Autosol problem: Failed to carry out Autosol_scale_and_analyze_mad
by Zheng Zhou 22 Dec '09

22 Dec '09

Dear all I installed phenix nightly builds, dev-256. I have solved structures using molecular replacement. Phenix.refine runs smoothly. Thanks for your great work. When I run some test data using autosol, I met the following error message: ******************************************************************************** Failed to carry out AutoSol_scale_and_analyze_mad: None of the solve versions worked See overall log file and also solve log file (in AutoSol_run_1_/LAST.LOG) ******************************************************************************** The LAST.LOG appears to be empty. I also run the phenix.solve command. Here is the output: ********************************************************************************************* $ phenix.solve binary=/usr/local/phenix-dev-254/build/intel-linux-2.6/solve_resolve/exe/solve SOLVEDIR=/usr/local/phenix-dev-254/solve_resolve/ext_ref_files SYMOP=/usr/local/phenix-dev-254/solve_resolve/ext_ref_files/symop.lib SYMINFO=/usr/local/phenix-dev-254/solve_resolve/ext_ref_files/syminfo.lib CCP4_OPEN=UNKNOWN SOLVE_RESOLVE_MALLOC_MAX=7.48024e+09 /usr/local/phenix-dev-254/build/intel-linux-2.6/solve_resolve/exe/solve: error while loading shared libraries: /usr/local/phenix-dev-254/build/intel-linux-2.6/lib/libimf.so: cannot restore segment prot after reloc: Permission denied ***************************************************************************************************** The libimf.so file is there.

phenix GUI freezing during refinement and file naming issues
by John Berrisford 22 Dec '09

22 Dec '09

Dear all I've recently been having a few problems with the new phenix GUI freezing during refinement runs on several different systems, most often when I try and do something different on the computer which puts the GUI in the background or on a different desktop. I've seen this problem when running a local copy of phenix on a ubuntu 9.10 system or when running the GUI remotely on a mac connected to our Centos linux cluster. When I switch to a different desktop to get on with doing something else (refine jobs can take a long time) the GUI freezes - although the underlying task runs correctly. The only way out of this problem is to force quit the GUI and then restart it. However, this means that the task isn't recorded in my history and all settings used to run the job are lost from the GUI - the parameter file to run the job does exist though. This also means I lose all the nice molprobibity connections to coot which are really useful. Also if I try to run phenix on the Centos linux cluster when running a local windows system the GUI is so sllloooowwww whenever the GUI tries to open a new window that its unsuable. Has anyone else seen these problems and know a cure? If I run phenix locally on a mac I don't seem to have this problem, but it is nice to run the refine job on our linux cluster so that I can get on with doing something else without it slowing down my mac. On another note, when running phenix refine from the GUI it nicely puts all the files in a folder called "Refine_1" etc... with the number incrementing with each run. So, why are the pdb and mtz file always called "refine_1..." not "refine_2 etc... to match the folder name? This would help with keeping track of files during itterative refinement and model building. It would also stop the problem of having lots of files called "refine_1" loaded into coot when I try to compare models from different refine runs. It would also be useful to be able to be able to add a prefix to the file name / folder name / job name in the GUI so that I could distinguish between different refinement experiments. This is easy to do on the command line....

Re: [phenixbb] ncs resolve
by Thomas C. Terwilliger 18 Dec '09

Hi Georg, I think that if phenix.find_ncs says No NCS found...you might try ncs_in_type=sites then it is interpreting the sites as parts of chains and is trying to find NCS in those chains, while what you want is for it to interpret these as sites and to find ncs in the sites. So I wonder if you did try adding the keyword ncs_in_type as in: phenix.find_ncs my_sites.pdb my_map_coeffs.mtz ncs_in_type=sites If that failed, then I would suggest trying fewer sites that are more separated: perhaps 3 or 4 sites per monomer, as far apart as possible. If that fails (or maybe as your first try actually), take the entire helix, and make 2 copies A and B, placing them in their appropriate places, and then feed these to phenix with: phenix.simple_ncs_from_pdb my_two_copies.pdb and that may do it for you. All the best, Tom T >> Dear phenix users, >> >> luckily autobuild could solve my SAD problem, but didn´t find any NCS. >> Although the protein is a dimer.

queueing systems
by Nathaniel Echols 18 Dec '09

18 Dec '09

Hi all-- I'd like to hear what kinds of queueing systems people are using for running Phenix on managed clusters. The eventual goal - if feasible - is to add support for submitting jobs directly from the Phenix GUI. Anyone who is interested, please send me (not the list) a brief email describing a) the OS, b) the queueing software, and c) the submission method (i.e. shell script, configuration file, simple command). (Also, anyone who is willing to help test this if and when it becomes available, let me know - I have access to Sun Grid Engine and Condor already, but it's probably going to be difficult to test anything else personally.) thanks, Nat -------------------- Nathaniel Echols Lawrence Berkeley Lab 510-486-5136 NEchols(a)lbl.gov

refinement in low resolution
by r n 17 Dec '09

17 Dec '09

Hi I am trying to refine the model in low resolution and there are multimer in the asu. I did rigid body refinement after MR , molecule did not move much and R/Rfree stays 45 % and If I do the overlap between the monomers, rms is 0.06. If I do simulated annealing or any type of refinement (group_adp), Rfree is high and R goes down, but the if do the superposition of the monomer, rms is 1.5 to 1.8. So like to know what kind of refinement is can be done in very low resolution between 5 to 6 ang data? Is it any strict ncs could be possible in phenix that should not move the monomer too much? suggestions are appreciated rn

B(sol) too high
by Matthew Merski 17 Dec '09

17 Dec '09

I am in the process of solving a series of protein/ligand complex structures and ran the Polygon tool on the series. I noticed that, in general, even when all the other statistics were good, the B(sol) term was a bit too high according to Polygon. (The structures with poorer statistics also had high B(sol) values as well.) Since this is a series of multiple structures of the same protein, should this be a concern for me? And if so, what are typical causes of a high B(sol) value? Matt Merski Shoichet Group UCSF

tls matrices etc.

does phenix compute the center of reaction pretty much like refmac does? i figure the matrices/center of reaction between refmac and phenix are identical - is that true? -bryan

Rfree refmac5 issue
by anon 16 Dec '09

16 Dec '09

Hi, has anyone had any experience using phenix with refmac5? I seem to be having issues with the Rfree flag. Phenix sets aside 8.1% of the reflection for Rfree. However when i use refmac for refinement, it reports that its using 91.4% of the reflections for Rfree........? thanks

[ phenix dev 256 ] where - or should we - be looking for the polygon output .png (the one with the polygon)? its obvious in 1.5-2, so i think its dev-256 only... -bryan
