Phenix Generate Table 1 Tool for twin-refinement statistics
by Xiao Lei 04 May '17

04 May '17

Dear All, I am using Windows Phenix Version 1.11.1. I'd like to generate table 1 for journal using Phenix "Generate Table 1 tool". In the input column, I input pdb model, data mtz, and data unmerged mtz, it gives me output statistics without twin refinement. But I'd like to show the results of twin refinement because I used Refmac5 to do twin refinement. Even I put the pdb from the output after twin refinement, the tool still gives me without twin refinement statistics. Thanks ahead for any input.

TLS refinement
by Reza Khayat 02 May '17

02 May '17

Hi, I'm having difficulty with performing TLS refinement on a highly symmetric system. The difference between the R_work and R_free increases with TLS refinement (16.5/21.4 changes to 14.4/22.2). The TLS tensors for some of the group are not sensible (if I understand the literature correctly) -there are some negative numbers for the T and L tensors (see below). The TLS groups were identified with phenix.find_tls_groups. Any suggestions would be appreciated. REMARK 3 SELECTION: chain 'A' and (resid 38 through 68 ) REMARK 3 ORIGIN FOR THE GROUP (A): 56.6459 -23.5648 -59.0695 REMARK 3 T TENSOR REMARK 3 T11: 0.2105 T22: 0.2895 REMARK 3 T33: 0.0962 T12: 0.0829 REMARK 3 T13: 0.0473 T23: 0.0007 REMARK 3 L TENSOR REMARK 3 L11: 0.0446 L22: 0.0120 REMARK 3 L33: 0.0096 L12: 0.0246 REMARK 3 L13: 0.0209 L23: 0.0106 REMARK 3 S TENSOR REMARK 3 S11: 0.0228 S12: -0.0268 S13: -0.0023 REMARK 3 S21: -0.0507 S22: 0.0526 S23: -0.0287 REMARK 3 S31: -0.0296 S32: -0.0137 S33: 0.0534? The data set is complete at 2.3Å resolution and there are no strange crystal phenotypes.

starting model using phenix.map_to_model
by Chang Sun 02 May '17

02 May '17

Hi there, I am currently using the phenix.map_to_model for model building from a cryo EM electron density map. One thing I am wondering is whether the starting model should be aligned with the original map or the shifted map produced in the process? Because in my case, most of the starting model is not retained in the final "map_to_model.pdb". BTW, Dr Terwilliger, thanks for devoloping this wonderful tool! Thanks, Chang Postdoctoral Research Associate , Gennis Lab Department of Biochemistry, University of Illinois A306 CLSL 600 S. Goodwin Ave Urbana, IL 61801 Phone: 217-333-4939

FSC curve between experimental cryo EM map and model
by #AHMED TOFAYEL# 29 Apr '17

29 Apr '17

Dear all, If I want to calculate FSC curve between experimental cryo EM map and model, what is the correct procedure to do so? I will explain what I have tried so far. Although I have variable local resolution in my map, according to FSC=0.143 criterion I have a 4 Ang map (say 1.mrc), I have used 'molmap' command in Chimera to generate a simulated map at 4 Ang. Then I used "vop resample" to take care of the pixel and box values ( then saved as 2.mrc). Thereafter, I have used "e2proc3d.py 1.mrc fsc.txt --calcfsc=2.mrc and plotted the fsc.txt file to get the curve. I am not sure if I am on the right track. My pixel size is 1.28. Best regards, Tofayel

Can I use PHENIX "Find NCS" tool to verify space group ?
by Alex Lee 23 Apr '17

23 Apr '17

Hi All, I have a protein/dna dataset (3A resolution) with space group (SG) ambiguity, it could be P32 with two copies of molecules (one copy of molecule composed of protein homodimer with asymmetric dsDNA) in asymmetric unit (ASU) or P3221 with one copy of molecule in ASU. Both SG can give me MR solutions and after Refmac P32 Rfree is around 31% while P3221 Rfree is around 34% (without any twin refine at this stage). Density maps from both SG makes sense and they are similar by eye inspection. Because of partial twinning of the dataset (estimation twin fraction alpha around 0.22) , which confuse programs of assigning the correct SG. Pointless and Xtriage suggests P6222, which we are sure it's not correct (based on performance on both MR, Refmac and biology sense that dsDNA is asymmetric, and if P6222 is true then based on Mathew coef. there will be a monomer protein with single strand ssDNA in ASU). Zanuda suggests SG P32 in both cases (input experimental data P32 or P3221 along with refined model). However, Zanuda may not work well in twin case. In short, the problem now is to choose one SG from P32 or P3221. There is one suggestion that try SG P32, as there are two copies of molecules in ASU in P32 group, try find the NCS operator in P32 and check if this operator is close to crystallographic symmetry operator or not, if it is, then SG is P3221, if it's not, then SG is P32. I did a few rounds of search in Internet, I found Phenix "Find NCS tool" and input PDB of my refined structures from both P32 and P3221. For both test, Find NCS tool did find NCS operator but in the end of the log file I see the same results as below: This NCS object does not contain point group symmetry This NCS object does not contain helical symmetry. I am asking: 1. does "This NCS object does not contain point group symmetry" from Find NCS tool mean that NCS operator in my PDB is not crystallographic symmetry operator? 2. Is there a tool in Phenix which can find the NCS operator and check if the NCS operator is close to crystallographic symmetry operator or not? Thanks ahead.

Generate a map showing local agreement between map and model
by #AHMED TOFAYEL# 18 Apr '17

18 Apr '17

Dear developers and users, Is it possible to generate a map to show local agreement between cryo-EM map and the model generated using the same map? If I am not wrong, the supplementary figure S5 had accomplished the job (using Chimera), but I don't understand how to generate a similar figure for my project. Is it possible to do with phenix? http://emboj.embopress.org/content/28/6/755 Best regards, Tofayel NTU Singapore

Dear all, I'm trying to refine the occupancy and position of two co-factors iron (III) and FEO (Fe-O-Fe) in a crystal structure. The iron (III) is placed with some occupancy on one of the iron positions in FEO. If I refine them together in Phenix with low occ phenix.refine moves the atoms apart. What is the best way of dealing with this problem? Thanks and best wishes Kornelius

What happened with Rfree between dev-2376 and now?
by Mark Saper 30 Mar '17

30 Mar '17

Hi all, I’ve been running some tests with the current dev and released versions of Phenix. If I run the same job (same input files, same parameters), the current versions consistently result in Rfree values ~1% more than Phenix version dev-2376! What changed between then and now?

help with pdbtools
by Edward A. Berry 26 Mar '17

26 Mar '17

1. I'm trying to use pdbtools and I don't quite get the syntax. How can I specify the output file name on the command line? these don't work: phenix.pdbtools 2chr_refine_001.pdb sites.shake=0.5 output file_name = shake1.pdb phenix.pdbtools 2chr_refine_001.pdb sites.shake=0.5 file_name = shake1.pdb phenix.pdbtools 2chr_refine_001.pdb sites.shake=0.5 --output file_name = shake1.pdb phenix.pdbtools 2chr_refine_001.pdb sites.shake=0.5 --file_name = shake1.pdb phenix.pdbtools --output file_name = shake1.pdb 2chr_refine_001.pdb sites.shake=0.5 phenix.pdbtools output.file_name = shake1.pdb 2chr_refine_001.pdb sites.shake=0.5 2. for the "shake" operation, is there a random seed so that it comes out differently each time? (If I do this five times with different output file names, will they all be the different?)

options in phenix.merging_statistics
by Murpholino Peligro 24 Mar '17

24 Mar '17

Hello. I was wondering what is the normal situation where one should click the boxes marked as "Keep anomalous pairs separate in merging statistics" (option1) and/or "Use internal variance of the data in the calculation of the merged sigmas" (option2)? I am asking because it looks like it is detrimental to the statistics, as you can see in the file attached (CSV file with 4 columns for no options, option1, option2 and option1&2). Thanks in advance.

difference map for cryo-EM (cryo-EM map minus model map)
by Pavel Afonine 16 Mar '17

16 Mar '17

For those practicing cryo-EM and tending to use Phenix nightly builds, as well as in response to a recent post (Re: [phenixbb] difference map based on the cryo-EM map): Next Phenix nightly build (dev-2612 and up) will have a command line tool to compute map-model real-space difference maps. One map is computed in real space: cryo-EM map minus model calculated map; it is locally scaled in some complex way to account for local variations and possibly poorly refined B-factors. In terms of reciprocal space it is an analog of: (F_obs, Phase_obs) - (F_calc, Phase_calc). The other map is computed using both spaces, and is analog of (F_obs-F_calc, Phase_obs); here no model phase is involved. I'm not sure which one of the two is better. Both maps are useful to locate ligands or yet not built pieces of the model (very much like in crystallography). Current limitations: - no GUI; - map must have origin at (0,0,0); - output file name can't be changed. To use: phenix.real_space_diff_map model.pdb map.ccp4 resolution=3.9 which will output two maps: map_model_difference_1.ccp4 and map_model_difference_2.ccp4 . If proving ligand is the purpose to compute this map, then obviously it should not be present in model.pdb. In future (once fully tested) this will be integrated into phenix.real_space_refine. The tool is 10 hours old and tested on just one model (5l4g, emd_4002.map), so bugs are not unexpected. Any feedback is welcome! All the best, Pavel

Re: [phenixbb] phenix.erraser and PHENIX_ROSETTA_PATH; problem fixed.
by Mooers, Blaine H.M. (HSC) 16 Mar '17

Hi Andy, Thank you for the clarification! Yes, I was wrong. There is still a tools subdirectory at the top level. I installed the latest version of Rosetta from source. This is version 3.8, the Feb. 25th, 2017 release. The rosetta\_options.py file is in the same location: main/source/src/apps/public/ERRASER. Following up on your suggestion, I edited the file erraser.py in /Applications/phenix-dev-2686/modules/phenix/phenix/erraser by replacing line 543 with the following: file_path = os.path.join(params.directories.rosetta_path, 'main/source/src/apps/public/ERRASER') Phenix.erraser now runs.

Open Postdoctoral Position at Oak Ridge National Laboratory
by Paul Adams 10 Mar '17

10 Mar '17

Dear Colleagues, on behalf of my colleagues I’d like to bring to your attention an open postdoctoral associate position at Oak Ridge National Laboratory (ORNL): Summary - To maximize the information obtained for diffraction experiments for structural biology, data processing methods need to be improved for marginal, weak data and also for reflection overlap. Methods will be developed that make use of knowledge about the atomic model to inform data processing methods so that reflections can be successfully deconvolved. A novel technique for full profile single crystal structure refinement will be developed. This work will be performed through a National Institutes of Health (NIH) funded consortium between ORNL and Lawrence Berkeley National Laboratory (LBNL) to develop a broad range of computational tools for macromolecular neutron crystallography. The aim of this consortium is to address the need for new computational tools and methods to deal with the increasing number of neutron macromolecular structures being determined and their increasing size and complexity. These tools will be developed in close collaboration with the PHENIX program, a NIH funded consortium between several groups. Interested candidates should visit: https://www.ornl.gov/careers Job Posting: Postdoctoral Research Associate - Computational Methods for Integrating Protein Crystallography Data / NB50615195 https://recruiting-internal.ornl.gov/sap/bc/erecruiting/posting_apply?param… -- Paul Adams Division Director, Molecular Biophysics & Integrated Bioimaging, Lawrence Berkeley Lab Division Deputy for Biosciences, Advanced Light Source, Lawrence Berkeley Lab Adjunct Professor, Department of Bioengineering, U.C.

Please attend a workshop on Measurement and Interpretation of Diffuse Scattering in X-Ray Diffraction for Macromolecular Crystallography
by Robert Sweet 08 Mar '17

08 Mar '17

Driven by recent advances in this field we will hold a workshop to discuss it. The workshop will be on Monday, May 15, 2017 at Brookhaven Nat'l Laboratory, and will be affiliated with the 2017 Users' Meeting for NSLS-II and the Center for Functional Nanomaterials. The current draft agenda is on-line here: http://usersmeeting.ps.bnl.gov/workshops/workshop.aspx?year=2017&id=136 Registration for the Workshop and Users' Meeting is here: http://usersmeeting.ps.bnl.gov/registration/?year=2017 A description of the workshop is below. The Organizers: Robert Sweet (NSLS-II, BNL), Michael Wall (LANL), Nozomi Ando (Princeton University), James S. Fraser (University of California, San Francisco), George N. Phillips, Jr. (Rice University) For answers to questions, please contact Wall: mewall(a)lanl.gov or Sweet: sweet(a)bnl.gov Description: X-ray diffraction from macromolecular crystals includes both sharply peaked Bragg reflections and diffuse intensity between the peaks. The information in Bragg scattering reflects the mean electron density in the unit cells of the crystal. The diffuse scattering arises from correlations in the variations of electron density that may occur from one unit cell to another, and therefore contains information about collective motions in proteins. A major focus of the workshop will be to provide a roadmap to the acquisition of reliable data by surveying measurement methods and discussing the increase in measurement accuracy enabled by improved detectors, experimental methods, and data integration. Missing from recent results is real information about the behavior of the molecules being studied that would guide the thinking of biochemists and biologists. To discuss these and their relative merits will be a second major focus of the workshop. The charge to this workshop will be to provide a roadmap to efforts that will provide the biological understanding we believe is hidden in the data. ========================================================================= Robert M.

Phenix.refine ignores ligand planarity restraint
by Maike Bublitz 01 Mar '17

01 Mar '17

Dear all, this has probably been discussed many times before, but I just can’t seem to find a solution for my current problem with phenix.refine: I am trying to refine a protein structure with a rather complex ligand. I’ve generated a .cif file for the ligand with eLBOW, including planarity restraints for its aromatic ring systems. However, phenix.refine keeps on distorting the 6-ring in my indole group, although all respective atoms are included in the plane definition. At a resolution of 3.0 A, I’d very much prefer to impose an ideal planar structure on this ligand. How can I convince Phenix to not distort my ligand's aromatic rings? Many thanks for your kind suggestions. Best regards, Maike ************************************************* Dr. Maike Bublitz Associate Professor of Microbial Biophysics Department of Biochemistry University of Oxford South Parks Road Oxford OX1 3QU United Kingdom phone: +44 (0)1865 613221 lab: +44 (0)1865 613318 maike.bublitz(at)bioch.ox.ac.uk<http://bioch.ox.ac.uk>

estimated coordinate error from phenix.refine
by Almudena Ponce Salvatierra 28 Feb '17

28 Feb '17

Dear all, I would like to know how the estimated coordinate error is calculated in phenix.refine, the one that is written on the pdb file as "ML based". I'm asking due to the following: For example if I am comparing two different models (structures determined at 2.1 and 2 Angstroms) but one does have a coordinate error estimate of 0.25 Angstroms and the other one of 0.6, respectively. Is the first model more reliable? The second one is reliable too but my question points towards how conservative or how more conservative should I be when describing distances , potential H bonds, coordination. Despite those different numbers in estimated coordinate error, the electron density maps look very similar or almost the same for both structures, very clear and complete at 2 Angstroms. That's why I was somehow surprised to find these difference. Thank you very much in advance Best Almudena -- Dr. Almudena Ponce-Salvatierra EMBL-European Molecular Biology Laboratory 71, avenue des Martyrs - CS 90181 F - 38042 Grenoble Cedex 9

solvent masks
by Kajander, Tommi A 10 Feb '17

10 Feb '17

Hi All, Was there a convenient way to make a solvent mask for a region with a model - its been a while - and use that to generate maps (i have a domain that is only partially visible, could not be found be molecular replacement), its there though. Could be that its not well ordered, but I was wondering if the bulk solvent masking is just wiping it out. (basicly something like half a domain, e.g. half of individual beta-strands, are missing.) resolution is bit limited (at best 3 Å) so automated building and refinement doesnt work terribly well. I could just place a model there and make a mask somewhere and include in map calculation? Thanks for suggestions, tommi

Re: [phenixbb] Running Phenix Gui on Debian 8
by Chow, Martin 08 Feb '17

08 Feb '17

I am having troubling running Phenix 1.11.1.2575 gui under Debian 8 (Jessie), and have same results with different computers that are running the same system. I have no problem with previous versions like 1.9 and 1.10. However, with 1.11, Phenix guy won’t run. It complains about Gtk+ or Glib etc and quits. I know these are related to gui tool kits. I have tried Centro5, Centro6, and even compiled it, they all give similar or same complaints. I believe command-line works, but never try. However, simple commands like —version or —-help etc work. I just tried it on Red Hat, 1.11 works without issues. Clearly, it is a problem with the Linux Distro. Thank you.

pdbtools atom_selection behavior
by wtempel 08 Feb '17

08 Feb '17

Hello all, suppose I would like to remove one alternate conformation B from residue 1 in chain A and set the occupancy of remaining atoms in that residue to 1. phenix.pdbtools alts_minim.pdb occupancies.set=1 \ occupancies.atom_selection=”chain A and resid 1” \ keep=”not (chain A and altid B and resid 1)” \ output.file_name=alts.out.pdb There are better methods to achieve that, but I eventually would like to expand this command to do other “things” to my coordinates. Well, so far I have failed to have the atom_selection to work the way *I* expect. stdout reveals that the program fails to apply a common scope to the command switches, and proceeds to reset occupancies of all atoms. Can this be done on the command line? A minimal (not) working example is attached, and your feedback appreciated. Best regards. Wolfram Tempel

Dear colleagues Hello again. I would like to scale and merge two different native datasets for a same protein complex (which semed to die off gradually in the beam) using the scale_and_merge tool. The error message was received "Multiple intensity arrays - please specify one: data_labels=I,SIGI data_labels=IPR,SIGPR" However I looked into the log file and I have actually included "data_labels = "IPR,SIGIPR,merged" . Perhaps I have missed something else in the setting? Regards Sam Sam Tang Biochemistry Programme, School of Life Sciences, CUHK
