Map Segmantation
by Yangqi Gu 22 Mar '19

22 Mar '19

Hi Everyone, I have a naive question about segmentation. I have a low resolution map of a filament (~20 A) and I know the helical symmetry. I have monomer sequence but no structure. I am wondering if I could segment the filament and obtain the monomer density? Does segment_and_split_map work on the low resolution case? Best, Yangqi -- Yangqi Gu Graduate Student Malvankar Lab Yale University, West Campus

mmCIF for deposition

Hi all, Following the instructions given here: https://www.phenix-online.org/documentation/overviews/xray-structure-deposi… I’m attempting to use mmtbx.prepare_pdb_deposition to insert sequence information into the mmCIF that contains the model coordinates.

FEM by using FoFc map
by Danilo Belviso 18 Mar '19

18 Mar '19

Dear all, I am interested in fitting a ligand in the case of a structure where water molecules have been already placed. I know that this is not the standard procedure, but these water molecules are quite sure. To do this, I used ligand fit procedure with command "lig_map_type = *fo-fc_difference_map fobs_map pre_calculated_map_coeffs" command. At the end, the procedure provides ligands with low CC (0.4-0.55). So, I would try ligand fitting by using FEM of Fo-Fc. The rationale is that FEM of Fo-Fc could help (likely) ligand fitting, by consider the presence of water molecules at the same time (Fo-Fc should be 0 where water molecules are placed). Maybe nothing will change, but I would try. I calculated FEM by using phenix.fem start_FEM.pdb start_FEM.mtz input.xray_data.label='FOFCWT' and also by using phenix.fem start_FEM.pdb start_FEM.mtz maps.map_coefficients_label='FOFCWT PHFOFCWT' file_name_prefix='FEM_map' where start_FEM.pdb and start_FEM.mtz are the pdb and mtz resulting from the refinement with water. However, by checking the the fem maps by coot, I notice that fem is completely different from Fo-Fc and it is not the expected feature-enanched Fo-Fc. Is the procedure and keywords correct to perform FEM calculation of Fo-Fc? Do you have any suggestions?

Re: [phenixbb] Fo-Fo difference map for non-isomorphous datasets

My metal ion of interest is Cesium in this case, so I guess I am more interested in using this approach for visualization rather than peak identification - the strong density of Cs is fairly obvious I have attached a few images of the superimposed (Fo, Phi) maps and resulting difference map using either Superpose maps in phenix or transform_map in coot following Tim's suggestions. I also tried using maprot (CCP4) to apply the rotation/translation operator from the LSQ superpose but the resulting map was not superposed correctly (not sure why). Both results seem kind of reasonable - I have shown one of the difference peaks for what is likely to be a bound Cs. For both approaches the peak was very obvious at a 3 sigma level, and could still be observed to around 10 sigma in both cases. I am still unsure about differences in scaling, so although strong positive peaks can be identified, I wouldn't be confident using the map to interpret smaller differences. In response to Eric - I checked the anomalous signal, which was fairly weak. The resulting anomalous difference map did show positive peaks up to a level of ~10 sigma that matched those observed in the above real-space difference maps, with a 3 sigma level corresponding to 0.0137 e/A^3. The CCanom was also low (1-5% between shells), so I was thinking that another approach might be more suitable for this data?

Dear phenix developers, I have found that QM calculations in phenix.elbow fail due to an error: *bad fp number.* I've found the source of the error in phenix-1.14-3260/modules/elbow/elbow/quantum/run_utils.py at line 11: easy_run.call('./%s.csh >& /dev/null' % project) should be : easy_run.call('./%s.csh 2>&1 /dev/null' % project) Also jaguar template (phenix-1.14-3260/modules/elbow/Jaguar.csh) is a bit outdated. For $SCHRODINGER/jaguar paramether -PROC was replaced by -PARALLEL also, it seems that programs seeks for wrong input file. So I suggest that: $SCHRODINGER/jaguar run -PROCS %d -WAIT $PROJECT should look like: $SCHRODINGER/jaguar run -PARALLEL %d -WAIT $PROJECT.in Can you please fix this issues in next releases? -- Evgenii Osipov Laboratory for Biocrystallography, Department of Pharmaceutical Sciences, KU Leuven O&N2

Are TLS parameters applied when TLS refinement is OFF?
by Mark Saper 05 Mar '19

I have a structure where at one stage TLS parameters were determined and then refined. It caused the R-free to increase so I stopped refining the TLS parameters. Are the TLS parameters still applied to the structure on subsequent refinement runs even when the TLS refinement is off? Is it appropriate to refine anisotropic B’s for a high resolution (1.35 Å) structure AND apply TLS parameters? Thanks, Mark _______________________________________________ Mark A.

Rotamer restraints in phenix.real_space_refine

Hi - Am I right in thinking that rotamer restraints behaves differently in latest official release (1.14-3260) compared to last but one official release (1.13-2998)? Issuing rotamer_restraints=True from command line or GUI used to give 0% rotamer outliers in the molprobity analysis at end of log in 1.13-2998 but now in 1.14 gives non-zero for same input model. It is as if they are not being applied. In the old log file it used to clearly print - **Update rotamer restraints*** after every macrocycle, in the 1.14 logs this is omitted. Many thanks, Ashley

Real space vs reciprocal refinement
by Maheshwaran.V 03 Feb '19

03 Feb '19

Dear phenixbb! In the current version of phenix.refine contains the separate option for refinement: xyz (reciprocal space) and xyz (real space ). What does it mean and how it differs from the previous versions which had xyz and real space instead. So I just wanted to know what does it actually do? Can we run both of them simultaneously? Is it advisable to do both refinement for DNA ? - Mahesh India.

Hi Andrew, You should use group constrained refinement to link the occupancies of each isomer. You can see the documentation for how to implement it. https://www.phenix-online.org/documentation/reference/refinement.html#occup… Cheers, Nick From: <phenixbb-bounces(a)phenix-online.org> on behalf of Andrew Philip Thompson <andrew.thompson(a)adelaide.edu.au> Date: Wednesday, January 30, 2019 at 10:18 PM To: "phenixbb(a)phenix-online.org" <phenixbb(a)phenix-online.org> Subject: [phenixbb] Occupancy larger than 1 Hi Phenix BB, We discovered that a fragment had degraded in our crystallography condition and the product was observed bound in the resulting crystal structure. Unfortunately we have been unable to separate certain stereoisomers of this compound or its analogues, and so are looking to simultaneously model two of the isomers into the crystal structure. I have made a .cif file corresponding to each isomer and modelled them into my crystal structures with altloc tags A & B, however after refinement, the occupancy of the two adds up to more than 1 in some instances (ie. 0.51 and 0.53). I’ve never had this before when trying to model dual conformations of the stereoisomers. I tried to make the ligands the same residue number as discussed in a previous thread (http://www.phenix-online.org/pipermail/phenixbb/2011-March/016859.html), however neither coot or pymol will open the pdb file after refinement if I do this. Unfortunately I am unable to share the pdb file as we do not want to disclose the compound structure. Does anyone have any suggestions as to how to proceed?

using phenix.refine results in coot on another computer
by Christian Biertuempfel 30 Jan '19

30 Jan '19

Dear all, I often run phenix.refine on a server but I would like to use the results on my laptop for further manual building. Is it possible to somehow export the todo lists (outliers/problems) identified in phenix.refine/molprobity as a script in order to use them in coot on another computer? Alternatively, is it possible to open the results from phenix.refine in a gui with coot integration on another computer (without access to the original data partition)?

unrestrained refinement
by Kaiser, Jens T. 29 Jan '19

29 Jan '19

Hi! I'm trying to do unrestrained refinement of a small molecule in phenix. I have done this many years ago, but it seems whatever I try, phenix.refine now complains about missing nonbonded energy type for all atoms. The pdb file I supply has the following format (just one line) HETATM 33 C81 UNK 1 3.117 14.425 18.765 1.00 1.45 C I tried unchecking all references to geometry restraints in the GUI, setting wc and wu to 0 I also started from a default .eff file and set all references to restraints to either True of False (depending what they said). I also tried the line from the phenix.refine documentation: phenix.refine ../cif_in/mkt_a.ent ../data/181119/proc/137C3/XDS_17000.HKL strategy=individual_sites wc=0 refinement.input.symmetry_safety_check=warning refinement.input.xray_data.r_free_flags.generate=True I'm using phenix v 1.14-3260 from an sbgrid environment. Any pointers welcome. Cheers, Jens

Announcement: SpringerBriefs in Crystallography
by Dorothee Liebschner 28 Jan '19

28 Jan '19

Hi everyone, I would like to circulate the announcement of a new series of crystallography monographs entitled “SpringerBriefs in Crystallography” ( https://www.springer.com/series/16236). Areas of interest include structural biology. The announcement below is on behalf of the editor-in-chief, Prof. M. Nespolo. Best wishes, Dorothee Liebschner Series editor for biological crystallography, SpringerBriefs in Crystallography ========================================= Dear Colleagues, It is my pleasure to announce the launch of a new series of crystallography monographs under the title “SpringerBriefs in Crystallography”. They cover a new discipline within the “SpringerBriefs” collection, which publishes concise monographs with an intermediate scope ( https://www.springer.com/gp/authors-editors/book-authors-editors/springerbr… ). SpringerBriefs already covers 84 fields spanning a wide range from natural sciences to law, social sciences and more; crystallography is now the 85th field. The new series is published under the auspices of the International Union of Crystallography and all the manuscripts will be peer-reviewed by the series editors, as well as external reviewers when necessary. It takes an intermediate and so far uncovered place between articles published by the IUCr journals and full monographs. The IUCr publishes several types of articles in its journals (https://journals.iucr.org): • Research Papers, which are full-length manuscripts that normally do not exceed 15 journal pages (about 15 000 words); • Short Communications, for the presentation of topics of limited scope or for preliminary announcements of novel research findings; • Lead Articles, authoritative, comprehensive and forward-looking reviews of major areas of research interest (by invitation); • Feature Articles, focused surveys covering recent advances in an area of current research, which do not aim to be comprehensive, and are generally about ten journal pages (10 000 words); • Topical Reviews, which aim to capture the current trends of a field and are expected to be relatively short (about 6000 words and a maximum of 50 references, with half of those having been published in the last three years); • Letters to the Editor, which may deal with non-technical aspects of crystallography, its role, its propagation, the proper function of its Societies etc. • Scientific Commentaries, which discuss articles of particular importance for the readership of the journal. Full monographs spanning hundreds of pages are published in the IUCr/OUP monographs, and textbooks in the IUCr/OUP texts (https://www.iucr.org/publications/iucr-oup). SpringerBriefs in Crystallography aims at publishing shorter monographs, typically between 50 and 125 pages, where specific topics are dealt with more in detail with respect to what one could do in a Lead Article or Topical Review, in particular with a more pronounced accent on the background. Also, more space is given to some fundamentals which would not find place in a Lead Article or Topical Review, with the aim of providing the reader a more pedagogical introduction (whenever suitable) without the need to look for it in a separate text. Publications in this series help support the Outreach and Education Fund for the International Union of Crystallography (https://www.iucr.org/iucr/sponsorship/iucr-outreach-fund). The website of the new series is available at the address https://www.springer.com/series/16236, where you find more details as well as the responsible editor contact information, who upon request can provide you with a proposal form. On submission the responsible editor will then forward it to the series editors for discussion and approval.

ISOLDE 1.0b2 release
by Tristan Croll 24 Jan '19

24 Jan '19

Dear structural biology community, I am very happy to announce that ISOLDE 1.0b2 is now available. All the details including documentation are available on the new ISOLDE website at https://isolde.cimr.cam.ac.uk, but the following is a short list of new features and improvements since ISOLDE 1.0b1: - added support for Windows. ISOLDE is now available for all three major operating systems. - many usability and stability improvements. In particular, ISOLDE is now much more helpful when your starting model is not yet quite simulation-ready. - No more need to delete unparameterised residues from your model. You can now choose to have ISOLDE simply ignore them for simulation purposes. - Real-time smoothing of the trajectory visualisation to reduce thermal jitter. - Direct handling of real-space maps (no need to convert them to structure factors first). - Live recalculation of structure factors and crystallographic maps from F/sigF data as model coordinates change. I do hope you find it useful. Best regards, Tristan

Refining an ion on a special position
by Shane Caldwell 12 Jan '19

12 Jan '19

Hi phenixbb, I've got a question related to refinement of an ion on a special position. I have a structure with an atom placed squarely on the C2 axis. I've been able to get a mostly-reasonable model by dropping in the ion at 0.5 occupancy and turning off repulsion for the ion in question, as Pavel describes here <http://www.phenix-online.org/pipermail/phenixbb/2018-February/023689.html>. It almost completely works. The thing I find now is that during refinement there can still be some random drift of the atom away from the symmetry axis, splitting from its symmetry ghost, while I know that it should stay perfectly coincident. My resolution is 3.1 and there's no indication of a multiple conformation, so a split isn't justified. The most parsimonious model should place the ion exactly on the C2. Is there any way to enforce that either 1. x, y = 0.0 in refinement, or 2. the ion is constrained to the xyz of the symmetric version of itself. Both should get to the same place, with the metal precisely on the axis, and precisely over top of it's symmetric counterpart. Thanks!

atoms with unknown nonbonded energy type
by Danilo Belviso 11 Jan '19

11 Jan '19

Dear all, I am refining the structure of a cyclic peptide with having residues that are not in the ligand list of phenix. I would to perform unrestrained refinement by considering the very good resolution of the data. However, also in this case, phenix requires the restrain file of the ligand. I got cif file in two different way: 1) PRODRG server 2) by running phenix.elbow both produce the restrain file with no error message. However, by using such file in the refining, I get this error: Sorry: Fatal problems interpreting model file: Number of atoms with unknown nonbonded energy type symbols: 14 In the cif file, there are not atoms having 14 as energy type symbols. Could you suggest to what this message is referred to? How can I modify the cif to overcome the problem?

Re: [phenixbb] Phenix installation on Debian9.6
by Billy Poon 09 Jan '19

Hi Danilo, I have a Debian 9.6 virtual machine running and Phenix is working after en_GB is installed. The problem is with the locale. It looks like en_GB is required even though another language is used. I had to install en_GB even if I'm using en_US. When I have only it_IT.UTF-8 installed, I get the en_GB error. After installing en_GB, the GUI works normally (see attached screenshot, phenix.png). To install en_GB with instructions from https://wiki.debian.org/Locale, 1) open a Terminal and become root 2) run "dpkg-reconfigure locales" 3) Select en_GB.UTF-8 (see attached screenshot, locale.png) 4) Select "OK" and complete process. You'll have to just choose your default language, but you should have it_IT.UTF-8 as your default 5) Verify that en_GB is available with "locale -a" (Mine is shown in a terminal in phenix.png) Changing the setting for Phenix 1) Go to the <phenix installation>/build directory 2) Type "export LC_ALL=it_IT.UTF-8" 3) Run the config_modules.sh script 4) Verify that "LC_ALL=it_IT.UTF-8" is in our programs. In phenix.png, I check that <phenix installation>/build/bin/phenix has LC_ALL set to it_IT.UTF-8 5) Phenix should run and the main GUI should pop up I suspect that because Phenix is not localized, we may be requiring an English language to be installed and maybe en_GB is a default. So in phenix.png, the dates for the projects are in Italian, but everything else is in English. Also, I think our number formatting is not localized, so decimal points will be "." instead of ",". I'm sending the images to you directly since the bulletin board has some size limit and the original message with attached images is waiting approval. -- Billy K.

Dear all, I am intalling phenix on my Debian 9.6. My arch is adm64 thus I downloaded the phenix version named Kernel 2.6 (64-bit; CentOS 6). The installation procedure has been performed as suggested by the guide and no problems were obtained. However, by running phenix (after source phenix_env.sh) I get the follow output with several errors: (main.py:14196): GLib-GIO-CRITICAL **: g_loadable_icon_load: assertion 'G_IS_LOADABLE_ICON (icon)'

Do you have any suggestions to overcome such problems? I tried with Kernel 2.6 (64-bit; CentOS 5) and the 32-bit version too and the result is the same. Thanks in advance for your suggestions.

Jumping Rfree upon bulk solvent modeling
by Weinert Tobias (PSI) 08 Jan '19

08 Jan '19

Dear PHENIXBB community, i have come across a strange behavior in Phenix: * I copied Rfree-flags from a dataset with very slightly different unit cell * Refined the previously refined model against the new data * Rfactors in first round were good * Second round in refinement Rfree was up by 10 % just from the start during bulk solvent modeling and scaling * In another round Rfree was high in the beginning, and then dropped by those 10 % during bulk solvent modelling and scaling. * In yet another round Rfree started 10% lower than the previous round during bulk solvent modeling in the first cycle and then it jumps up again in the second cycle. What could be wrong? Many thanks and kind regards, Tobias Weinert

mmCIF in Phenix 1.14-3260
by Dominik Oberthuer 30 Dec '18

30 Dec '18

Dear all, I recently found that phenix.refine in version 1.14-3260 generates coordinate mmCIFs that the PDB deposition system can't handle. After struggling with this for some time I used an installation of Phenix 1.13-2998 I still have on my MacBook and used the mmCIF/PDB-conversion tool from this version and had no more trouble with uploading the mmCIF to the PDB. Maybe it is worthwhile to check which changes from 1.13 to 1.14 might have caused these issues. Thanks!

smaller the cell parameter of EM map
by dancingdream＠163.com 30 Dec '18

30 Dec '18

Dear all, The cell parameter of the EM map is always too large, which will make the model building program running very slow. But in factor, the structure is a smal part of cell. So can I smaller the cell parameter when I use phenix.map_to_structure_factors to convert the EM map to mtz file. Thank a lot! Wei
