new Linux installers
by Nathaniel Echols 05 Dec '13

05 Dec '13

Hi Linux/Phenix users-- We are now building installers on several "new" platforms, including Ubuntu 10.04 and several versions of CentOS (which isn't much different from Fedora, except that it's supported by the virtual machine software we're using). Since we don't actually run these OSes outside of the VMs, we're going to crowd-source the testing a little more than usual. Our goal is to retire our ancient Fedora 3 systems - these are old and slow and take up too much space, but it's also the most compatible with other distributions. I'm hoping that the CentOS 5 builds will be a suitable replacement, or perhaps CentOS 4 (but we can only build the 32-bit installer on that OS). In addition to Ubuntu, I'm particularly interested in hearing whether any of these builds runs smoothly on SuSE and Debian. The virtual machine software supposedly supports these OSes too but I haven't yet managed to install SuSE on it after several attempts. The latest builds are here: https://www.phenix-online.org/download/phenix/nightly/?version=dev-1558&sho… We're missing the 64-bit CentOS 5 build right now, but I hope to get that working in the next few days. thanks, Nat

Re: [phenixbb] reduce hangs
by Andreas Förster 05 Dec '13

05 Dec '13

Dear all, I'm not sure how much of my conversation with Jeff Headd and the comments from others that I received made it onto the mailing list. The problem with reduce being stuck in an infinite loop and refinement never completing has now a workaround, if no solution: Mark van Raaij pointed out that running refinement repeatedly while varying the number of cores would eventually avoid the infinite loop. I didn't observe that, but while running refinement with a handful of Xeons got stuck, running the same job with the same executable on the same OS with a bucketful of Opterons instead succeeded. As I said, there's no solution but a number of ways to get unstuck if you find yourself in the same situation like Mark and me. Best. Andreas -------- Original Message -------- Subject: Re: [phenixbb] reduce hangs Date: Wed, 4 Dec 2013 09:46:20 -0500 From: Jeff Headd <jjheadd(a)lbl.gov> To: Andreas Förster <docandreas(a)gmail.com> If the different machine is a slightly different architecture it's possible that it may run, even under the same OS version. My guess is that it's down to slight floating point differences in the coordinates throughout the course of refinement, but it's so hard to pinpoint. If you have access to other machines it is probably worth trying. <snip> Jeff

Coot not allowing real space refinement when connected to phenix
by Jobichen Chacko 04 Dec '13

04 Dec '13

Dear All, I recently upgraded to latest version of coot (version0.7.2). When I try to do the Real space refine zone option, coot is giving the following complaint (Refinement setup failure. Failed to find restraints for PROLYSILE). But it works fine when I open coot separately from a terminal and read the pdb and mtz file. I downloaded this coot along with the ccp4 package and it also works fine when I open from ccp4 interface. Any suggestions will be much appreciated. Jobi

reduce hangs
by Andreas Förster 03 Dec '13

03 Dec '13

Dear all, I'm refining a structure with 11 molecules in the asymmetric unit. Recently I took out NCS (data are to 2.2A and differences between molecules of interest). Refinement now stalls halfway through with two reduce jobs running at 100% CPU. The current job has been sitting like this for four days. The last entry in the log file are a few XYZ individual lines. Refinement includes XYZ, TLS, individual B, weight optimization. I launched 8 cycles. Phenix hangs after 4_bss. I've observed this twice in a row. Any suggestions to overcome this, short of going back to using NCS? This is with Phenix dev-1538 on RHEL 6.3. Thanks.

AutoSol/Heavy atom sites/outside the model
by Egor Tchesnokov 03 Dec '13

03 Dec '13

Thank you for the feedback. WinCoot 0.7/Draw/Cell Symmetry brings up "Show Symmetry" window, which only allows to alter the display but not to coincide the heavy atom sites with the model. Am I not looking at the right menu in Coot ? Thank you for your time and help. Egor

Autobuild combine
by Heather L Condurso 02 Dec '13

02 Dec '13

Hi all, I am still having issues with Autobuild giving errors during the combine step. I've downloaded the latest build and hope that will solve the problem, but in the mean time I'm having an issue trying to combine the models. I've been following the script: #!/bin/csh -f #COMBINE_MODELS SCRIPT if (-d PDS || -d AutoBuild_run_1_) then echo "Please run in a directory without PDS or AutoBuild_run_1_" exit 1 endif echo "Setting up combine models with a dummy run. NOTE: multiple_models_group_number must be correct" phenix.autobuild fobs.mtz multiple_models=true seq_file=seq.dat combine_only=true multiple_models_group_number=2 multiple_models_number=1 > dummy_autobuild.log echo "Copying files to AutoBuild_run_1_/MULTIPLE_MODELS" mkdir AutoBuild_run_1_/MULTIPLE_MODELS cp coords1.pdb AutoBuild_run_1_/MULTIPLE_MODELS/initial_model.pdb_1_1 cp coords2.pdb AutoBuild_run_1_/MULTIPLE_MODELS/initial_model.pdb_1_2 cp map_coeffs_1.mtz AutoBuild_run_1_/MULTIPLE_MODELS/initial_model.mtz_1_1 cp map_coeffs_2.mtz AutoBuild_run_1_/MULTIPLE_MODELS/initial_model.mtz_1_2 ls AutoBuild_run_1_/MULTIPLE_MODELS/ echo "Running autobuild to combine files in AutoBuild_run_1_/MULTIPLE_MODELS" phenix.autobuild combine_only=true seq_file=seq.dat carry_on=true run=1 > autobuild_combine.log # END OF COMBINE_MODELS SCRIPT # Here are the two log files. I used the expl_fobs_phases_freeR_flags.mtz as fobs.mtz and changed each overall_best.pdb and overall_best_refine_map_coeffs.mtz as the model and map to combine. Thanks, Heather

AutoSol/Heavy atom sites/outside the model
by Egor Tchesnokov 02 Dec '13

02 Dec '13

Hello, Level: beginner 1. Data collected at wavelength of 0.9537 2. Ran Xtriage: anomalous data seem to extend to 2.2 A 3. Ran Phaser-MR to get partial model (1 copy in AU) 4. Ran AutoSol using partial model and anomalous data AutoSol finds heavy atom sites (FOM=0.69; Overall score=75.6+/-3.3). Coot displays model/density without heavy atoms Heavy atoms are displayed outside the model (using zoom out). Question: what did I do wrong? Thank you for your time and help. Egor

Red patches of electron density
by Singh, Bishal 01 Dec '13

01 Dec '13

Hi, I am solving a crystal structure at 1.2 Å with completeness 97.3% in the highest resolution shell. There are few small patches of red electron densities on the main chain of a flexible loop at a contour level of ~3sigma of difference ED map. Refinement parameters were following: XYZ coordinates, individual B-factor, optimize X-ray/stereochemistry weight, optimize X-ray/ADP weight and individual Anisotropic ADP for amino acids excluding hydrogen. Target weights are as default in phenix.refine. I already have observed two alternative conformation for this region in another crystal structure. Therefore I am thinking that these red patches are because of lower occupancy of these residues. Please suggest me what shall I do. I shall be grateful for your words. With regards, Bishal Singh University of Heidelberg, Germany
