crash when running PDB Tools job in 1.18rc4
by Daniel Larsson 18 Mar '20

18 Mar '20

Just want to report a bug in the latest release candidate. I just installed it and when I try to open an old PDB Tools job or start a new one, the GUI crashes without any error message. The same thing works fine with 1.18rc1. I’m using macOS 10.14.6 (Mojave).

The ? in the column from 1.17 is a consequence of some changes we had made to the code and we're working on fixing that. The secondary structure issue with Chimera is separate since that column is for matching the protein chain with the sequence, not as a way to annotate secondary structure. We are working with the wwPDB to make sure our output is in compliance with the latest mmCIF dictionary. Let us know if you have any other questions. Thanks! -- Billy K.

phenix.geometry_minimization with amber option
by Wei Wang 12 Mar '20

12 Mar '20

Dear all, I try to use phenix.geometry_minimization with amber option, but when reaching minimization step, the function always crash. If I don’t use amber option, then it’s ok. The commands I put in was like: phenix.geometry_minimization 4phenix_xyz.pdb amber.use_amber=true amber.topology_file_name=4amber_xyz.prmtop amber.coordinate_file_name=4amber_xyz.rst7 amber.order_file_name=4amber_xyz.order I tried both 1.17 stable and latest overnight build. Please share your advice, thx! Wei

prepare_pdb_deposition produce incomplete results in version 1.17
by Marta Martinez 09 Mar '20

09 Mar '20

Hi, In the past (phenix version 1.13) we have been using prepare_pdb_deposition to generate CIF files of atomic structures. In the last version (1.17) the program produces an incomplete output if the input is a PDB file. The tests have been carried out with the protein hemoglobin (PDB ID = 5ni1). If we downloaded it from the PDB databank we get the file 5ni1.cif. If we "export" 5ci1.cif using prepare_pdb_deposition the result is correct. On the other hand, if we convert 5ci1.cif to PDB either using chimera uscf or maxit (https://sw-tools.rcsb.org/apps/MAXIT/index.html) and then we execute prepare_pdb_deposition, one of the columns (label name = _atom_site.label_entity_id) is filled with the symbol "?" instead of the label_entity_id (as the version 1.13 did). One of the effects of this misbehavior is that chimera displays the file as a set of aminoacids with no connection between them (no secondary structure is shown) A few lines of the file obtained using phenix 1.17: ATOM 1 N . VAL A 1 ? 45.71600 55.72700 67.16700 1.000 80.64000 N ? A ? 1 1 ATOM 2 CA . VAL A 1 ? 46.41500 54.48900 67.60900 1.000 80.57000 C ? A ? 1 1 ATOM 3 C . VAL A 1 ? 45.42800 53.30800 67.68900 1.000 75.67000 C ? A ? 1 1 Corresponding lines of the equivalent file obtained using phenix 1.13 ATOM 1 N . VAL A 1 ? 45.71600 55.72700 67.16700 1.000 80.64000 N ? A 1 1 1 ATOM 2 CA . VAL A 1 ? 46.41500 54.48900 67.60900 1.000 80.57000 C ? A 1 1 1 ATOM 3 C . VAL A 1 ? 45.42800 53.30800 67.68900 1.000 75.67000 C ? A 1 1 1 Note the difference in the ante-penultimate column. We would appreciate if phenix 1.17 is modified so the column _atom_site.label_entity_id is filled with the proper chain ID. best wishes -- Marta Martinez Gonzalez Biocomputing Unit (Lab B13) National Center for Biotechnology-CSIC Darwin, 3.

Real-space refinement fails to restrain CYS SG ZN properly
by Aaron Oakley 03 Mar '20

03 Mar '20

I'm trying to refine a structure containing ZN bound to four cysteine residues. I have had trouble with Real-space refinement mangling the residues around this ZN. At first, Real-space refinement tried to turn the cysteine into disulfides. I tried switching this off with… resname CYS and name SG …in the disulphide bond exclusion selection string under the Model interpretation menu (there are no disulfides in the protein). But the cysteine-zinc cluster continued to be mangled. Inspection of the .geo file shows that the SG-ZN distance is being restrained, but the CB–SG–ZN angle is not. I checked the relevant dictionary file... phenix-1.17.1-3660/modules/chem_data/mon_lib/list/mon_lib_list.cif And the correct bond and angle restraints do seem to be present: . . . ZN-CYS 1 ZN 2 SG single 2.340 0.020 . . . ZN-CYS 1 ZN 2 SG 2 CB 109.000 3.000 . . . Suggestions on how to fix this welcome. –å

Dock in map fails with search map file.
by Aaron Oakley 28 Feb '20

28 Feb '20

Salvete! I am trying to use Dock in map to superimpose one map onto another. The job runs, but fails with PHENIX error: “Job294_sharpened_relion.mrc_as_model_refine_001.pdb" is not a known model type. Inspection of this file suggests that it is indeed a proper PDB file. (The original map I am trying to move is job294_sharpened_relion.mrc). Any solutions? Thanks, –å

real space correlation coefficient from the command line
by Daniel Larsson 25 Feb '20

25 Feb '20

Hi, When running a real-space refine, there is an option in the results to save a text file with real-space correlation coefficients (correlation_coeficients.txt). Is there a way to calculate these numbers from the command line? It would save me a lot of clicking, sinceI have dozens of maps which I want to run in parallel and analyze using scripts.
