rc1_5058 and then repeated in 1.21.1-5286. *_filled and *_4 appear to be redundant, and the final sets of coefficients (*_no_fill and *_5), appear to include the test set reflections, even though I’ve selected Exclude R-free set from map coefficients in the gui. This is a little bit confusing, but primarily an annoyance because auto-open mtz in coot can’t figure out which coefficients to use. 1.21rc1_5058 Col Sort Min Max Num % Mean Mean Resolution Type Column num order Missing complete abs.

NIGMS Mature Synchrotron Program Evaluation
by Paul Adams 21 May '24

21 May '24

Dear Colleagues, Apologies for the US-centric posting, but I think this is of interest to many of the bulletin board subscribers who make use of synchrotron facilities in the US. NIH is seeking feedback on the Mature Synchrotron Program: https://grants.nih.gov/grants/guide/notice-files/NOT-GM-24-019.html This program supports synchrotron-based user resources where the technologies are at an advanced level, including Macromolecular Crystallography, Small-Angle and Wide-Angle X-ray Scattering, fiber diffraction, and other synchrotron-based techniques that generate important data, with an emphasis on structural biology. Responses to the RFI will be accepted through 6/17/2024. All comments will be anonymous and should be submitted electronically via a web form at: https://www.research.net/r/P30_RFI As the Director of one of the resources it has been suggested that I help make the community aware of the RFI, so there is the opportunity to provide feedback in a timely manner. Feel free to pass this on to any of your colleagues who may be interested.

"<" symbol in reflection mmcif status column
by Kreitler, Dale 17 May '24

17 May '24

Looking at some output reflection cif files from phenix.refine I'm wondering what does "<" mean in the status column and why would F_calc_with_sovlent structure factors also be missing for these reflections? In some cases I can see it coincides with unobserved reflections, but this doesn't seem consistent. Any insight or links to documentation that describe these values would be much appreciated.

ADP refinement in phenix.real _space_refine
by Luca Pellegrini 16 May '24

16 May '24

While refining a protein-DNA complex in a cryoEM map (~2.5-7A), I have noticed the following behaviour of ADP refinement: - If NCS is on for the protein chains, no ADP refinement of the DNA takes place. - If NCS is off, ADP refinement behaves oddly: one strand of dsDNA is refined with atomic ADPs, the other strand with group ADPs (one per nucleotide). The group ADPs take up unphysical values (lower ADPs in poor map regions), whereas the atomic ADPs look sensible. - To get the ADP refinement of DNA to behave normally, I need to both leave NCS out and set nproc=1 explicitly (haven’t tried other values). I wonder if any of this has been seen before or am I not doing this correctly?

ligand links
by Heidi Schubert 14 May '24

14 May '24

Hi, Do you think you can link one ligand to two other molecules. (one NON-POLYMER and one peptide). I guess my other option is to create a new ligand. I assumed you pre-deleted the atoms that are supposed to be deleted in the link? I did delete them and it complained and I put them back in and it’s complaining. Pretty similar errors, but I’m wondering if it’s just the second link that’s causing problems. I’ve got files PNS.cif ACE.cif PNS-SER.cif ACE-PNS.cif apply_link_ACE-PNS.def apply_link_PNS-SER.def Heidi [A screenshot of a computer error Description automatically generated]

I have not managed to solve this, regardless of whether I was running the installation command with sudo privileges or as root. For context, I successfully installed Phenix 1.20 on the same machine and same distribution 6 months ago, but had to reinstall everything since and it does not work anymore now. Have you heard of such an error? Do you have a hint on how to fix it?

Hi All, I hope someone from Molprobity end reads CCP4 mailing list where people report issues with Molprobity (server and from within Phenix). Just in case this needs someone's attention. Pavel
