Recovering Autobuild from tty disconnect
by Francis E Reyes 27 Aug '11

27 Aug '11

Our job submission node disconnects 'idle' after 4 hours of inactivity. As most grid / autobuild jobs take about that long I end being disconnected while the grid jobs complete. [1] Screen is not an option since access to the job submission node is via a load balancer and none of the job submission nodes allow access unless you're coming from the load balancer . i.e. there's no way to get to original machine where your screen has been started [2] all processes are sent SIGKILL during this automatic logout preventing the use of nohup.. will background=True work? [3] In the meantime, is it possible to resurrect the current autobuild? I've got FINISHED in all the autobuild's submitted to the grid, but everytime I try to combine_only=True run=my_run_number, I start from the beginning (with submitting the autobuild jobs to the cluster) even when I've moved the best of each build into MULTIPLE_MODELS.

Dealing with malformed ligand geometries in phenix.refine
by Francis E Reyes 26 Aug '11

26 Aug '11

Hi all I've got 3.0A data and I'm ending up with distorted ligand geometry in phenix.refine. The model is complete and fitting the ligand is the final step (refined with individual_sites and individual_sites_real_space as suggested by an earlier posting). I've tried with a wxc_scale of 0.001 and it still looks wonky (tetrahedral C's not being so, etc). My cif is coming from phenix's internal db. Any suggestions?

unstable phenix?
by Kenneth A. Satyshur 25 Aug '11

25 Aug '11

We are running phenix (743) on a RHEL5 dual quad, multithread, making a composite omit map pf a very large structure (750 AA) and the system keeps getting locked up. Have anyone else seen this type of problem? Does multiprocessing work well on RHEL or just FC versions? We needed to install the FC8 version (/phenix-1.7.1-743/build/intel-linux-2.6-x86_64) to get it to work. So maybe we are using the wrong version? Shoiuld I recompile it for our system? Why is the gui always open when we are running long jobs (many days)? We need to put this stuff in the background and log out so someone else can run. Should scripts be used instead of the gui? Great program but too unstable. kas -- Kenneth A. Satyshur, M.S.,Ph.D. Associate Scientist University of Wisconsin Madison, Wisconsin 53706 608-215-5207

Weird Hydorgen refinement
by Yuri 23 Aug '11

Hi guys, I DEFINETELY ran refinement after I removed the hydrogens. My Rfree went up from 0.159 to about 0.167. Thanks for the tips. Ill give pdb.tools a try... -- Yuri Pompeu

Reference model restraints in autobuild?
by Francis E Reyes 23 Aug '11

23 Aug '11

Hi all While it is possible to generate refinement parameters to pass into autobuild, how does one pass the reference structure into the autobuild jobs if one were to refine using geometry restraints from the reference structure? (command line autobuild) If I can't supply the reference pdb, is there a phenix cmd utility that'll spit out all the restraints given a pdb so I can supply them in the refinement parameters file?

Re: [phenixbb] Weird Hydorgen refinement
by Yuri 23 Aug '11

23 Aug '11

Hi Pavel, The pdb did have anisou records for H's. I believe that is because in some previous runs I had only selected chain 'A' - I left out "and not elemnt H" - which I believe caused the H's to get refined anisotropically. I am trying to get rid of the ANISOU records and Ill run refinement again. ps. I am getting ready to deposit the coordinates and I dont want to keep hydrogens in the model, how can I get rid of them? I ve been using pyMol to remove them, but pymol gets rid of all the info -including symmetry -that phenix adds... Thanks -- Yuri Pompeu

Weird Hydorgen refinement
by Yuri 23 Aug '11

23 Aug '11

Hello everyone. I was trying to refine my model anisotropically. I selected element NA or (chain A and not element H). I looked at the output pdb shows that hydrogens were being refined anisou as well as the protein. I believe its because technically they are also in chain A, but shouldnt the default be never refine H's anisotropically, especially at 1.5A ?. -- Yuri Pompeu

Hi all I downloaded the Phenix developing version 842, autosol gui running gave me the following error, "The key gui_output_dir is not in var_type_dict....command line wizzard needs conversion in the autosol.py script uing translating inputs or else in excluded inputs....wizard setVars routine needs this variable set". I have not had this error earlier version. any help? Thanks ram
