Phenix Dock & Rebuild Python Error
by Nicholas Clark 22 Apr '25

22 Apr '25

Hi all, I'm trying to run Phenix Dock & Rebuild on a Mac (Venture 13.6.7) but I keep getting a NameError in Python that "DESKTOP_TYPE" is not defined. Does anyone have a quick way to fix this? Can I edit the code directly in that line to explicitly state that I'm on a mac or is this a variable that should be set directly in the base Python installation? Below is the entirety of the error message: NameError : global name 'DESKTOP_TYPE' is not defined Traceback (most recent call last): File "/Applications/phenix-1.20.1-4487/modules/phenix/wxGUI2/Runtime.py", line 224, in OnComplete self.handle_complete_event(event) File "/Applications/phenix-1.20.1-4487/modules/phenix/wxGUI2/Templates.py", line 491, in handle_complete_event self.add_result_panel(result) File "/Applications/phenix-1.20.1-4487/modules/phenix/wxGUI2/Templates.py", line 512, in add_result_panel params=self.params) File "/Applications/phenix-1.20.1-4487/modules/phenix/wxGUI2/Templates.py", line 980, in __init__ JobOutputPanel.__init__(self, parent) File "/Applications/phenix-1.20.1-4487/modules/phenix/wxGUI2/Windows.py", line 551, in __init__ WidgetArea.__init__(self, parent) File "/Applications/phenix-1.20.1-4487/modules/phenix/wxGUI2/Windows.py", line 512, in __init__ self.DisplayWidgets() File "/Applications/phenix-1.20.1-4487/modules/phenix/wxGUI2/Programs/DockAndRebuild.py", line 112, in DisplayWidgets if (DESKTOP_TYPE in ['mac', 'kde', 'gnome']): NameError: global name 'DESKTOP_TYPE' is not defined Thanks!

sub-unitary occupancy group restraints sum
by Kreitler, Dale 17 Apr '25

17 Apr '25

Hi, For refining an x-ray structure which has a ligand bound with multiple poses modeled as alternate confirmations, is there a way in phenix refine to maintain that the occupancy of each conformation is equal while allowing the sum total occupancy to vary (rather than equal 1)? I realize the [0,1] min/max occupancy values are adjustable parameters -- my interpretation of the docs is that this is not possible, but I thought it'd be worth asking. An example might be a ligand bound with partial occupancy near a rotational symmetry axis. Thank you, Dale ============================= Dale Kreitler AMX Beamline Scientist National Synchrotron Light Source II Building 745, Rm. 5L143 Upton, NY 11973 631-344-7318

Simulate map from model
by Ricardo Righetto 10 Apr '25

10 Apr '25

Hi, Apologies if I'm missing something obvious, but I was not able to find this in the documentation: is there a PHENIX tool for simulating Coulomb potential maps (aka "cryo-EM maps") from atomic models? I'm looking for something like the molmap <https://www.cgl.ucsf.edu/chimerax/docs/user/commands/molmap.html> command in ChimeraX, but more accurate. One such alternative is the simulate program from cisTEM, but I figured PHENIX might also have something? Thank you! -- Ricardo Diogo Righetto

Differential density peaks and hydrophobic residues
by Lucas Souza 04 Apr '25

04 Apr '25

Hi everyone, I am refining a ~3A structure using phenix 1.21.2-5419. I am at the final stages of the refinement but I am seeing some positive density on some hydrophobic residues (mainly Ile and Leu) together with a negative density around those residues (image attached). At first, I guessed that might be related to solvent mask, so I turned on optimize_mask. That did not solve the issue, although slightly decreased R values. Diffraction data was processed with autoproc+staraniso and does not seem to be twinned (normal intensity stats + map deteriorates if twinning refinement is applied). Does anyone have a guess about that?

for autobuild full sequence?
by James Holton 03 Apr '25

03 Apr '25

Hey all, Don't worry, nothing is funny today. I have a real question: Is there a way to force phenix.autobuild to build in the entire sequence? As in: the full length of the actual molecule that is in the crystal, such as what is supposed to go into SEQRES, regardless of "visible" density? I am trying to come up with a pipeline for prepping MD simulations of protein crystals. It seems proper to me that the molecule being simulated should be the actual molecular species, disordered bits an all. However, we don't seem to have good technology for building protein chains into "nothingness". Yes, I know Alphafold is a thing, but it is rubbish at clashes in the context of a crystal. I mean, I could write something, but does this tool already exist? Cheers, and happy Tuesday, -James Holton MAD Scientist

Issues with zero B-factor and ADP refinement
by sylee00＠snu.ac.kr 24 Mar '25

24 Mar '25

Dear all, I am encountering issues related to B-factors and ADP refinement in Phenix and would appreciate any insights or suggestions. I am currently working on my first PDB file, but I've noticed that many atoms in the PDB file have a B-factor of 0. As far as I understand, B-factor values are calculated by ADP refinement in Phenix real-space refinement, but even after running real-space refinement (with ADP on in refinement settings), the B-factor remains 0 for many atoms. I am currently using Phenix 1.20 on Windows (Newest version available on window). I also attempted to run Phenix 1.21 on a Linux in other computer, but when ADP refinement is enabled, the process starts normally but halts during the ADP refinement step. So I couldn't test whether the issue is fixed in the newest version. Aside from the B-factor issue, I am also experiencing an inssue related to ADP refinement: When I run real-space refinement with ADP refinement enabled, the process starts normally but halts during the ADP refinement step. According to the log file, other refinement steps proceed without issues, but it fails to progress at the ADP refinement stage. Additionally, when I try to pause the process, I receive a "NoSuchProcess" error, so ADP refinement process may have unexpectedly terminated. At first, I thought it's the issue related to system performance or hardware differences, because adp refinement with this pdb file and identical parameters works on some computer but fails on others (the same version of Phenix). Still it's weird because this issue has occurred unexpectedly, as ADP refinement previously worked in my computer under the same conditions without any problems and also other PDB files run without any problems in my computer. I would appreciate any insights or suggestions on how to resolve this. Thanks

CSD changes conformation to planar during phenix.refine
by Andrea Smith 20 Mar '25

20 Mar '25

Hi all, I have a structure where I clearly see that one of the cysteines is oxidised. I have modelled CSD instead of CYS and when I do real space refine in Coot, the CSD sits nicely in the density. When I submit the phenix.refine job, I can see that the geometry changes and now the SOOH is planar. I tried to add the CSD.cif from PDB into phenix.refine as restraints, but it doesn't help and during the automatic refinement the geometry is changed to planar again. Anyone experienced same thing? What do I do? Thank you, Andrea

Trouble with GTP/GDP refinement.
by DIEGO ORTIZ DE ELGUEA LOPEZ DE DICASTILLO 18 Mar '25

18 Mar '25

Dear phenixbb: I'm working with a GTP binding protein and have had some problems running phenix_refine. In my unit cell there are two molecules one with GDP and one with GTP, which I added in Coot(0.9.8). When refining the following error message pops-up : "Fatal problems interpreting model file: Number of atoms with unknown nonbonded energy type symbols:4 Please edit the model file to resolve the problems and/or supply a CIF file with matching restraint definitions, along with apply_cif_modifications and apply_cif_link parameter definitions if necessary". Checking the log file I found that the problem seems to be hydrogen atoms from these ligands Number of atoms with unknown nonbonded energy type symbols: 4 "HETATM 6499 H5' GTP A 501 .*. H " "HETATM 6502 H5'' GTP A 501 .*. H " "HETATM12939 H5' GDP B 501 .*. H " "HETATM12940 H5'' GDP B 501 .*. H " Including the corresponding .CIF files (dowloaded from PDB) did not solve the problem and the same error popped. Since I'm in the initial stages of the refinement I'm running phenix with bindividuals. Could anybody save my day giving me some light into this issue? Cheers, Diego

.cif file has 'UNK' auth_asym_id
by Kevin M Jude 14 Mar '25

14 Mar '25

I’ve finished refining a structure with three protein chains A, B, C. The pdb file looks ‘normal’ to me, but when I inspect the .cif file written by phenix, the auth_asym_id for chains B and C is ‘UNK’. label_asym_id is correct for all chains. I’m not really sure what the difference is between the auth_ and label_ fields. When I try to perform actions on the .cif file, I get duplicate atom label errors. Here’s a few example lines from the .pdb and .cif files, where auth_asym_id is field 6 and label_asym_id is field 16 ATOM 460 OXT PRO A 59 5.272 55.689 31.481 1.00 52.63 O ANISOU 460 OXT PRO A 59 6541 6212 7244 1448 1260 96 O TER ATOM 461 N ALA B 2 39.292 61.974 39.403 1.00 67.81 N ANISOU 461 N ALA B 2 7118 8729 9916 -1711 -388 2066 N ATOM 460 OXT .

Pdb validation report via phenix
by Stachowski, Tim 12 Mar '25

12 Mar '25

I’ve always found the phenix.get_pdb_validation tool to be super helpful to gauge where my refinements are relative to the PDB, especially since I work mainly through the command line. But sometime around late last year, the R-free metric stopped being calculated (probably related to “EDS: FAILED”). Is there a way to bring this part of the tool back – or does anyone have a work around they can share? I’m running the command like: phenix.get_pdb_validation_report final-coot-3_refine_001.reflections.cif final-coot-3_refine_001.cif with version: phenix-2.0rc1-5599 Thanks Tim -- Tim Stachowski, PhD St. Jude Children’s Research Hospital ________________________________ Email Disclaimer: www.stjude.org/emaildisclaimer Consultation Disclaimer: www.stjude.org/consultationdisclaimer

Refining the structure of Ribosome and the system crash
by Rajnandani Kashyap 12 Mar '25

12 Mar '25

Hello Everyone I am trying to run jobs in phenix (real space refinement alignment with the other modelling jobs), but the system always crashes, and refinement doesn't complete. This is the structure of ribosome, and I am wondering what to do to get through the refinement. Is there any specific parameters I should be using. I tried to change the processors to 15 for a 20-processor computer. Let me know. Thanks in advance. FYI: There is no error message in the log.

Ion placement (anomalous) + occupancy refinement
by miha.pavsic＠fkkt.uni-lj.si 07 Mar '25

07 Mar '25

Hi everyone, I have a dataset from a protein that contains 2 Ca2+ binding sites. The Ca2+ loaded protein was crystallized in the presence of Tb3+ which at one site mostly replaced Ca2+, however at the other site the Tb3+/Ca2+ ratio appears to be much lower (judging from anomalous map; data collected at 1.3 Å wavelength, MR for phasing). The occupancy sum of Tb3+ and Ca2+ at each of the two sites is strongly believed to be 1. While I am aware of the ion placement option in phenix.refine, I am not so sure how to refine the partial occupancies using anomalous data, if possible. Many thanks for any hints, Miha

AKM in Phenix
by lucas.santosouza＠outlook.com 07 Mar '25

07 Mar '25

Hi everyone, Is there still support for the generation of Average Kick Maps in Phenix? I am using both versions 1.21.2-5419 and the nightly build 2.0rc1-5555. I added kicked=True to the maps.params, but phenix.maps gives me "Unused parameter definitions: maps.map_coefficients.kicked (file "maps.params", line 53)". I also cannot see the "Kicked map" check box in the Create Maps GUI. Cheers, Lucas

Refine partially occupied ligand in active site containing chloride ions
by Stephen.carr＠rc-harwell.ac.uk 06 Mar '25

06 Mar '25

Dear phenix bb, I am trying to refine a ligand in the active site of my protein where the ligand occupancy is ~50%. The empty active site contains two chloride ions and the residual density from these ions is very prominent when the model is refined with the ligand alone. I would like to refine the model with both the ligand and chloride ions present and have been trying to do this with altLoc flags but so far with no luck. I'm assuming that since the Cl ions more-or-less directly overlay atoms from the ligand positional refinement keeps pushing them out of the density. I'm sure there is a simple way to get around this and I would be grateful for any suggestions.

Then, I tried to follow this guide to install gromacs_cryo_fit. However, I got stuck at the "Install using a provided script" step. Do I need to install GROMACS separately before proceeding? Any tips would be greatly appreciated! Many thanks, Omar

About d99
by Roberto Battistutta 25 Jan '25

25 Jan '25

Dear Phenix people, In "New tools for the analysis and validation of cryo-EM maps and atomic models” (ActaD 2018), it is reported that "map sharpening can affect d99 (Fig. 9g) but it is rather insensitive to masking (Fig. 9h).” I have a case where d99 increases a lot with masking, as shown in the screenshot below (from Mtriage). On the other hand, FSC decreases. What does this mean? Can it be attributed to the fact that there is a strong scatterer in the molecule (a heavy atom) that strongly influences the intensity of the map? Are there other possible explanations (preferential orientation for example)? What is the best way to handle such maps? Thank you for the attention. Best, Roberto. Roberto Battistutta Associate Professor Department of Chemical Sciences University of Padua via Marzolo 1, 35131 Padova - ITALY tel. +39.049.827.5262 fax. +39.049.827.5829 roberto.battistutta(a)unipd.it

André Mitschler, former crystallography engineer in the BSI department, Strasbourg
by Alexandre OURJOUMTSEV 24 Jan '25

24 Jan '25

Sorry, my previous e-mail left with a wrong subject… Sacha = = = = Dear all, for those (I expect, many of you) who knew André Mitschler, I resubmit the message below. Sad news. It was a great and non-trivial person. With best wishes, Sacha Urzhumtsev = = = = From: Valerie LAMOUR <lamourv(a)igbmc.fr<mailto:[email protected]>> Sent: Friday, January 24, 2025 4:23 PM Subject: André Mitschler, former crystallography engineer in the BSI department André Mitschler est décédé le 5 Décembre, à l’âge de 83 ans. André était un cristallographe expérimental hors pair. Il a débuté en recherche dans le laboratoire du Prof Weiss où il a eu la charge du premier diffractomètre à RX de l’époque. En 1967, a entamé une fructueuse collaboration avec Dino Moras qui a pu bénéficier de son expertise et son adresse expérimentale pour sa thèse de 3e cycle. Leurs liens ne se sont jamais rompus. En 1981 Il a rejoint le laboratoire de cristallographie de Dino, nouvellement créé à l’IBMC. Il y a effectué le reste d’une fructueuse carrière d’ingénieur CNRS qui, en 1994, s’est poursuivie à l’IGBMC, un nouvel institut créé à Illkirch avec un important soutien de l’industrie pharmaceutique. En 1996, il a rejoint le groupe d’Alberto Podjarny, pour travailler dans la détermination de la structure de l’Aldose Reductase humaine. Les cristaux diffractaient à une résolution extrêmement haute (0.6 Angstroms). La mesure des données a demandé des nouveaux développements et l’utilisation des meilleures lignes synchrotron du monde. André était à la hauteur du défi, avec la capacité de passer de longues heures à monter et tester expérimentalement des cristaux. Il pouvait travailler 72 heures d’affilée dans le synchrotron d'Argonne National Lab. Le travail a culminé en 2008, avec la publication d’un mécanisme enzymatique inattendu. En 1999, il a obtenu la médaille de Cristal du CNRS, en reconnaissance de ses travaux en cristallographie expérimentale. André était aussi un passionné de l’histoire militaire, et a fait une carrière dans l’armée jusqu’à rang de colonel dans la cavalerie. Sa passion par la recherche, sa force de travail et son dévouement pour l’excellence expérimentale sont un exemple à suivre par tous les jeunes chercheurs. //// André Mitschler passed away on December 5th at the age of 83. André was an outstanding experimental crystallographer. He began his research career in Professor Weiss's laboratory, where he was responsible for the first X-ray diffractometer at the time. In 1967, he started a fruitful collaboration with Dino Moras, whose doctoral work benefited greatly from André's expertise and experimental skill. Their professional ties endured throughout their lives. In 1981, André joined Dino’s newly established crystallography laboratory at IBMC, where he spent the remainder of a productive career as a CNRS engineer. In 1994, he continued his work at IGBMC, a new institute in Illkirch supported by the pharmaceutical industry. In 1996, André joined Alberto Podjarny’s group to work on determining the structure of human aldose reductase. The crystals diffracted at an exceptionally high resolution (0.6 Å), which required innovative developments and access to the world's most advanced synchrotron beamlines. André rose to the challenge, demonstrating his ability to spend long hours preparing and experimentally testing crystals. He worked tirelessly, including 72-hour shifts at the Argonne National Laboratory synchrotron. This effort culminated in 2008 with the publication of an unexpected enzymatic mechanism. In 1999, André was awarded the CNRS Crystal Medal in recognition of his contributions to experimental crystallography. André was also a military history enthusiast and pursued a parallel career in the army, rising to the rank of colonel in the cavalry. His passion for research, tireless work ethic, and dedication to experimental excellence remain an inspiration for young researchers.

Error opening REEL and ligand refinement in Coot
by Marian Oliva 17 Jan '25

17 Jan '25

Dear all, I posted this problem a couple of days ago through phenix help mail address but I got no answer (not sure if it was delivered properly). Maybe here I am luckier. I have recently upgrade my machine to Ubuntu MATE 1.26 and re-install all crystallography software I often use, including Phenix version dev-5493. I am working in a structure of a protein bound to a new ligand. I built the ligand with chemDraw, get the SMILE, get a universal SMILE string in cactus.nci.nih.gov <http://cactus.nci.nih.gov/>, and used eLbow for ligand restraints generation and optimization (using default parameters). First problem. When I try to open the ligand in REEL. Phenix crash with the following message in the terminal libGL error: MESA-LOADER: failed to open nouveau: /usr/lib/dri/nouveau_dri.so <http://nouveau_dri.so/>: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri) libGL error: failed to load driver: nouveau libGL error: MESA-LOADER: failed to open nouveau: /usr/lib/dri/nouveau_dri.so <http://nouveau_dri.so/>: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri) libGL error: failed to load driver: nouveau libGL error: MESA-LOADER: failed to open swrast: /usr/lib/dri/swrast_dri.so <http://swrast_dri.so/>: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri) libGL error: failed to load driver: swrast The program 'main.py' received an X Window System error. This probably reflects a bug in the program. The error was 'BadValue'. (Details: serial 39668 error_code 2 request_code 152 minor_code 24) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) Second, when I open the structure in Coot (0.9.8.95) from Phenix and try to perform real space refine zone to the ligand, the attached window pops-up. Is this because I did something wrong during the installation? Is there a bug I am not aware of? Any help will be really appreciate. Many thanks in advance, Marian

Hi everyone, I am using mmtbx.ringer via phenix-1.21rc1-5127 to explore ED changes from END/RAPID maps. While it’s possible to provide volume scaled maps, it does seem possible to provide noise maps from END/RAPID is that correct or am I missing sth.? Related: setting gui=true enables to graphically browse through the results, it does not seem to be possible to automatically save all these plots. Is it possible to activate this?

Error phenix refine with ligands
by miriam.cavinato＠unimi.it 07 Jan '25

07 Jan '25

Hi everyone, I am trying to refine my model containing a ligand (a thiophene -like molecule with a 7 carbon atom cycle attached). I create restraints with ready set utility or directly with eLBOW, then I use phenix.refine and I get this error: "fatal problems in interpreting model file: number of atoms with unknown nonbonded energy type symbols: 12 Please edit the model file to resolve the problems or/and supply a CIF file with matching restraint definitions, along with apply_cif_modification and apply_cif_link parameter definition if necessary". Another problem is that as soon as I try to open REEL or open any result to check restraints, Phenix crashes... I was wondering if someone has the same issue and can help me figure it out! Thanks in advance Best regards Miriam

Dear Colleagues, Happy New Year!! We are writing to share information about the upcoming West Coast Structural Biology Workshop, which is scheduled for March 23-26, 2025 at its traditional location, the picturesque Asilomar Conference Center in Pacific Grove, CA. The conference website can be found at: https://wcsbw2025.macromolecules.xyz/. The WCSBW is a bi-annual meeting that showcases the latest methods, developments, and discoveries in structural biology, including X-ray Crystallography, Cryo-EM, NMR, and other methods. We strongly encourage anyone interested in method development and solutions to technical challenges in structural analysis to attend, even if you're not from the west coast. Importantly, the WCSBW aims to highlight the work of trainees, so all oral presentations (except keynotes) will be given by students and postdocs. The 26th edition of this meeting will include: * Opportunities to connect with leaders in the field, exchange practical advice, and stay at the forefront of structural biology advancements. * Exciting oral research presentations and engaging poster sessions focusing on the contributions of students and postdocs. * Inspiring keynote presentations, featuring Prof. Bil Clemons from Caltech, and Dr. Junko Yano from Lawrence Berkeley National Lab. * A 2-hour workshop hosted by the Phenix developers, detailing the use of new tools for structure determination and analysis. * A networking session with scientists from west coast biotech companies for students and postdocs who are entering the job market. * Good company and beautiful views of the pacific ocean! Some details about the conference are included below, and more information is available at our website (see link above). Please note that the registration deadline is Feb. 7, 2025. We hope to see you at Asilomar in March! -Mike Thompson (UC Merced) and Alec Follmer (UC Davis) P.S. We ask for your help in sharing this announcement with any students, postdocs, staff, colleagues, collaborators, or friends that might be interested. Thanks! Conference Details: March 23-26, 2025 at Asilomar Conference Center in Pacific Grove, CA Visit the conference website at: https://wcsbw2025.macromolecules.xyz/ Registration: https://book.passkey.com/event/50870517/owner/10793795/home Registration fee is $200, plus lodging fees (meals included). Attendees need to book their lodging accommodations at Asilomar when registering for the conference. Both single and double occupancy rooms are available. If you do not have a roommate and would like us to pair you with one to lower costs, or if you would like to register for the conference and arrange your own accommodations offsite, please contact us at wcsbw2025(a)gmail.com<mailto:[email protected]>. Abstract Submission: https://wcsbw2025.macromolecules.xyz/registration/ All oral presentations at the WCSBW, except for the keynotes, will be given by trainees.

Handling of modified nucleotides in ribosome structures
by christian.steinmetzger＠imbim.uu.se 19 Dec '24

19 Dec '24

Dear community, I'm trying to work with a published ribosome structure (PDB 7K00, https://www.rcsb.org/structure/7k00 ) for example in phenix.combine_focused_maps or phenix.real_space_refine. Of course this structure contains a lot of modified residues and the monomer library in a fresh Phenix installation (version 1.21.2-5419) does not handle these out of the box. Since a lot of publications have used 7K00 as a starting point for their work in Phenix and since the current CCP4 monomer library plays nice with this structure I would not have expected this. Am I missing something in my Phenix setup to make it recognize such "common" modified residues in a ribosome or do I indeed need to generate parameters myself using AceDRG, eLBOW, Grade2 etc.? In the latter case, could I simply swap out the stock Phenix monomer library for the one from CCP4 as a drop-in replacement or would that be a bad idea? Thank you! Christian

Hello All. I got a nice 2.45 Angstrom map from cryo em data. I checked handedness, map model fitting on the chimera and opened in the coot. It looks nice. Can you please give me suggestions about the Phenix refinement steps. Thanks Iram
