Can geometry restraints include non-ideal target values?
by Joe Krahn 07 Dec '07

07 Dec '07

I see that phenix is using the same kind of simplistic statistical restraints as CCP4. Are there plans to improve the geometry restraints once the rest of phenix is stable? The problem with simple statistical restraints as used by CCP4 is that they completely ignore correlations due to interactions of multiple restraints. This is particularly bad for puckered rings like proline and nucleic acids. Nucleic acids get around this by using a fixed sugar pucker, which results in a lot of bad geometries for non-helical nucleic acids (many of which make it in to the PDB). However, if you consider the geometries "ideal value" and "ideal value esd" as just another way to write a harmonic restraint, then it is possible to make an improved restraint library. In this case, some individual geometry restraints will have target values that restrain towards non-ideal values in order to produce the correct result when all terms are combined. The problem is that these terms will give higher RMSD values, which would probably confuse software like REFMAC, which is designed to tweak restraint weights based on RMSDs. So, does phenix have any built-in restraint adjustments that is based on current rmsds? If so, is there a way to disable it? Joe Krahn

Hydrogens of ligands generated in elbow explode in coot realspace refinement
by Schubert, Carsten [PRDUS] 06 Dec '07

06 Dec '07

Hi, when I refine a ligand with hydrogens in coot using realspace refinement, the hydrogens explode into the surrounding density. This only happens with ligand/cif files generated in elbow and not libcheck. Coot apparently needs and additional loop in the .cif file: _chem_comp_tree.xxxx, which is missing from the elbow output. Unfortunately the geometry generated by libcheck is pretty dismal, so I can probably get around this by running libcheck on the refined coords from elbow ... Nigel, is it possible to fix elbow for the next rc? PS I am running the latest phenix (rc6) and coot 0.33 if that helps. Cheers Carsten

Question about adding hydrogrens with reduce -- parameters for phenix.refine
by Schubert, Carsten [PRDUS] 06 Dec '07

06 Dec '07

Hi I am trying to generate a model with all hydrogens placed using reduce. To my surprise it only applies hydrogens to a selected few residues. How do I coax reduce to add ALL hydrogens to my model, according to the Richardson Lab paper this should be possible? The help from reduce was not helpful in that regard. Or is adding all hydrogens a bad idea? Along those lines. If I would use another tool to generate the hydrogens, like CNS(X) or Maeastro, how compatible are the parameter files? Thanks for any input Carsten

Hi, I am using the autobuild wizard in the latest phenix release to rebuild a model from a MR solution. Since the MR-template I used has been modified with chainsaw, its sequence identity to the target sequence is fairly high.

hydrogens in low resolution structure refinement
by Stefanie Krieg 16 Nov '07

16 Nov '07

Dear all! I am refining two structures at 3.0 and 2.7 A. In some older threads on this board I found that you recommended adding hydrogens to the pdb file even at this resolution. I tried that (adding hydrogens with reduce and refine with riding hydrogens) but inspite of what I read in your postings, my R-Factors went up by 1% (not down as was predicted). Are there any other keywords which could be changed or do you have any other ideas why this could be? Thanks in advance! Stefanie

Collaborative Crystallography Program - Advanced Light Source
by Paul Adams 09 Nov '07

09 Nov '07

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://alsusweb.lbl.gov/4DCGI/WEB_GetForm/PXProposalEntry.shtml/ Initialize. 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 January/February, 2008, proposals must be submitted by November 15, 2007. -- Paul Adams Deputy Division Director, Physical Biosciences Division, Lawrence Berkeley Lab Adjunct Professor, Department of Bioengineering, U.C.

Re: [phenixbb] phenix.autobuild opinion on sequence file
by Tom Terwilliger 08 Nov '07

Hi Bryan, I haven't tried your approach, but my guess would be that the correct sequence file will be the better way to go... The side chains are fitted after building main-chain so the sequence is not going to affect the main-chain build in any direct way (though the sequence will help the wizard in identifying and correcting places where loops are built with the wrong number of residues). -Tom T At 01:32 PM 11/8/2007, you wrote: >i was thinking about giving phenix.autobuild a poly-Ser/Gly,Ala-intact (or >other incomplete variant) _sequence_file_, so it doesn't inter alia put >arginine into strands... though the solvent content will be imprecise.. > >has anyone noticed if such a trick was more/less favorable to the (proper) >complete sequence approach? any pertinent detail or criticisms >appreciated. > >-bryan >_______________________________________________ >phenixbb mailing list >phenixbb(a)phenix-online.org >http://www.phenix-online.org/mailman/listinfo/phenixbb Thomas C.

Advice about phasing procedure and phase extension in AutoSol-AutoBuild
by Schubert, Carsten [PRDUS] 08 Nov '07

08 Nov '07

Hi, I am trying to bootstrap my way into a couple of weak derivatives using a combination of Solve and the AutoSol and AutoBuild wizards. I have probably one or two fairly weak diffracting derivatives (~3A) with low FOMs (~0.3) from Solve, the native extend to ~2.A. I have a couple of questions about how to best proceed with the phasing procedure using either the wizards or a Solve/Resolve combination. 1. can I input known HA-positions into the AutoSol wizard to help Hyss find other positions? Does Hyss actually eliminate bogus sites? Solve seems to refine bogus sites to occupancies ~0.1-0.5 but with a B-factor of one, but does not toss them. How does Hyss handle this situation? 2. What is the best way to handle phase extension in the Wizards, how would one go about this? I would like to fine-tune the resolution steps myself as not to jump to far out to higher resolution. 3. What quality indicators should I look at? A couple of FOMs in the resolve runs were in the region of 0.7, but the maps were not interpretable and resolve failed to build anything. Anything else I should look at? Thanks Carsten

Yes, it is merging in each reflection, if I understand the question. Yes, you might do it with phases from a native+derivative and a hi-res native.

i have phenix 2007_08_18_1856, (and i think latest cci apps). i have a jumble of questions, i'll try step by step: [1 A] in phenix.autobuild, e.g. a SAD dataset, does the flag 'hires_file=w1.sca' (help says "Merge in hires data"), mean that phases will be extended to a high resolution limit as found in w1.sca? (vide infra) [1 B] can the labels be the same as the 'other' data (the documentation suggests this)? i have tried a few things like : phenix.autobuild data=resolve.mtz hires_file=high_resolution.mtz input_hires_labels='FPnat SIGFPnat' seq_file=seq.txt ... and i see Cell: [99.810997009277344, 99.810997009277344, 140.37300109863281, 90.0, 90.0, 90.0] New resolution: 2.20520367253 High-res file input labels: ['FPnat', 'SIGFPnat'] ... which is good, but the job promptly fails with this cryptic (to me) error message: ************************************************************ Failed to carry out AutoBuild_datafile_info_inputs: 'all_input_hires_labels' ************************************************************ ...

PDB deposition of tls refined structure
by Rene Jorgensen 01 Nov '07

01 Nov '07

Dear phenix users, I am about to deposit a 2.5A structure at the PDB. The structure has been refined using phenix.refine with strategy=tls+individual_sites +individual_adp, which actually works very well but (because of the tls refinement) also results in the output of ANISOU records for the atoms in the PDB file. When using PDB_extract during the PDB submission process the ANISOU record is picked up as regular anisotropic refinement although the resolution is too low for that. Should I just accept it and leave it as it is or should I correct the info in the Auto Dep Input Tool (ADIT) to isotropic with just the regular b-factor values? Thanks in advance, Rene Jorgensen

Re: [phenixbb] lower limits on grid spacing/binning

Probably, the original poster already got more than he bargained for, but for the records, a few more comments: > All FFT based structure factor programs require that the sampling > rates along each axis be even. I don't think this is true, unless I'm misunderstanding what "sampling rate" means. The FFT in phenix is based on FFTPACK (written in the 80s) which works for any number of grid points. FFTw also supports arbitrary gridding. > They may have other required factors > depending on the space group, but they will be happy to inform you > if you make a choice it doesn't like. They are also more efficient > when the prime factors of the sampling rates are small numbers. Try > to stick with multiples of 2,3, and 5 if possible. That's good advice. FFTPACK is fastest for transform sizes that are multiples of 2,3,4 and 5. The map calculation algorithms in phenix automatically take this into account. > All FFT programs will fail if you > sample your map courser than twice that frequency, as SFALL did for > you. This may be true for SFALL, but not for the FFT algorithms in the phenix libraries ($PHENIX/cctbx/include/cctbx/maptbx/structure_factors.h). The critical reference is: David A. Langs (2002), J. Appl. Cryst. 35, 505. As short as it is, this was an incredibly important paper. In retrospect, it is amazing that it took so long for someone to discover the trick. Ralf

lower limits on grid spacing/binning
by Terry Lang 30 Oct '07

30 Oct '07

Hey Everyone, I have been told by several crystallographers that the general rule of thumb for grid spacing when generating a map is one third the resolution (eg If your crystal structure has a resolution of 1.2 A, your grid spacing should be 0.4). Is there a mathematical reason why this ratio should be maintained or is this simply a holdover from slower computers with lower memory? More importantly for my application, is there a lower limit on how fine the grid spacing can be? In other words, is there a lower limit at which one is oversampling the data for a particular resolution? Any information and/or references would be greatly appreciated. Sincerely, Terry -- P. Therese Lang Post Doc Alber Lab, UC Berkeley

linking residues question
by Crystal K. Chuang 26 Oct '07

26 Oct '07

Hello all, I was wondering if there is a tool in RESOLVE that, when used through PHENIX, links up individual chains of residues and ties in symmetry related fragments so that, as a result, packs everything together to generate more of a globular unit? Many thanks, -Crystal

NCS interpretation
by Claudia Scotti 25 Oct '07

25 Oct '07

Dear list, I'm trying to undestand the NCS symmetry in a unit cell with 8 molecules (2 A resolution). The unit cell is almost orthorhombic (68.900 79.240 90.040 89.97 90.04 89.97), but only P1 + twinning worked for MR and for refining the structure (Rfree=0.22; Rcryst=0.18). The crystal simulated a P222 space group (the best seemed to be P21212), so I'd expect NCS axis parallel to . Now I've used phenix.simple_ncs_from_pdb to get the symmtery operators (see ouput below). I've read the manual, but I'm nevertheless finding it difficult to " see" the NCS axis. Any suggestions, please, on how to interpret the output, please, and "draw" the axis or on any alternatives on how to proceed? Many many thanks and a huge apology for the naive question (this is only my third strutcure...).

Re: [phenixbb] NCS interpretation
by Thomas C. Terwilliger 24 Oct '07

Hi Claudia, It looks to me like your ncs is almost exactly 222 symmetry, plus a centering. You can tell it is 222 symmetry because all the operators are zeroes except along the diagonal, and the diagonal elements are all 1 or -1 (or close to it). That means that the 4 unique operators go like: x y z -x -y z -x y -z x -y -z The 8 operators appear to be 2 sets of 4, with a centering operation... I made a little PDB file (at the end of this message) that shows the symmetry in these operators. If you run phenix.simple_ncs_from_pdb on it you should get back something similar to your operators. If you run the phenix.autobuild wizard one cycle of rebuilding (not rebuild_in_place) then it will try to find the most compact arrangement of your molecules, and it will also try to find the point group(s) of the molecule... in this case I think it will fail to find the point group though (as it failed with my test model made from your operators). Question: do your molecules pack nicely with this arrangement? -Tom T CRYST1 68.900 79.240 90.040 89.97 90.04 89.97 P 1 1 ORIGX1 1.000000 0.000000 0.000000 0.00000 ORIGX2 0.000000 1.000000 0.000000

Hi, I was wondering if anybody has looked into integrating phenix with KNIME (http://www.knime.org/), as part of a pipeline for structure solution. Is this something the developers have looked into? Cheers, Carsten

problems with map quality, refinement and R/Rfree
by Joe Smith 19 Oct '07

19 Oct '07

Hi all, We have data sets for a protein-RNA complex at 3.2 A resolution. . The data belong to the space group I4122 and contains one molecule of Protein-RNA complex (300AA and 16nt; 66% solvent content) in the asym unit. We have managed to get phases using Se-SAD and the present model contains 60% of the protein atoms (250 residues many of them build as Ala) and almost complete RNA (16nt). We could not locate ~20 % of the residues (present in various loops as well as at N- and C-terminal ends). First 120 residues present at N-terminal end seem to have poor relatively main-chain density and almost no side chain density. RNA and 130 residues present at the C-terminal end have good electron density for main-chain as well as side chain. The solution seems to be correct as molecular replacement trials with this model gave same solution in Phaser, Molrep and AMoRe. Solution seems to be also correct because as expected one RNA strand present in asym unit pairs with another one coming from symmetry related molecule. We have checked data in space group I4122 with CCP4 (SFCHECK, cumulative intensity distribution), Yeates server as well as Phenix.xtriage. In all the cases it indicates no twinning. However if I process the data in lower symmetry space group it does indicate presence of almost perfect twin. We realize that this could be just because of processing data in lower symmetry space group and data in all probability may still be fine. The problem is now with refinement and model building. Refinement with CNS and Refamc gave considerably higher value of R and R free. In CNS1.1, refinement with small changes in the model some time leads to large shift in R and R-free value. Refmac: R=36; Rfree=47 CNS1.1: R=40-59; R-free=45-63 However in both the cases map looks more or less same (with reasonably good density for the main-chain as well as RNA) I tried refining with phenix.refine and there is some improvement in the R(34%) and Rfree(40%) values. I think may be robust bulk solvent correction incorporated in phenix.refine has helped in this case. However, I still see no improvement in the map quality for the first 120 residues. In the absence of any clear density I am unable to build any further. I feel N-terminal domain is bit flexible and may have overall poor density. I have used Se position as well as predicted secondary structure in assigning the amino acid in the map but due to few breaks in the N-terminal domain as well as poor density I am unable to assign any amino acid into the poly ala main chain. Frankly speaking, I do not know how to proceed further. I welcome any kind of suggestions which could help us in this case. Regards Joe

What am I missing here? Any suggestions would be greatly appreciated. Thanks, Troy

"Aromatic" question
by Claudia Scotti 10 Oct '07

10 Oct '07

Dear list, I've refined a protein at 2.0 A resolution with its ligand, a small molecule which includes a phenyl group. For this, I used elbow to generate the cif file, and in this file the atoms of the phenyl ring are correctly defined as "aromatic". However, the pdb output of the refinement shows a boat configuration for the 6 carbon atoms ring, with a very nice fit to the electron density. This would suggest a flexible cyclohexyl- substituent instead of the expected, typically planar phenyl ring. As my chemistry is poor, I'd really need some suggestions on where I'm wrong: did I give the wrong cif file or does phenix recognise a better fitting in a boat structure, indicating that my ligand phenyl moiety has been reduced somehow to a cyclohexyl one? Or is the aromatic ring of the phenyl group not so planar as I've supposed it to be until now? Any help would be very appreciated.

Confused with ANAISOU in PDB
by Partha Chakrabarti 09 Oct '07

09 Oct '07

Hi, I am bit confused with two things. First I did specify individual isotopic, as following, still see ANAISOU in PDB. Is it from TLS strategy? I have used TLS in refmac, don't see it there. Second thing is, I want to tighten the water picking. How can I do that? adp { individual { isotropic = "all" anisotropic = None } group = None one_adp_group_per_residue = True tls = "chain A" tls = "chain B" Best, Partha -- MRC National Institute for Medical Research Division of Molecular Structure The Ridgeway, NW7 1AA, UK Email: pchakra(a)nimr.mrc.ac.uk Phone: + 44 208 816 2515

I need to specify a group of residues/atoms that must exist on the same plane for refinement. I think the keyword is refinement.geometry_restraints.planarities may be the right keyword, but I'm unsure as to the syntax for defining the selection?

twin fraction
by Jianghai Zhu 06 Oct '07

06 Oct '07

Hi, I am using the phenix 1.3 beta rc3 to refine a twinned structure. In the old version, phenix.refine would report a twin fraction for each cycle of refinement. I could not find the twin fraction anymore in either the log file or the output pdb file. Where is it now? Thanks.

Hinge movement for refine?
by Partha Chakrabarti 04 Oct '07

04 Oct '07

Hiya, I have used rigid body refinement in phenix.refine as suggested: refinement.refine.sites { rigid_body = chain A rigid_body = chain B } If I have a multidomain protein like kinases, or G proteins which have flexible switches, how can I define the region within a given chain?

Question about strategy in phenix.refine
by Partha Chakrabarti 04 Oct '07

04 Oct '07

Hiya, I am wondering what is the meaning of the * in the following: strategy = *individual_sites rigid_body *individual_adp group_adp tls \ individual_occupancies group_occupancies group_anomalous none Does it mean, that this option can be used (for example for high res) but not used as default? Maybe I missed it, how can i get the cif files for ligands? Refmac generates it in several cases, can that be used?

Team Leader vacancy: PX group, SGC-Oxford
by Frank von Delft 01 Oct '07

01 Oct '07

I have a vacancy for Team Leader for Infrastructure and Methods Development in my group that is still being advertised; this is the Protein Crystallography group of the Structural Genomics Consortium, Oxford. For details, please see: http://www.sgc.ox.ac.uk/jobs/07079.html, and feel free to contact me if curious. The remit of the Structural Genomics Consortium (SGC) is to solve human proteins of medical relevance and place them in the public domain without restrictions; it is funded by a consortium of public and industrial funders, and has independently operating sites in Oxford and Toronto Universities and Karolinska Institutet (Stockholm). The Oxford site solved nearly 200 such structures in its first three years, and has now entered Phase II, with 4 years of funding till June 2011; it now has an increased emphasis on chemical biology and membrane proteins. The Protein Crystallography group collaborates tightly with the 5 other groups to get their purified proteins crystallized and solved -- five per month, to be precise. Equally importantly, with all the robotics and toys you'd care for, and access not only to lots of real-life samples but also to 3 years' worth of structured data accumulated during Phase I, we're ideally positioned for development and testing of crystallographic methods, which will be the major scientific thrust of the group in this phase. Enthusiastic crystallographers, especially those that really enjoy the nuts and bolts of the technique and mucking around with tricks and toys, both crystallization and algorithms, are encouraged to apply.

Request for C shell script file for phenix.refine
by Partha Chakrabarti 01 Oct '07

01 Oct '07

Hi, I am wondering if one can have master scripts (C shell) for the macro cycle of phenix.refine that can be used from the command line. It is easier to comment out an option than having to type the whole thing.. has anybody tried it? Similar scripts exist for solve/resolve and phaser.. I should not say it, I am myself not adverse to using the GUI, it is just easier when the poor postdoc sits with the boss.. typically I face the question: where is the script file & where is the log file :)) Cheers, Partha -- MRC National Institute for Medical Research Division of Molecular Structure The Ridgeway, NW7 1AA, UK Email: pchakra(a)nimr.mrc.ac.uk Phone: + 44 208 816 2515

Dear Phenixbb, My recent installation of Phenix completed successfully, but the font in the Phenix graphics window is replaced by little rectangles. So, I cannot read any of the menus.

Re: [phenixbb] phaser with certain spacegroups
by Tom Terwilliger 28 Sep '07

28 Sep '07

Hi Joe, Yes, you can run phaser with a selected subset of the possible spacegroups in the GUI. Here is how: 1. Start the AutoMR wizard as usual, and on the 2nd screen... A. say Yes to "Search all (selected) space groups with same point group" B. Under 'Choose variable to set' , select "all_plausible_sg_list" 2. Then hit CONTINUE and you will get a list of space groups. Edit out the ones you do not want with "Parameter group options" button. You're done. When you hit CONTINUE again the wizard will carry on with just the selected space groups. 3. If you want to make sure everything is ok, before you hit CONTINUE in step 2 after selecting the space groups you like, you can also select "Search Criteria" in NAVIGATE and then the 2nd screen will come up again with just the space groups you chose.

Bulk solvent scaling problems
by seglynn 25 Sep '07

25 Sep '07

Dear all, I am using phenix.refine for the first time to refine a 4.5A structure solved by MR with individual sites (stretching things a bit, I know) and a grouped ADP per domain. Below are the R-factor per cycle stats: REMARK ------------------------------------------------------------------------ REMARK R-factors, x-ray target values and norm of gradient of x-ray target REMARK stage r-work r-free xray_target_w xray_target_t REMARK 0 : 0.6464 0.6186 7.101344e+00 7.091899e+00 REMARK 1_bss: 0.3955 0.4006 6.825652e+00 6.806242e+00 REMARK 1_xyz: 0.3200 0.3622 6.675328e+00 6.720706e+00 REMARK 1_adp: 0.3201 0.3622 6.674498e+00 6.719426e+00 REMARK 2_bss: 0.3539 0.3804 6.736883e+00 6.752128e+00 REMARK 2_xyz: 0.3067 0.3427 6.639056e+00 6.687071e+00 REMARK 2_adp: 0.3062 0.3423 6.638917e+00 6.687168e+00 REMARK 3_bss: 0.3357 0.3685 6.706475e+00 6.735398e+00 REMARK 3_xyz: 0.3082 0.3469 6.652536e+00 6.702364e+00 REMARK 3_adp: 0.3076 0.3468 6.652984e+00 6.703972e+00 REMARK 3_bss: 0.3286 0.3659 6.701854e+00 6.743421e+00 REMARK ------------------------------------------------------------------------ You can see that after the intial scaling, each cycle of bulk solvent scaling and anisotropy correction leads to an increase in R-factors of ~2%. Has anyone seen this behaviour before and maybe suggest a solution? Alternatively, is there a way I can turn off the final cycle of bulk solvent scaling before outputting the pdb and maps? Thanks in advance, Steve Glynn

Oxygen atoms in phenix.refine
by Daniele de Sanctis 25 Sep '07

25 Sep '07

Dear all, i'm experiencing a weird problem with phenix.refine. After a phenix.refine run with a pdb file that doesn't contain the atoms N, CA, C, and O all together (with sidechains atoms between C and O) the O atoms are displaced from their position. Is this a know problem? Is there anyone that have suggestions how to re-edit the pdb file accordingly instead of doing cut-past for too many atoms? thanks daniele -- Daniele de Sanctis, PhD Homo sum humani nil alienum a me puto ______________________________________________________________ phone ++ 351 21 4469 662 fax ++ 351 21 4433 664 e-mail de.sanctisd(a)gmail.com, sanctis(a)itqb.unl.pt Mailing address: ITQB, Av.

phenix and ncs
by Jan Abendroth 23 Sep '07

23 Sep '07

Hi all, I could not quite find an answer in the on-line documentation: - How does phenix.refine use ncs restraints? Does it use xyz or torsion angle restraints? - Can one define the tightness of the ncs restraints? - Can one put different restraints on mainchain and sidechain atoms?
