Re: [phenixbb] Build Phenix from Source Code

I switched to version 1.8.4-1496 and this time the same error didn't occur. Also --python-shared/--with-rosetta flag works. But I ran it as # ./install --prefix=/usr/local/src --nproc=8 --no-gui --phython-shared then regenerate the dispatchers by running libtbx.refresh as shown in the message after installation. However, the installation is not complete, and if I source phenix_env.sh, the error message as below will show up: *************************************************************************************************************** bash: /usr/local/src/phenix-1.8.4-1496/bin/machine_type: No such file or directory bash: /usr/local/src/phenix-1.8.4-1496/bin/machine_version: No such file or directory bash: /usr/local/src/phenix-1.8.4-1496/bin/find-installation: No such file or directory *************************************************************************************************************** What else should I run to complete building phenix? PS. Because the first time I didn't append --python-shared flag, I build it again after deleting the original directory. I guess there might be files elsewhere that are changed, since I didn't have this error the first time.

HELP. semelno met refinement not working.
by Kenneth A. Satyshur 24 Apr '14

24 Apr '14

When I refine my seleno met residues in Phenix (1.8.4-1496) ALL my MSE are restrained to ONE conformer, in coot terms ptp #11 with a Chi 1 of 60 deg. This happens at the start of the second cycle when it does 'rsrl'. I can watch it happen in coot. POP! There is goes. Some of the MSE are in this conformation, but not all of them. This refinement is wrong, so how do I correct it? thanks kas -- Kenneth A. Satyshur, M.S.,Ph.D. Senior Scientist University of Wisconsin Madison, Wisconsin 53706 608-215-5207

BCA/CCP4 Summer School in Protein Crystallography at Diamond
by Airlie McCoy 24 Apr '14

24 Apr '14

Applications are now open for the BCA/CCP4 Summer School in Protein Crystallography to be held at Diamond (UK) from Tuesday 26th August to Sunday 31st August 2014. Applications close 1st May 2014. References are due by 8th May 2014. The BCA/CCP4 Protein Crystallography Summer School is intended for students and researchers new to crystallography. Its dual aims are to provide comprehensive training in crystallography and to promote best practise within the British crystallographic community. The lectures cover the gamut of techniques required for a structure solution, from protein expression through to structure validation. Intensively supervised computer tutorials enable students to relate the theory presented in the lectures to practice. Although CCP4 programs will primarily be used in these tutorials, the aim will be to approach crystallographic questions in a software-agnostic manner. There will also be a crystal manipulation and cooling workshop. Note that the course is scheduled during Diamond synchrotron downtime, so there will not be active data collection at the Diamond beamlines. For more information on eligibility, cost, and applications see: http://www.diamond.ac.uk/Home/Events/BCA-Summer-School.html Application form: http://extranet2.diamond.ac.uk/ISV/EventWidget/BCA/ApplicationsForm.aspx

inputing tNCS into phenix?
by Yarrow Madrona 23 Apr '14

23 Apr '14

Hello, I recently posted a question about stalled R-factors and and obtained excellent help resulting in the realization that I have tNCS even though it is not picked up by X-triage. I know the transformation matrix of one molecule onto another but I am not sure how to input this into phenix (both the translation and the rotation) to improve refinement. Is there a way to do this? I'm sorry if this has already been covered. -Yarrow

Trouble Refining Ligand in Phenix
by Chris Fage 22 Apr '14

22 Apr '14

Hi Everyone, I am trying to refine a structure with a phosphorylated amino acid. After refining in Phenix, the Fo-Fc density (green) overlaps the 2Fo-Fc density for all atoms of the derivatized amino acid in Coot, almost as if I had not built in the residue. I am loading a .cif for the derivative when I run phenix.refine. I have also tried ReadySet, but when I click the "Run in phenix.refine" button, I see the message Error interpreting command line argument as parameter definition: "refine_65-coot-2.metal.edits" RuntimeError: Unexpected end of output. Am I just seeing noise, or is Phenix not actually refining this portion of the model? I would appreciate any suggestions. Best, Chris

Hi Chen, "command not found" usually means the shell cannot find a particular command. It often can be fixed by sourcing the right setup commands. If you type: phenix.list does it also say "command not found"? If so, you just need to source the phenix version you want. When you install it phenix lists where this directory is...If you are on a mac you will say something like this: source /Applications/PHENIX-1.8.3-1479/Contents/phenix-1.8.3-1479/phenix_env and you can put that in your .cshrc file too (if you are using csh). Let me know if that doesn't do it! All the best, Tom T On Apr 21, 2014, at 10:53 AM, Chen Zhao wrote: Dear all, Hello!

Re: [phenixbb] Stalled refinement
by Dale Tronrud 19 Apr '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, In P21 the equivalent positions are: xyz; -x,y+1/2,-z. In matrix form the operation to transform chain A onto the symmetry image of A is: Transform A -> Symmetry related A /-1 0 0\ /x\ / 0 \ | 0 1 0 | |y| + |1/2| \ 0 0 -1/ \z/ \ 0 / Now let's assume there are two molecules in the ASU related by a perfect two-fold, axis parallel to the crystal screw axis, but with arbitrary translations perpendicular. The equation to transform chain B onto A is: Transform B -> A /-1 0 0\ /x\ /t1\ | 0 1 0 | |y| + |0 | \ 0 0 -1/ \z/ \t3/ Now, the question is "What is the transformation that takes chain B directly onto the symmetry image of A?" We can derive that by transforming B onto A and then transforming that by the crystal screw axis. Transform B -> symmetry related A /-1 0 0\ //-1 0 0\ /x\ /t1\\ / 0 \ | 0 1 0 | || 0 1 0 | |y| + |0 || + |1/2| \ 0 0 -1/ \\ 0 0 -1/ \z/ \t3// \ 0 / Now simplify: / 1 0 0\ /x\ /-t1\ / 0 \ | 0 1 0 | |y| + | 0 | + |1/2| \ 0 0 1/ \z/ \-t3/ \ 0 / / 1 0 0\ /x\ /-t1\ | 0 1 0 | |y| + |1/2| \ 0 0 1/ \z/ \-t3/ What we get is an identity operator with a translation. Note, I didn't make any other assumptions. Whenever you have space group P21 and two-fold ncs with the same symmetry axis direction you will get pseudo-translation. With your crystal the ncs matrix is not aligned with the y axis all that well. I haven't calculated it exactly but it seems to be about 10 deg away. That must be enough to wipe out the Patterson peak and the pseudo-translation check in xtriage. As a side note, you mentioned that you didn't think this was pseudo-translation because the translation was not 0.5. A translation of 0.5 could lead to pseudo-centering which is a special case of pseudo-translation. If you had that your crystal would be nearly space group C2 and half your reflections would be systematically weak and this can cause problems with the free R.

Hi Yarrow, of course the data quality will suffer but ultimately it depends on the amount of splitting - as long as the integration profile covers both parts then the total intensity is conserved, and recovered. I have seen many datasets with split reflections that were usable for MR and refinement. But I doubt that many of these would be suitable for experimental phasing. best, Kay Am 18.04.14 23:21, schrieb Yarrow Madrona: > Hi Kay, > > Looking at the data I can see that many of the spots are actually split. > I guess this may be causing problems in refinement if split spots are > integrated as a single spot? > > > On Fri, Apr 18, 2014 at 2:17 PM, Kay Diederichs > <kay.diederichs(a)uni-konstanz.de <mailto:[email protected]>> > wrote: > > It is a good idea to try several data processing programs in > difficult cases. > > BTW the latest MOSFLM can also integrate two (or more) lattices. > > Pls report your results. > > Kay > > > Am 18.04.14 22:59, schrieb Yarrow Madrona: > > Thanks Kay, > > XDS kicked out a lot of reflections.

Hi Yarrow, the problem is that during structure solution, many wrong paths may have to be followed until finally identifying the correct path. So the general answer to this kind of problem is: in some way, your parameterization of the experiment is wrong or incomplete. From what you write, data quality does not seem to be the problem. But: did XDS really integrate _all_ the reflections, or only a subset (say, every second reflection)? Check out http://strucbio.biologie.uni-konstanz.de/ccp4wiki/index.php/Refinement#what… If, after thorough attempts, you fail to find the solution, upload your current model, sequence and raw data frames to a Dropbox folder and post the link here - there may be people who succeed in processing the data nicely, or otherwise can identify the problem based on the data (rather than based on your description only).

There is no significant peaks for translational NCS. I also didn't see anything in the patterson map. However, the Multivariate Z score L-test gives 6.218. Also the observed Centric reflections are more intense than they should be but I don't suspect twinning in a monoclinic space group. -Yarrow On Thu, Apr 17, 2014 at 4:37 PM, Paul Adams <pdadams(a)lbl.gov> wrote: > > What does triage say about translation NCS? > > > On Thu, Apr 17, 2014 at 4:25 PM, Yarrow Madrona <amadrona(a)uci.edu> wrote: > >> Hello, >> >> I using the latest stable build of phenx.refine (1.8.4) I recently >> collected data, processed and obtained an MR solution using phaser.

DNA basepairing restraint refinement
by 李翔 18 Apr '14

18 Apr '14

Hi, I am working my low resolution data (6A) by MR and met a problem about DNA basepairing during refinement. I think so far everything looks OK except the bases flipped during the refinement. I added basepairing restraint for all bases, however, seems not help too much. Does anyone have experience on that? Sincerely, Xiang -- Li Xiang Department of chemistry, Purdue University Email：lixiang1642(a)gmail.com

Stalled refinement
by Yarrow Madrona 18 Apr '14

18 Apr '14

Hello, I using the latest stable build of phenx.refine (1.8.4) I recently collected data, processed and obtained an MR solution using phaser. I am stuck trying to refine with an Rfree sitting at 40% I really want to know if the high Rfree is due to poor data quality or if non-crystallographic symmetry involving a near perfect two fold rotation between the two molecules in the ASU could somehow impede refinement. Stats and other information is below. Thank you for any help you can give. -Yarrow Visually, the quality of the data is marginal at best (streaky/ice rings in many frames) despite good processing stats from XDS. Processing with mosflm or HKL2000 managed to index but failed pretty bad in integration and scaling. Phaser gave high TFZ scores for 2 molecules in the asu (see below). Density for a cholesterol like ligand shows up even though not present in the search model.

homology models in sculptor
by "Weiergräber, Oliver H." 15 Apr '14

15 Apr '14

Hello, I am using phenix.sculptor for modification of a homology model in a challenging case of molecular replacement. The input model is complete (except at the termini), i.e. it exactly matches the target sequence as defined in the alignment file. In this scenario, are there any caveats to consider with individual options in sculptor? Specifically, a quick test seems to indicate that the Schwarzenbacher algorithm for side chain pruning does not work, i.e. not a single atom is removed from the model, whereas the alternative "similarity" option leads to deletion of a few hundred atoms. I'm using sculptor from the command line, and the log file indicates my input is interpreted correctly. Best regards Oliver ================================================ PD Dr. Oliver H.

recovering the files from project directory
by Bishwa Subedi 14 Apr '14

14 Apr '14

Hi, I tried to use phenix in my personal computer for small checks and convenient use. I accidentally happened to make my project directory /user/XXX/Documents. Even though it was not the intended folder for running Phenix and later changed it to some other folders, I noticed that all my documents in that folder has disappeared (folder is empty). I do not see the files in trash folder as well. I assume this happened because of selecting documents as the project directory and phenix empties the folder before use, am I correct? If so is there any way to recover those files? Thanking you in advance. Best regards, Bishwa

GRC on Diffraction Methods: end July 2014
by Anastassis Perrakis 08 Apr '14

08 Apr '14

Dear all, We are getting closer and closer to the 2014 edition of my favorite Gordon Research Conference (https://www.grc.org/programs.aspx?year=2014&program=diffrac ) on Diffraction Methods in Structural Biology "Faster, Smaller, Better: Novel Technologies for Diffraction Experiments in Molecular Biology and Drug Discovery" , which this year will also feature before it starts the Gordon Research Seminars "Towards Integrative Structural Biology" (https://www.grc.org/programs.aspx?year=2014&program=grs_diff), targeting young scientists! Thanks to INSTRUCT (http://www.structuralbiology.eu) there will be four fellowships for young European researchers coming originally from an INSTRUCT member country or working in an INSTRUCT member country (http://www.structuralbiology.eu/resources/countries). Each fellowship will amount to 750 Euro, covering registration for both the GRC and the GRS, and all local expenses. It is a condition that you have to attend both the GRS and the GRC and submit a poster for both events. If you want to apply for such a fellowship, please send me an email reply (maintain the subject line please), including a single-page PDF file, a very short CV, an equally short abstract of your research, and a motivation statement explaining why you think this event is crucial for your career. Please include the email of your direct supervisor in the end of this letter, and a statement that she/he has agreed to cover the travel expenses for you to attend, if your fellowship application comes through. The deadline for receiving these letters is Wednesday 16 April at 12:CET (yes, thats less than a week from now! get writing!). The letters will be reviewed by an INSTRUCT panel, and the chosen four candidates will get a notification by the 8th of May! And, of course, I do take this opportunity to remind to everyone that the (almost) final program is on-line, we have an absolutely amazing group of speakers lined up, and the available places are filling up fast! So please remember to register on time! Looking forward to see you all at Bates College for what I trust you can make an exciting and memorable meeting! Best regards, Tassos PS If the file is not PDF, if its more than one page, if the characters you use are too small to read, etc etc, don't be too surprised if you do not get the travel fellowship award!
