phenix 1.3-rc4 vs. phenix 1.3-final
by Jianghai Zhu 19 Sep '08

19 Sep '08

Hi, I have done a couple of refinements using either phenix.refine 1.3-rc4 or phenix.refine 1.3-final. And phenix.refine 1.3-rc4 always gave me a lower Rfree, about 1% lower than phenix.refine 1.3-final, which actually is pretty big. What has changed between this two versions? -- Jianghai

phenix autobuild question
by Alex Berndt 16 Sep '08

16 Sep '08

Dear phenix community, I started an AutoBuild run using the phenix GUI (ver 1.3 rc4) on a linux cluster. It worked okay and all the refinement looked pretty decent. However, after quite a while I obtained the following error message (see below). Would anyone please tell me what to do to prevent this error and get phenix get its job finished? Also, I don't understand why phenix AutoBuild creates 5 (or whatever number) AutoBuild_run_x in the AutoBuild-run_1/TEMP0 directory and not two dirs up in the tree. In other words in my /someplace/home/someuser/ work/someproject/phenix2/AutoBuild_run_1_/TEMP0 directory are more AutoBuild_run_x_ directories (with x=1 to 5). It is a bit confusing to me. A final question: I realised that the phenix.refine drastically increases the number of outliers. I know that thare is a weighting term someplace ... but what was it again? Many thanks in advance, Alex warnings Failed to carry out AutoBuild_multiple_models: Sorry, subprocess failed...message is: ******************************************************************************** phenix.autobuild \ write_run_directory_to_file=/someplace/home/someuser/work/someproject/ phenix2/AutoBuild_run_1_/TEMP0/INFO_FILE_1 Reading effective parameters from /someplace/home/someuser/work/ someproject/phenix2/AutoBuild_run_1_/TEMP0/PARAMS_1.eff Sending output to AutoBuild_run_1_/AutoBuild_run_1_1.log ******************************************************************************** Failed to carry out AutoBuild_build_cycle: failure ******************************************************************************** ******************************************************************************** work_pdb_file "AutoBuild_run_1_/edited_pdb.pdb" working_directory "/someplace/home/someuser/work/someproject/phenix2" worst_percent_res_rebuild 2.0 --------------------------------------------------- Alex Berndt MRC-Laboratory of Molecular Biology Hills Road Cambridge, CB2 0QH U.K. phone: +44 (0)1223 402113 ---------------------------------------------------

link in a double conformation residue
by mvliberato＠ursa.ifsc.usp.br 12 Sep '08

Dear all, I'm refining a protein structure with a cysteine covalently bonded with a fatty acid. However, this cysteine has a double conformation. I try to make a link with "cif_link.params", but I don't know how to describe the double conformation. How can I make this link between the fatty acid oxigen and the sulfur of the cysteine in one of the conformations? Any help would be much appreciated!

Odd twinning issue (or maybe all twinning issues are odd by default)
by Francis E Reyes 12 Sep '08

12 Sep '08

All I had a structure that seemed perfectly twinned in P41 21 2, completely built to the observable density (no peaks in 2Fo-Fc map over 2sigma) and refined to 33/35 (R/Rfree). I indexed, scaled, and merged the original unmerged data to P41, molecular replaced using the above model. Three rounds of rigid body refinement of the MR solution with group adp's dropped R/Rfree to 28/30 (while generating new free R flags based on the P41 data). The resolution was to 2.5 so I skipped the NCS. Now I try to do a second round of refinement with this time individual_sites and individual_adps with no change to the input model. The final R/Rfree's are now in the 50's? Am I missing something (fundamental) ?

difficulties with autoMR
by Feldman III, George Franklin 10 Sep '08

10 Sep '08

I am trying to run phenix.automr on what I believe is perhaps a perfectly twinned data set, at 3A resolution. It is in space group 146 and according to the matthews has 3 molecules in the asu. This is a mutant of an orriginally published structure in which only one residue has been mutated (but crystallizes in a different space group). When I give the autoMR the following input: phenix.automr coords="MR.1.pdb" data=dtscale.ref resolution=0 component_type=protein identity="95" mass=13900 build=False copies=3 seq.dat I get an LLG of 37 and the run goes quite quickly. The speed of the run itself leads me to believe that I have a correct solution regardless of the slightly low LLG, but when I open the .pdb output file there is only one molecule in the asu. Am I doing something incorrectly? Why is there only one molecule instead of 3 in the asu, and how can I go about getting the other two to appear? I did let the program go ahead run autobuild, this resulted in a structure with an r_work:.5448 and r_free:.6005. I am relatively new to crystallography, but these values seem rather high to be a good starting point for refinement. I would appreciate any advice that might help me move on with my structure. Attached is the log file from phenix.xtriage in case it may be of any help. Thank you, in advance, for all of your help and advice. Best Regards, George F. Feldman

Re: [phenixbb] Real Space R value
by Thomas C. Terwilliger 03 Sep '08

03 Sep '08

Hi Matthew, You can also use phenix.get_cc_mtz_pdb with a ligand...it should treat the ligand as a single residue. Mark also asked offline about alternate conformations...here is my answer to that: If there is only on N for each residue, it will average over all atoms in all conformations. If there are multiple N atoms, and all atoms for each conformer are grouped, it will write out the residue twice. If there are multiple N atoms and they are interspersed, it will give an incorrect answer (it will write out the residue twice but the cc values will not be for the two conformers).

PX beamtime application deadline Sept 1st!
by Peter Zwart 30 Aug '08

30 Aug '08

Dear All, The deadline for general user proposals for PX beamtime at the ALS is comming up soon! At the BCSB, we have 5 beamlines for which you can apply for beamtime. At the Berkeley Center for Structural Biology (BCSB) we have recently completed a number of upgrades: Sector 8: Recent improvements include: * A high-accuracy microdiffractometer on BL 8.2.1, allowing for centering and viewing of very small crystals * Robot automounters which can increase the screening throughput at the beamlines, and will allow for the implementation of remote data collection * A new large format (315mm active surface area) CCD detector on BL 8.2.1, facilitating data collection on large unit cell crystals Sector 5: Beamlines (5.0.1 and 5.0.3) now generate 1.5x10^11 photons per second at 0.97 Angstrom. This wavelength is slightly above the Se K edge making them ideal for performing Se SAD experiments. Beamline 5.0.2 (the tunable beamline) generates a peak flux of 8x10^11 photons per second, and the energy range of 5.0.2 has been extended to 17 keV, enabling the routine use of shorter wavelengths and anomalously scattering elements such as bromine. Please visit http://bcsb.lbl.gov/ for more details about the Center and its beamlines. If you'd like to apply for Oct/Nov/Dec beamtime at the Advanced Light Source, please submit a General User proposal by September 1, 2008.

User proposal submission for Collaborative Crystallography at BCSB
by Banumathi Sankaran 28 Aug '08

28 Aug '08

Dear Users, The Berkeley Center for Structural Biology (BCSB) is pleased to announce the launch of a Collaborative Crystallography Pilot Program (CC) at the Advanced Light Source in Berkeley. Through this program, scientists will be able to send protein crystals to BCSB staff researchers for data collection and analysis. The CC Pilot Program can provide an number of benefits to researchers: * Obtain high quality data and analysis through collaborating with expert beamline researchers; * Rapid turn around on projects; * Reduced travel costs. Thumbnail Description: ====================== The Collaborative Crystallography program will be piloted on beamlines 5.0.1 and 5.0.2 for one year; if successful it will be implemented on a permanent basis. CC proposals will go through the regular ALS General User proposal review process for beamtime allocation. Proposals will be reviewed and ranked by the Proposal Study Panel, and beamtime will be allocated accordingly. BCSB staff will schedule the projects to fit into the available resources. Only non-proprietary projects will be accepted. As a condition of participation, BCSB staff researchers who participate in data collection and/or analysis must be appropriately acknowledged - typically being included as authors on publications and in PDB depositions. Please consult the website for additional information at: http://bcsb.als.lbl.gov/wiki/index.php/Collaborative_Crystallography ============= How To Apply: To submit a proposal, go to: http://www-als.lbl.gov/als/quickguide/independinvest.html Click on "protein crystallography" to begin proposal. For question 3 select "Collaborative PX 501/502." For question 9, please describe a specific research project with a clear end point. In order to request CC time for October/November/December 2008 allocation period, proposals must be submitted by Sept 1, 2008. The deadline for CC proposals for the time period January/February 2009 will be November 15, 2008. Regards, Banumathi Sankaran

Refining with NCS
by Francis E Reyes 26 Aug '08

26 Aug '08

All I have 4 molecules in my ASU and I had phenix pick out my NCS operators automatically. Do a round of refinement, load 2fofc maps into coot and ask to calculate NCS Maps (Calculate -> NCS Maps). I have three new maps mapping a single chain onto the other chains (3) and an NCS average map. I look at some of the NCS maps and the question is should the model (all the chains) match to every NCS map? In my set of 3 maps, the model fits one map (independent of chain) but seems offset in the other two maps. Also if anyone has a paper/protocol for NCS refinement, I'd love to check it out (to figure out which map to fit to). Thanks!

anisotropic refinement and hydrogens in coot.
by Mark Collins 25 Aug '08

25 Aug '08

Two hopefully quick questions; 1) The phenix.refine documentation has a section 'Refinement at "higher than medium" resolution - getting anisotropic'. I have a 1.4A structure that clearly falls into this category, I've added riding hydrogens and now I'd like to try anisotropic ADPs. Is there a way, to list all residues (preferably in phenix selection format) that have "relatively small isotropic B-factors ~5-20A**2 of so."? 2) The output.pdb file from phenix.refine is I think the pdb v3.0 format. Is there an option or apps to convert to v2.3, within phenix rather using remediator (duke)? Coot still uses v2.3 files, which is fine until hydrogens are added to a pdb, because the nomenclature has changed. RSR in coot causes these 3.0 named hydrogens to fly off the residue into surrounding density. Thanks in advance, Mark

Hello Ralf, thanks a lot for Your suggestions. Yes, I have thought about that, comparing with the older version to fix the differences. Unfortunately, I was brave enough to delete my previous (precompiled) version before I realized that IRIX support has been dropped in the meantime !!! The cci_apps download area does not provide an obvious possibility to download an older version (the cci_apps packages don't have version numbers anyway). But maybe somebody could provide a link to the latest sgi-compatible version (sources and binary package, if possible)?? That would be great!

cci_apps on irix
by o.h.weiergraeber＠fz-juelich.de 24 Aug '08

24 Aug '08

Hello, I am just compiling the latest cci_apps package for the IRIX platform. I know this is unsupported, but since the package is very self-contained, I would not expect major problems with the command-line packages (who needs a gui, anyway ;)) I'm just running into two issues with the boost package which are obviously a matter of syntax: 1st: ----- Function function "boost::python::api::object_base::~object_base" is redeclared "inline" after being called. inline api::object_base::~object_base() ^ ----- 2nd: ----- Declaration is incompatible with function template "boost::basic_format<Ch, Tr, Alloc> &boost::io::detail::feed(boost::basic_format<Ch, Tr, Alloc> &, T)" (declared at line 52 of "/usr/local/archive/phenix/cci_apps-1.3/cci_apps_sources/boost/boost/ format/internals_fwd.hpp"). io::detail::feed (basic_format<Ch2, Tr2, Alloc2>&, T); ^ ----- I have attached the complete output for your reference. Maybe these problems can be corrected easily. In fact, all this may be a matter of the mipspro compilers being more strict about syntax than gcc. But how to tell the install script to use gcc??? There doesn't seem to be a standard way to provide general compilation options... Just renaming the cc binaries makes the python configure script to switch to gcc without complaints, but other packages (scons if I remember correctly) still explicitly check for mipspro ?! Any ideas how to resolve this? Oliver ------------------------------- Dr. Oliver H.

Re: [phenixbb] cci_apps on irix
by o.h.weiergraeber＠fz-juelich.de 23 Aug '08

23 Aug '08

Hello Nat, thanks for your suggestions. Yes, I have used these tricks before, but sadly, the cci_apps build system ignores them completely. As far as I can see, there is no "central" place to set these variables, and the component packages behave differently. The cleanest way to go would be to just correct the syntax problems. Until recently, cci_apps was available as a precompiled irix package (and I think it was mipspro), so maybe one of the developers could comment on the specifics of this compilation.

placing ligands in coot with phenix.elbow output
by Feldman III, George Franklin 21 Aug '08

21 Aug '08

Hi all, I am having difficulties with my ligand. My ligand is an FMN (flavin mononucleotide) and its pdb file was originally created using PRODRG. I used the DRGFIN.PDB output file to run elbow (phenix.elbow DRGFIN.PDB --opt). The output contains hydrogens, which as we all know do not work well with coot. So when I try to place my ligand in its correct position and save the coordinates in coot, I get an error of duplicated atom labels when trying to merge the molecule to the ligand using phenix.refine. I tried using the command "phenix.elbow DRGFIN.PDB --opt --write-hydrogens=False" but phenix told me that last command doesnt exist (although its posted on the web page). Manually changing the atom names will affect both the connectivity and the cif file (I think), so it is an option I would rather avoid. Is there a way around all of this? Best Regards, George (Trey) Feldman

Hi all When generating R-Free flags from phenix refine, flags are generated all the way to the limit of the data. However, shouldn't flags be generated up to the limit of the data if specified via refinement.input.xray_data.high_resolutio n ? If not, are the statistics for R/Rfree matching to high resolution data that may be suspicious ?

Hi all, A quick question about extracting info/preparing pdb file for deposition.......... I've got a pdb file after refinement using phenix 1.3b. I was wondering if there is a way to prepare this file / format this the same way as in 1.3 final where we get "REMARK IF THIS FILE IS FOR PDB DEPOSITION: REMOVE ALL FROM THIS LINE UP" and REMARK 3. i'm already running refinement 1.3 final with the same parameters just to quickly compare the resulting refined files/numbers. I guess I could do it manually but curious if there is an easier way using 1.3 final. thanks, Sid.

Resolution cutoffs. Always debated?
by Francis E Reyes 20 Aug '08

20 Aug '08

I need to put this in front of (this) crystallographic community. What are the criteria for cutting a resolution for data reduction ? Rmerge, I/sig, mean I/sig, completeness... more? I once believed that I/Sig (not averaged) greater than 2 was the cutoff, but I've read online (particularly http://www.mail-archive.com/[email protected]/msg02576.html) that this is no longer the case because of maximum likelihood. I would love to know why this is the case as well as poll the community on how they cut off their data.

Neutron exchangeable hydrogen/deuterium positions diverge
by Anna S Gardberg 14 Aug '08

14 Aug '08

Hello, PhenixBB. I am doing joint x-ray/neutron refinement of a hydrogenated protein crystal soaked in D2O buffers, and I've run into a problem with refinement. I hope you can help. I used phenix.ready_set to add deuterium atoms to the exchangeable hydrogen positions. I ran a perl script to set the initial occupancies of those to 0.5 H and 0.5 D (they had been output as 1.0). When I ran phenix.refine with riding hydrogen positions or with individual hydrogen positions, the H and D atoms refined to different positions. How can I constrain the H and D positions to be identical?

phenix pdp files and coot - FIXED
by nihmmayerm 14 Aug '08

14 Aug '08

Hi, The problem was that coot choked on the TER and BREAK lines in the PDB, once I removed these 0.4.1 reads the phenix PDBs fine. +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ I've just finished refinements with latest version of phenix (/phenix-1.3-final/build/mac-intel-osx/bin/phenix) in which I used riding hydrogens added with reduc (Molprobity) version and TLS - so I have anisou records - and a bunch of acs. When I open files in coot (coot/0.4.1/bin/coot) I see only 1 chain (I have a dimer chain A and B) and no solvent or other heteroatoms. The file displays fine in pymol - but I want to rebuild with coot. Any ideas ? I'm using the SBGrid install of coot, and a local installation of phenix. Thanks - Mark
