Twinned Refinement
by Axelrod, Herbert 20 Mar '07

20 Mar '07

Hi, I was wondering if anyone has tested the new version of phenix.refine for the refinement of twinned diffraction data. Last week at Asilomar, Pavel presented a nice talk at Asilomar on the capabilities of phenix.refine to handle twinned data. Best wishes, Herbert L. Axelrod Stanford Synchrotron Radiation Lab

phenix.refine crash
by Jianghai Zhu 19 Mar '07

19 Mar '07

Hi, I was using phenix.refine from the latest cci apps bundle to do tls +individual_sites+individual_adp refinement. The program crashed with the following error message. ----------Target weights (before refinement)---------- Traceback (most recent call last): File "/nfs/home/jzhu/cci_apps_sources/phenix/phenix/command_line/ refine.py", line 5, in <module> command_line.run(command_name="phenix.refine", args=sys.argv[1:]) File "/nfs/home/jzhu/cci_apps_sources/phenix/phenix/refinement/ command_line.py", line 75, in run call_back_after_monitor_collect=call_back_after_monitor_collect) File "/nfs/home/jzhu/cci_apps_sources/phenix/phenix/refinement/ driver.py", line 1108, in run log = log) File "/nfs/home/jzhu/cci_apps_sources/phenix/phenix/refinement/ strategies.py", line 245, in refinement_machine log = log) File "/nfs/home/jzhu/cci_apps_sources/phenix/phenix/refinement/ weight_xray_chem.py", line 222, in __init__ compute_gradients = True) File "/nfs/home/jzhu/cci_apps_sources/mmtbx/mmtbx/restraints.py", line 144, in energies_adp_aniso xray_structure = xray_structure, File "/nfs/home/jzhu/cci_apps_sources/cctbx/cctbx/adp_restraints/ __init__.py", line 109, in __init__ self.check_flags(fl_i) File "/nfs/home/jzhu/cci_apps_sources/cctbx/cctbx/adp_restraints/ __init__.py", line 177, in check_flags assert not fl.use_u_aniso() AssertionError Anyone has any idea what is happening?

More stringent water picking
by Schubert, Carsten [PRDUS] 19 Mar '07

19 Mar '07

Hi, is it possible to increase the stringency criteria for picked waters, besides increasing the sigma level? E.G. something on the order of the H-bonding criterion found in CNS? I find that the automated water-picking routine gives me quite a few waters, which are not necessarily justified by visual inspection of the maps. Thanks Carsten

Thanks Guys, would it be possible to implement the H-bonding criteria? From my experience with CNS it worked quite nicely. Right now I end up with ~350 waters in a 2.3 A structure of a 30kDa protein, which is a bit much. -----Original Message----- From: phenixbb-bounces(a)phenix-online.org [mailto:[email protected]] Sent: Monday, March 19, 2007 1:02 PM To: PHENIX user mailing list Subject: Re: [phenixbb] More stringent water picking Hi Carsten, thanks for your question! The main water picking criteria in phenix.refine are: 1) Fo-Fc map; 2) 2Fo-Fc map; 3) macromolecule - water distance; 4) water-water distance; 5) B-factors and occupancies max/min values; plus some more of expert level ... There is no specific H-bonding criteria implemented. You can play with sigma cutoff for both maps and with the distances above. In most of the cases it the reasonable behavior. I would be interested in Paul's (Adams) comments about his experience of usefulness of H-bonding criteria in CNS. Thanks! Pavel.

Re: [phenixbb] pdb waters

Hi, yes, the waters in your file do not match the Monomer Library definition. If you simply replace O1 with O that will fix the problem. For example: GOOD record: ATOM 22792 O HOH X 1 37.309 34.504 -14.174 1.00 38.28 O BAD record: ATOM 22792 O1 HOH X 1 37.309 34.504 -14.174 1.00 38.28 O > I have tried running elbow on my pdb already with no luck. using your > command I get the error message: elbow.builder: error: no such option: > --do-all That makes me thinking that you are using an old version of CCI Apps or PHENIX. Are you using the latest one? Is the command you run looks like: % elbow.builder x.pdb --do-all Nigel: do you have any comments? Pavel.

Re: [phenixbb] Few questions -- FreeR flag specification
by Tom Terwilliger 15 Mar '07

Hi John, I'm sorry for the slow reply; I was on a site visit and out of email contact. The AutoBuild wizard in the current version (which I am afraid you probably do not have!) does try to take the FreeR flags from your input file. You can also tell it specifically to do so with the GUI and in the command-line with refinement_file=ref.mtz input_refinement_labels="FP SIGFP None None None None None None FreeR" If you have version 1.25a , then you still should be able to specify the column for FreeR flags in the GUI window that asks which column labels to use (I could be wrong about that, however, as I don't have this version on my computer any longer). You should also be able to specify them with a script: phenix.runWizard AutoBuild AutoBuild.start_from_model terwill@rosie> cat $PHENIX/phenix/phenix/wizard_scripts/AutoBuild.start_from_model # AutoBuild.start_from_model # script to run a AutoBuild starting from a model # Version 1.26 of 26-Jan-2007 # run with: # phenix.runWizard AutoBuild AutoBuild.start_from_model [restart] # if you specify restart it will forget everything, # otherwise it will continue on from where it is now. input_ncs_file NONE # heavy-atom or PDB file for finding NCS input_data_file $PHENIX/examples/p9-sad/solve_1.mtz # file with experimental data. # Can be any format if only FP SIGFP; must be mtz if phases or HL or FreeR input input_labels FP SIGFP None None None None None None FreeR_flag # optional # line defining the 9 columns in input_mtz_file corresponding to # FP SIGFP PHIB FOM HLA HLB HLC HLD FreeR (use "None" for missing) input_map_file $PHENIX/examples/p9-sad/resolve_1.mtz # Optional map-coefficients file for first rebuild input_map_labels FP PHIM FOMM # optional line defining the 3 columns # in input_map_file corresponding to FP PHIB FOM ("None" for missing) input_seq_file $PHENIX/examples/p9-sad/seq.dat # file with sequence in 1-letter form # separate chains with >>> resolution 2.5 # high-resolution limit solvent_fraction 0.60 # you can put any other parameters here input_pdb_file $PHENIX/examples/p9-sad/p9.pdb # input PDB file for rebuilding rebuild_in_place True # rebuild my_model.pdb in place # (as opposed to building from scratch) start_chains_list 4 # chain 1 starts at residue 4 # rebuild residues 21-27 of chain "" and 31-42 of chain "" # rebuild_res_start_list 21 31 # rebuild_res_end_list 27 42 # rebuild_chain_list "" "" # n_cycle_rebuild_min 5 # n_cycle_rebuild_max 10 # AutoBuild will run automatically from here on with no more inputs I hope that helps!

matt, >>> Number of atoms with unknown nonbonded energy type symbols: 308 just curious, did you have 308 waters? as peter said, hard to determine exact problem without some files or examples to look at. also phenix does a good job with water picking, in my little experience. just one more question, when you do get the refinement to work, is your ligand(s) included with the protein model? just no waters, right? it wasn't completely clear from your message. if the ligands aren't included, i recommend adding it(them) back and see if refinement works. then if that works, try water picking within phenix. again, best of luck. cheers, nick -----Original Message----- From: Matthew Bowler <mwb(a)mrc-dunn.cam.ac.uk> To: noinaj(a)uky.edu, PHENIX user mailing list <phenixbb(a)phenix-online.org> Date: Thu, 15 Mar 2007 14:15:45 +0000 Subject: Re: [phenixbb] phenix.refine problems with my pdb Thanks for replies so far....

Few questions
by john kryst 15 Mar '07

15 Mar '07

Hi phenixbb !! I have few questions. 1. Is there any utility in phenix to write out pdb formatted (which is ready to deposit) output file.. like xtal_pdbsubmission utility in CNS. 2. In Autobuild wizard how to ask the program to use the Free R flags present in the file. It always generates new Free R flags during refinement. One general question. Does the rmsd estimation (for eg. rmsd_bonds ) depends on the program we use ?? I have been refining in CNS. then i used Autobuild wizard to build my model. when i went back to cns the rmsd of bond increased (0.0218 A). But phenix.refine says it it 0.007A. Thanks in advance for your kind inputs. regards john

Two groups per residue and multiple trajectories for simulated annealing
by Stephen Graham 02 Mar '07

02 Mar '07

Hi all, I am taking my first tentative steps into the world of phenix.refine with a somewhat problematic 3 A data set and I had a few questions that Google couldn't answer. I am running phenix.refine version 1.24.1b (intel-linux-2.6) from the command line. Firstly, is it possible to do 'grouped' adp refinement with 2 groups per residue (like the good old bgroup.inp of CNS)? Secondly, is it possible to specify multiple starting trajectories for simulated annealing?

questions
by Jianghai Zhu 17 Jan '07

17 Jan '07

Hi, Got some questions in using phenix.refine. 1) Can phenix.refine use the ligand library generated by refmac5? 2) How do I use elbow to generate the ligand library when I have more than one kind of ligands? When I used --residue=xxx more than once, elbow will only generated library for the last ligand. If I use elbow multiple times to generate multiple libraries, how do I read the libraries in? Should I combine them to one file? 3) When I ran phenix.refine, I found the following message in the log. Number of residues, atoms: 32, 418 Unusual residues: {'NAG': 22, 'MAN': 10} Classifications: {'undetermined': 32} Link IDs: {None: 31} Unresolved non-hydrogen bonds: 32 Unresolved non-hydrogen angles: 64 Unresolved non-hydrogen dihedrals: 22 Unresolved non-hydrogen chiralities: 32 Number of residues, atoms: 18, 28 Unusual residues: {'GOL': 2, ' MG': 2, ' CA': 14} Classifications: {'undetermined': 18} Link IDs: {None: 17} I already gave the cif library for NAG. Looks like nothing happened. How come phenix.refine doesn't recognize Glycerol, Mg, and Ca? 4) The refinement (TLS + ML + B individual) went through, I got reasonable R, Rfree, rmsdBOND, rmsdANGLE. But the B factors are pretty low. The B factor of the backbone is much lower than the side chain, some have numbers like 4. Some metal atoms also have B factors around 4. What did I do wrong? Thanks.

by Ralf W. Grosse-Kunstleve 17 Jan '07

Hi Jianghai, I think the large memory consumption is due to the large number of triplet phase relations. Using the --real_space_squaring option may help. > The MAD data only goes to 4 A. I tried SOLVE and based on the CC > table output from SOLVE, the anomalous signal goes to 4.3 A. I > believe the cut of CC in SOLVE is 0.3. Unfortunately, the native > data is not isomorphous. Finding 50 Se given only 4.3 A resolution is difficult. I'm sorry to say I'm not very hopeful, but I'd try all tools out there. I'd also play with the resolution cutoff. hyss used 4 A in your case. I'd try 4.5 and maybe even all cutoffs 4.4, 4.3, 4.2, 4.1 if you can afford the CPU time, with --real_space_squaring first, without it if nothing worked still. Another question is the space group. You cannot distinguish I222 and I212121 from the systematic absences. Are you certain it is I212121? To find a cluster, lower the resolution significantly. I've had success with 6 A cutoff (--resolution=6). The atom type doesn't really matter, Ta should be fine. If it works, hyss will give you atoms around the centers of the clusters. You have to fit the whole cluster yourself. I'm not sure about the best approach for this (inspecting the map with coot and place the cluster manually?). Maybe someone else can help? How many clusters do you expect? In general, the more you expect the more data you need. I.e. a 6 A cutoff may work for finding a couple of sites, but for say 10 sites you'd need 5 A. -- These numbers are just to convey the idea. What works exactly depends highly on the available data. Hope this helps. Cheers, Ralf

Re: [phenixbb] CCI apps bundles upgrading
by Ralf W. Grosse-Kunstleve 20 Dec '06

20 Dec '06

Hi Miguel, Thanks for asking the question! I just added this information to the CCI Apps download page: Please do NOT install CCI Apps inside an existing Phenix installation. It is best to install the CCI Apps bundle in a new, separate, empty directory. To override the Phenix commands with more recent equivalents in CCI Apps (e.g. phenix.refine), source cci_apps_build/setpaths.csh AFTER source phenix_env. Sorry for not explaining this earlier. It is just one of the things we don't usually think about as developers. Please let us know if there are other issues like this. Cheers, Ralf

Anisotropic ADP
by James Fraser 17 Dec '06

17 Dec '06

Hello, We've just started using phenix.refine and I'm a bit confused about whether anisotropic ADP's are actually being used or not. On the wiki (http://www.phenix-online.org/phenix_wiki/phenix.refine) it says: << phenix.refine is the macromolecular refinement engine of the Phenix suite. It features * Individual as well as grouped B factor refinement * Anisotropic or isotropic+anisotropic B factor refinement * TLS refinement >> However, the documentation says (http://www.phenix-online.org/download/documentation/phenix/phenix/structure…): << Current limitations * No restrained individual anisotropic ADP refinement >> In my .def file I can set: adp { individual { isotropic = None anisotropic = chain a force_all_to_be_refined_isotropically = True } and get ANISO lines in my output pdb. But I'm confused as to whether this is actually refining with individual anisotropic b's for chain a (analagous to refining with anisotropic temperature factors in refmac). Should I be resetting the force_all... to false? Can someone with more knowledge clarify this? Thanks, the program seems to be working great otherwise! James Alber Lab UC Berkeley

Re: [phenixbb] questions / TLS+NCS bug
by Pavel Afonine 15 Dec '06

15 Dec '06

Hi Jianghai, Thanks for the .log file ! I looked at it and now I think I now what's the problem: this is the bug in phenix.refine that we will fix for the next release. The bug arises when you try to refine using TLS and NCS at once. Sorry for this. The possible solution is to split your refinement into 2 parts: 1) First, refine coordinates and isotropic B-factors. Use NCS restraints. DO NOT refine TLS. 2) At the end, as the final tune up, refine ONLY isotropic B-factors + TLS and do not refine coordinates. For this run, please REMOVE all NCS information (NCS selections) from the command file. This refinement run should be the final one. Once again, sorry for the inconvenience. This will be fixed in the next release of CCI APPS and PHENIX. Once this fixed, you will be able to run everything in "one go" and in any combination. Please let me know if what I suggested helped you. Any further questions are welcome! Cheers, Pavel. Jianghai Zhu wrote: > Here is the log file.

Phenix 1.24 and Fedora Core 5_64
by Nicholas Noinaj 09 Oct '06

Hi, I have loaded PHenix 1.24 onto a system with Fedora Core 5 (ix86_64). THe computer has an AMD X2_64 4400+ processor, 2 GB RAM, 3X120GB Sata HDs, ASUS A8N-Sli Premium Mobo, and an Nvidia 7600 GT graphics card. When I install PHenix, everything seems to load okay, except it seems to take a bit longer to install than with RHEL3 did, stalling for bit on one of the modules (sorry, can't remember which one exactly). Then after a while, the installation completes without any errors and I setup the environment as instructed for /bin/bash. I then type [phenix] to start the program, but again nothing happens for a very long time (30 minutes or more), and then the Phenix interface finally loads. But then, everything is very sluggish and takes a very long time to load or even stops responding (setup/parameter windows in particular). I have installed Phenix 1.24 on RHEL3 and not experienced any of these problems, so I am a bit clueless. FUrther, I am a Linux 'newbie' and this was my first time installing Fedora Core 5 (64), so it is possible that i haven't installed everything that Phenix needs, yet I did not experience any problems at all with the FC5 installation, ran smoothly. If you have any suggestions or insights as to what my problem or mistake may be, I thank you in advance for your feedback and assistance. I am eager to get Phenix purring away on my latest PC. Cheers, Nick the environment as instructed for /bin/bash.

Solvent in Auto_Build
by Jeff Bush 10 Sep '06

10 Sep '06

Dear Dr. Adams, and/or other Phenix experts, I have done water-picking in CNS and some refinement in Refmac-5 in ccp4 and subsequent manual adjustments of waters in Coot and O. I have discovered that CNS seems to like the format 'OH2 TIP' for listing waters, whereas refmac only likes HOH. When I then run Auto_Build in the Phenix GUI, I get the following error message: Input failed Sorry, the PDB file /path/filename.pdb has an incomplete residue (or conformer/residue combination) in conformer ' ' chain S residue HOH 733 because the conformer is missing the following main chain atoms: [ 'N', 'CA', 'C' ]. The first water in my pdb file is indeed the one in question above. Apparently Phenix is thinking that this water should be a protein residue instead of solvent. Can anyone help me with this and tell me what I need to edit in the pdb file so that Phenix recognizes it as solvent instead of protein, or do I need to delete all waters and repick them in Phenix. I have tried changing the segid to from A to S with no success. Many Thanks, Jeff B.

Re: [phenixbb] Phenix 1.24.1 update/reinstall
by Petrus H Zwart 02 Sep '06

No way to update, just reinstall from scratch. Remove the sourcing of the phenix_env file from the .cshrc file (or so) and replace iot with what the phenix installer tells you. You can leave the old phenix sources sitting on your disc for senstimental reasons, or just remove it. A small tip, source your phenix distribution after you source ccp4. This will ensure that the most upto date version of various cctbx command line utilities will be used (otherwise you might have to call mmtbx.xtriage_1.24.1b instead of mmtbx.xtriage) HTH Peter Hi, i have Phenix 1.1 installed on a Linux workstation and would like to update it to Phenix 1.24.1. Is there a way to just update the old version or do I need to uninstall Phenix 1.1 and then install Phenix 1.24.1? If I need to uninstall Phenix 1.1, what is the best approach to accomplish this (sorry, Linux newbie)? Thanks in advance for all your feedback!

In the version you have, unfortunately the AutoSol keywords res_phase and resolution do almost the same thing, so you cannot do what you are asking for. This is fixed for the next version. An update patch will be available shortly to do it as well. I'm sorry for the problem! -Tom T Thomas C.

phase extension through phenix
by Pramod Kumar JRF 11 Aug '06

11 Aug '06

Hi all I have one more question. Is any way in phenix GUI through which i can do phasing to lowere resolution, further phase extension to higher resolution? Becouse, my SAD data with single SeMet in whole protein of 3.5 Ang which have somewhat better phases and FOM at 5.0 ang resolution than 3.5 Ang resolution. Is it possible through phenix? If anybody have any one can help me? Thanks in advance. Pramod Kumar, c/o Dr. Shekhar C.

a few questions
by Jianghai Zhu 06 Aug '06

06 Aug '06

Hi all, I have a structure refined to 2.5 A. After simulated annealing (start temp = 5000, cool rate = 25, final temp = 100, include TLS refinement and NCS restraint), my R and Rfree are 24.6% and 28.7% respectively. I then turned off the SA in the generated def file and carried on the combined refinement. My R and Rfree went up to 25% and 29.2% respectively. Why did the Rfree go up after refinement? In the remarks of the output pdb file, I have one line, "REMARK twinned : True". What does this mean? The RMSD of bonds and angles after either SA or combined refinement are about 0.006 and 0.851 respectively. Don't you guys think the geometry restraints are too tight? How do I change the weight in PHENIX? Thanks.
