Berkeley Server Outage (Starting October 26th)
by Paul Adams 25 Oct '19

25 Oct '19

Dear Colleagues, yet again, as a result of the increased frequency of wildfires in California the power company is taking steps to reduce risk under certain weather conditions. This entails shutting down electricity to regions that are experiencing dry windy conditions. We have been informed that the weather this weekend meets their criteria for a shutdown in our part of the Bay Area. Therefore several of the Berkeley servers will be shut down this weekend and will return later the following week. This will affect: - The Phenix web site (http://phenix-online.org/) - The DIALS West web site (http://dials.lbl.gov/) - The CCI web site (http://cci.lbl.gov/) - The Structural Biology Technology Portal (http://technology.sbkb.org/) Bug reports and emails requesting help should be queued and we will receive them once the servers are back online. We apologize for any inconvenience.

real space refine and nonbonded_weight
by Cheung, Alan 25 Oct '19

25 Oct '19

Dear Developers A structure we refined back in 2017, using phenix.real_space_refine on a cryoEM map @ 3.7A (version 1.11.1–2575) produces a clashscore of ~8 but the exact same refinement run with the latest phenix (version 1.17.1) generates a clashscore of ~22. Our refinements with the latest version on other EM structures tend to generate pretty high clashscores too. I think i've tracked this down to the nonbonded_weight parameter, which defaults to 1000 in the older version, and to 100 in the latest version. At which version did the default change, and is there a reason for it? I couldn't find it in the changelog. Alan

Yeast microtubule model
by Sebastiano Pasqualato 24 Oct '19

24 Oct '19

Dear all, I’m addressing to people working in the microtubule field. Has someone created, or knows where I could find, a pdb file of the yeast microtubule, or a portion of it? I’m interested in studying the contacts between subunits within the lattice. I know one could generate that using yeast tubulin dimers, but I don’t know exactly how. If someone has already done that and is willing to share it, that would be extremely helpful. Thanks a lot in advance, ciao, S PS: sorry for the cross posting to members of both bulletin boards. -- Sebastiano Pasqualato, PhD Biochemistry and Structural Biology Unit Department of Experimental Oncology European Institute of Oncology IFOM-IEO Campus via Adamello, 16 20139 - Milano Italy tel +39 02 9437 5167 fax +39 02 9437 5990

Phenix-RSR model fit issue in CS-Map
by pramod kumar 23 Oct '19

23 Oct '19

Dear Experts, I have a map generated through cryosparc (ab initio-reconstr and homo-refine at 3.7A* FSC and sharpened in Scipion and separately in EMAN2). I have build the initial pdb through BALBES which has perfect validation parameters and nice fitting in the map (with the mtz output) but the co-ordinates are shifted from the true origin of CS-map. I used phenix-RSR to fit and refine, but validation results remained too far to accept the model as good solution and also a small region entered in wrong nearyby densities. So far following independent and downstream approaches I have taken:- In phenix; dock in map, map to model, rigid body refine followed by real space refine (with both .map and converted .mtz), using only chain A-map boxing and model generation through NCS. I have tried chimera fit for entire assembly and also only one chain in boxed map and full map but still the validation remained far from acceptable values and a small region in wrong neighboring density. Please help. -- Best regards, Promod

high B Factor after real space refinement against a cryoEM map
by Keda Zhou 17 Oct '19

17 Oct '19

Dear all, I am trying to do the real space refinement for my model against a 5.0 angstrom cryoEM map. All parameters look pretty good except the B factor. The mean of the B factor is close to 400. I am just wondering whether the low resolution makes the B factor this high. Does anyone have any idea or suggestion on the high B factor during real space refinement? Is it possible to reduce it? What is the actual meaning of this B factor? Thanks in advance. cody

Masked FSC estimation failure
by ze li 12 Oct '19

12 Oct '19

Hello: I have three cryo-ET full maps, not in halves, to estimate their resolutions. I intended to estimate the resolution of the maps with the high-resolution models in the PDB databank. Is it the best to get a map to model FSC estimation at 0.5 cut-off? I calculated three maps with cryo-EM module in Phenix, but only one gives the masked and unmasked curves, the other two only have the unmasked results.I tried many times but failed to figure out the questions of these two maps. What is the possible reason for them? Or Is there any other ways to get the unmasked and masked FSC? Thank you for your help. Sincerely, Ze

positional restraints in real_space_refine?
by Daniel Larsson 08 Oct '19

08 Oct '19

Hi all, I'm working on a cryo-EM reconstruction where I have some flexible low-resolution elements (RNA double helices). They have different orientations relative to my reference model, but I would like to model them in the approximately correct position. I've tried real_space_refine with morphing and simulated annealing, but neither accomplish what I want. Now I'm thinking of cutting out these helices and manually position them approximately where I want them. But I fear that this will case headache at the "joint". Is it possible to use the manual positions as a reference for positional restraints, but use the original model as the reference for the torsion angles. Is this possible with real_space_refine? Or is there a better way of refining this structure? Regards, Daniel När du har kontakt med oss på Uppsala universitet med e-post så innebär det att vi behandlar dina personuppgifter.

reference torsion restraints for nucleic acids in real_space_refine
by Daniel Larsson 07 Oct '19

07 Oct '19

Hi all, In phenix.real_space_refine, I'm using a reference model for torsion restraints for a RNA/protein complex. I noticed in the log file under the section "Adding Reference Model Restraints (torsion)" that only the amino acid residues and some modified nucleotides are listed in the "Reference Model Matching Summary" but not the standard nucleotides. Does this mean that they are not restrained? I checked the _initial.geo file and there are no torsion restraints for the standard nucleotides in the "Reference torsion angle restraints" section. Are they not supported by default? My workflow was this: run ready_set on the initial model and then supply real_space_refine with a reference model and the ready_set cif file with the ligands.

Base-pair restraints and high resolution cryoEM maps
by Stephen Cusack 07 Oct '19

Dear All, (1) Is it possible to add RNA base-pair restraints into Phenix Real-space-refinement of a lowish resolution cryoEM structure? If so how? (2) We are also lucky enough to have some impressively high resolution cryoEM maps (2.4 A average) which show among other things hundreds of water molecules. I was wondering whether Phenix Real-space-refinement was really adapted to high resolution, e.g. it uses grouped B-factor refinement and has no water handling options (putting them in manually is a pain and you always miss some). How have other people dealt with these issues ? thanks for any help Stephen Cusack -- ********************************************************************** Dr. Stephen Cusack, FRS Head of EMBL Grenoble Group leader in the structural biology of protein-RNA complexes and viral proteins ********************************************************************** Email: cusack(a)embl.fr, stephen.cusack(a)embl.org Website: http://www.embl.fr Tel: (33) 4 76 20 7238 Secretary (33) 4 76 20 7123 Fax: (33) 4 76 20 7199 Postal address: EMBL Grenoble Outstation, 71 Avenue des Martyrs, CS 90181, 38042 Grenoble Cedex 9, France Delivery address: EMBL Grenoble Outstation, Polygone Scientifique, 71 Avenue des Martyrs, 38000 Grenoble, France **********************************************************************

Re: [phenixbb] Figure of merit from refinement
by Alexandre OURJOUMTSEV 03 Oct '19

03 Oct '19

Dear Andre, (I repeat here the same message that I've just sent through the ccp4bb; sorry for answering late) I would strongly advice you to look at the article by Lunin and Skovoroda (Acta Cryst, A, 1995) that addresses exactly your question: https://scripts.iucr.org/cgi-bin/paper?vs0124 The authors remind a very important point that after model refinement ML phase errors are strongly underestimated if using all reflections, as that was done in the original works (see references in the article). While the same ML estimates work perfectly for unrefined models, that's not the case for refined ones, as was observed yet in the beginning of 80ths. These authors show then that using the test-set of reflections (the same as for R-free) is crucial to get the correct phase error estimates and respective FOMs for all cases, as this is implemented now in modern refinement programs, e.g. phenix.refine. See also the article by Pannu & Read (Acta Cryst, A, 1996) https://onlinelibrary.wiley.com/doi/pdf/10.1107/S0108767396004370 A more recent important article on this topic is that by Praznikar and Turk (Acta Cryst, D, 2009) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4257616/ who discuss what can be done if a statistically significant test set of reflections is not available. I hope this helps you. I am ready to answer you further eventual questions (probably, in a private correspondence).

Potential Berkeley Server Outage (September 23/24)
by Paul Adams 21 Sep '19

21 Sep '19

Dear Colleagues, as a result of the increased frequency of wildfires in California the power company is taking steps to reduce risk under certain weather conditions. This entails shutting down electricity to regions that are experiencing dry windy conditions. They are predicting that Monday or Tuesday this coming week (September 23/24) might meet their criteria for a shutdown in the Bay Area. Hopefully this is just a worst case prediction and nothing will happen. However, there is a possibility that the Berkeley servers will be down for some time during that period (duration unknown). This will affect: - The Phenix web site (http://phenix-online.org/) - The DIALS West web site (http://dials.lbl.gov/) - The CCI web site (http://cci.lbl.gov/) - The Structural Biology Technology Portal (http://technology.sbkb.org/) Bug reports and emails requesting help should be queued and we will receive them once the servers are back online. We apologize for any inconvenience.

Selenium Nucleic Acids
by SeNA Research Institute 06 Sep '19

06 Sep '19

Dear Chemical and/or Structural Biologists, To serve our community, we have developed the selenium-atom specific derivatization of nucleic acids for crystallographic studies. We have discovered that virtually without any perturbations, the incorporated Se-atoms on nucleic acids can (I) rationally solve the phasing problem and (II) significantly facilitate nucleic acid crystallization (even with higher resolution and much larger crystals) in many cases, including protein-nucleic acid complexes. Currently, we are looking for collaborators and would be happy to offer free samples of Se-DNAs and Se-RNAs for your structure-and-function investigations. If you are interested, please contact us at SeNA(a)senaresearch.org Thanks, Mike SeNA Research Institute Email: SeNA(a)senaresearch.org Web: www.SeNAresearch.org http://www.senaresearch.org/

Each talk will have a full 10 minutes of discussion (15 minutes for Keynote talks). Moderators for each session will help include students and postdocs in the discussion. Students and postdocs will have many opportunities to talk with more senior researchers at conference breaks, meals, receptions and poster sessions. The last conference was a huge success (see https://bit.ly/2Gfkm4t and https://bit.ly/2Gg39rm) and this one is looking great (see https://cvent.me/4kq9P) We have a super group of speakers (keynote speakers are Ilme Schlichting, David Stuart, Erica Ollmann Saphire, Robert Stroud, Suzanne Scarlata, David Eisenberg, Wayne Hendrickson, Yvonne Jones, Eva Nogales, and Tom Blundell) After the main conference there will be an optional Phenix workshop with lectures and hands-on sessions on using Phenix for crystallography and cryo-EM. You can register now at https://cvent.me/4kq9P !

CCTBX documentation questionnaire
by Dorothee Liebschner 20 Aug '19

20 Aug '19

Hi everyone, During this year's ECM computing school, it came up that the CCTBX does not have a lot of documentation. This seems to be a major reason why people don't use it, even if they would like to employ the libraries. We would like to find out which parts of the CCTBX are the most interesting for users. We certainly cannot provide extensive documentation for the entire toolbox, but we can see what we can do once we know the main areas of interest. So if you were in the situation of wanting to use the CCTBX but decided to stay away from it because the documentation was non-existent or obscure, please let us know by filling out the questionnaire below (it's anonymous): questionnaire CCTBX documentation <https://forms.gle/9RawJFfHyEvhCVVP7> Best wishes, Dorothee -- Project Scientist, Molecular Biophysics and Integrated Bioimaging Lawrence Berkeley National Laboratory 1 Cyclotron Road, M/S 33R0345 Berkeley, CA 94720 Tel: (510) 486-5709 Fax: (510) 486-5909 Web: https://phenix-online.org

Dear all, On Friday, August 16, our servers will be shut down starting at 4:00 pm Pacific for scheduled maintenance in our building. We expect that the servers will be available by 10:00 am Pacific on Sunday (8/18) at the latest. This will affect, - The Phenix web site (http://phenix-online.org/) - The DIALS West web site (http://dials.lbl.gov/) - The CCI web site (http://cci.lbl.gov/) - The Structural Biology Technology Portal (http://technology.sbkb.org/) Bug reports and emails requesting help should be queued and we will receive them once the servers are back online.

Re: [phenixbb] [cctbxbb] CCTBX documentation questionnaire
by Dorothee Liebschner 16 Aug '19

Hi Ben, Yes there is a reason: Checkbox option (multiple answers) does not support redirecting the answer (I wanted that feature). Your options: - You can choose "other" and list the libraries in question and describe what is problematic for each. - You can fill out the questionnaire several times (choose a different module each time) - You can write us (or me) an email and tell us details Cheers, Dorothee On Fri, Aug 16, 2019 at 12:21 AM ben.williams(a)diamond.ac.uk < ben.williams(a)diamond.ac.uk> wrote: > Dear Dorothee, > > Is there a reason for only allowing a single choice of library in the > questionnaire?
