C-beta outliers
by Andrea Smith 14 Jun '24

14 Jun '24

Hi all, I am running Phenix v. 1.20.1-4487 on Windows and I keep on getting C-beta outliers of methionine residues after phenix.refine (happened in different data from two different proteins). Even if I correct the methionines in Coot (and they fit perfectly in the density), I get the outliers at the end of refinement again (while these outliers don't fit the density and I can see a green difference map where the C-beta is). Why is this? Is there a way to tell phenix.refine not to move a specific amino acid during refinement? Thanks, Andrea

Help with Phenix/Rosetta Interface Installation
by Lucas Souza 14 Jun '24

Dear all, I have been trying to install rosetta (both release 371 and 20221.16.61629)/phenix (1.21.1-5286) interface in Ubuntu 24.04, but with no success at all. Both Rosetta installation and "rosetta.build_phenix_interface" ends up with no erros. But, when I run "rosetta.run_tests" or try to "phenix.rosetta_refine" I always get the error below: ------- /Generating 2 models on 1 processors... / /DEBUG dumping error message ERROR: Rosetta exited with status 139 stderr output: AN INTERNAL ERROR HAS OCCURED. PLEASE SEE THE CONTENTS OF ROSETTA_CRASH.log FOR DETAILS. Segmentation fault (core dumped) Traceback (most recent call last): File "/home/lucas/pckg/phenix-1.21.1-5286/build/../modules/phenix/phenix/command_line/rosetta_refine.py", line 315, in <module> run(sys.argv[1:], create_dir=True) File "/home/lucas/pckg/phenix-1.21.1-5286/build/../modules/phenix/phenix/command_line/rosetta_refine.py", line 198, in run debug=params.output.debug) File "/home/lucas/pckg/phenix-1.21.1-5286/modules/phenix/phenix/rosetta/refine.py", line 329, in __init__ self.run_jobs() File "/home/lucas/pckg/phenix-1.21.1-5286/modules/phenix/phenix/rosetta/refine.py", line 403, in run_jobs check_result(result) File "/home/lucas/pckg/phenix-1.21.1-5286/modules/phenix/phenix/rosetta/refine.py", line 394, in check_result raise RuntimeError("Aborted due to error in job %d." % result.job_id) RuntimeError: Aborted due to error in job 1./ /Something tells me this is related to the drop of support to Python2 in the new Ubuntu release, but I could not figure out what exactly is the issue. I uploaded both stdout and ROSETTA_CRASH.log in this email./ ------- If anyone can help me with this issue, I would be very happy. Thank you all! Lucas

ADP-BEF-link.cif
by Heidi Schubert 10 Jun '24

10 Jun '24

Hi AAA ATPase modelers Could anyone send me the .cif file to define the link between ADP and a BeFx ion? I’m hoping this has not only the revised angle/bond info between O3B and Be but also the new angle between the Be and Fs different from the planar simple ion. AND, for my hexamer I assume the apply_link.def file then just reads with repetitive 5-line groups: refinement.pdb_interpretation.apply_cif_link { data_link = ADP-BEF residue_selection_1 = chain A and resname ADP and resseq 901 residue_selection_2 = chain A and resname BEF and resseq 902 } Where I change out the chain name but keep calling them residues_selection1 and 2? Many thanks Heidi Heidi Schubert Research Professor Department of Biochemistry University of Utah Rm 116 BPRB 20 S 2030 E Salt Lake City, UT 84112 heidi(a)biochem.utah.edu<mailto:[email protected]> 801-585-9776
