labelit access in Phenix?
by Keller, Jacob 03 Jul '15

03 Jul '15

Dear Phenix list, Does anyone know how to access labelit through Phenix to determine whether the highest possible symmetry has been found? I exclusively use the GUI, and it's on win7. In the labelit documentation/homepage it mentions the command: labelit.check_pdb_symmetry [pdb coordinate file] [data=mtz file] But I did not find any executables called labelit, nor can I figure out how to run Phenix from command line in Win7, short of installing Cygwin or something.

metal refinement: adps and restraints
by Alexandra Marques 02 Jul '15

02 Jul '15

Hi, I am refining a protein with a Mo in the active site and which is bound to a cofactor and to a water molecule. After each refinement step there is always a lot of positive and negative density around the Mo and the cofactor molecules, although their occupancy refined to 1. I read this message http://www.phenix-online.org/pipermail/phenixbb/2015-May/022031.html, but I still have doubts about how to choose the refinement parameters. I know I have to select the Mo atoms to be refined anisotropically. And the other atoms, do I have to specifically select them to be refined isotropically?. For instance: Isotropic atoms: not element Mo Anisotropic atoms: element Mo I am asking that because I have been using TLS for the protein atoms during refinement, so I am not sure if it is correct to select the other atoms as isotropic or if I leave it in blank… My other problem is with the metal restraints. I am not sure about the ideal distance between the Mo and O atom but based on homologous protein structures I choose the following: refinement.geometry_restraints.edits { bond { action = *add atom_selection_1 = name MO and chain A and resname 4MO and resseq 1 atom_selection_2 = name O and chain A and resname O and resseq 2 distance_ideal = 1.900000 sigma = 0.050 } } However after the refinement this ideal distance interval (1.95-1.85) is not respected; I have 4 active sites and in some of them the Mo-O distance refines to 0.83 A although there is a lot of density for the water molecule to be at 1.9 A. How to make the restrainst work? Am I missing something? Thank you very much, Alexandra

accept MR solution even if the number of clashes is above the threshold
by Almudena Ponce Salvatierra 02 Jul '15

02 Jul '15

Hi everyone, I am running Phaser (from Phenix) and while checking the .log file (it is still running) I realize that it found some solutions with a TFZ score over 7, but it won't take them I guess because the number of clashes is higher than allowed (>12, I guess they're not so many either). My models are poor and for so I would like to check these solutions that for now Phaser will reject. However in the input I don't want to increase the allowed number of clashes because this will then affect all the other solutions and this will take forever... So my question is: can I tell phaser somehow to write down/save the solutions for which the TFZ score will be higher than 7? Even though the clashes Thanks a lot in advance All the best, Almu -- Almudena Ponce-Salvatierra Macromolecular crystallography and Nucleic acid chemistry Max Planck Institute for Biophysical Chemistry Am Fassberg 11 37077 Göttingen Germany

C-beta RMSD

Hi, Is there a tool which can calculate C-beta RMSD for equivalent amino acids of homologous structures, post C-alpha superposition? Sorry if its off topic, Thanks, Kaushik -- Stupidity is everyone’s birthright. However, only the learned exercise it! --Kaushik (28Oct2014)

Simulated annealing refinement for just one domain
by Appu kumar 30 Jun '15

30 Jun '15

Hello All, I was wondering if there is a simulated annealing refinement for the just one domain and keeping the other domain fix. I have a structure where the electron density is poorly defined which could be because of the some conformation of domain is different. Although the resolution of the data is 4A but channel has well defined density in the TM domain. Thanks in advance for your advice and suggestions. Appu

This should have been forward to the mailing list. Rob -------- Original Message -------- Subject: Re: [phenixbb] labelit access in Phenix? Date: 2015-06-26 21:46 From: "R.D. Oeffner" <rdo20(a)cam.ac.uk> To: "Keller, Jacob" <kellerj(a)janelia.hhmi.org> Copy: Aaron Brewster <asbrewster(a)lbl.gov>, Nigel W Moriarty <NWMoriarty(a)lbl.gov> Hi Jacob, Labelit is not present on Windows in the last official release of Phenix from May last year, version 1.9-1692. But it is present in recent pre-releases of Phenix as command line tools. When you install Phenix on Windows a startup group is created that includes a command line prompt which recognises Phenix commands. From there you can execute all labelit command line tools. I think Nigel is about to put the recent Windows pre-release online on the Phenix website. Feel free to get in touch with further questions.

phenix-1.9-1692 pymol problem
by ChenWeiFei 27 Jun '15

Dear all, I just install phenix and I found phenix-1.9-1692/pymol/install and it says: INSTALLATION of the PyMOL Executable Build for Unix 1) Extract the appropriate archive. tar -zxvf pymol-0_99-bin-linux-x86-glibc23.tgz 2) Change directory into the root level of the archive. cd pymol 3) Run "./setup.sh" which will create "./pymol" with a record of the current working directory. ./setup.sh 4) Link or copy ./pymol into a directory that is in your path. ln -s `pwd`/pymol /usr/local/bin/pymol (or perhaps) cp pymol /usr/local/bin/pymol 5) Now try it! ./pymol I follow it and when I type pymol there comes an error: $ pymol /usr/local/bin/pymol: /usr/local/phenix-1.9-1692/pymol/pymol.exe: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory Is any one konw how to deal with it?

phenix.composite_omit_map
by Dyda 26 Jun '15

26 Jun '15

Dear Phenix list, I have generated an mtz file with phenix.composite_omit_map. It has labels assigned as 2mFo-DFC for F and PH2mFo-DFC for P. Now, I would like to generate a map file. I was trying to convince phenix.maps to use this mtz file to do that, however it didn't seem to like the labels. I tried both the GUI interface of phenix.maps and also tried to force feed it through the command line with a maps.param file. Neither of these worked, so I'm obviously missing something. Btw., Coot can open the mtz file and display the map, and it does look reasonable. This is phenix-1.9-1692 running under RHEL6. Thank you for your help.
