Transferring Phenix home
by csteussy 18 Mar '20

18 Mar '20

All, In this age of self quarantine I have moved a number of my PHENIX projects home. All the working subdirectories have a .phenix entry. Is there a way to incorporate the history of the projects from work to my home installation. Starting the GUI shows none of it. Both of these are Ubuntu 18.04 and I have sudo privileges. Thanks in advance. Nic out

Dear Colleagues, with the effects of COVID-19 being felt worldwide, we all want to do something to help. There are several teams that are using crystallography and cryo-EM to help develop diagnostics and therapeutics for the virus. We wanted to let you know that the members of the Phenix team stand ready to assist with the analysis of COVID-19 related data should that be helpful to you. Please feel free to contact any of us.

Slurm/qsub queue usage
by Michael Weyand 18 Mar '20

18 Mar '20

Dear Phenixer, I would like to use Phenix GUI queue execution option. We have access to cluster nodes via Slurm/qsub. https://slurm.schedmd.com/documentation.html The reason is that we have severe problems to run Coot/PyMol form the Phenix GUI if Phenix is executed on our number cruncher. This direct Coot usage GUI option is HIGHLY preferred by my young colleagues... Therefore my Slurm queue installation. But I have no clue how to add the needed first qsub script line ( "#!/bin/bash" or "#!/bin/tcsh" ) to the final Phenix command script from the Phenix GUI, which is to my knowledge a must for the qsub/sbatch command. Same holds true for the CCP4i GUI ... :-( This line is added to avoid cross positing to CCP4BB ... ;-) Is there any simple hint / command which I have missed ? Kind regards, Michael

crash when running PDB Tools job in 1.18rc4
by Daniel Larsson 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.
