changing project directory
by Jens Kaiser 16 Aug '11

16 Aug '11

Hi all, I have project data on external hard drives. As I use several different file systems, and mount the drives in random order, I cannot rely on the device being mounted in the same mount point. In order to keep paths consistent, I link the project directories into my home. This used to work fine. I recently created a project, and phenix seemed to have used the real path instead of the link-path (That's not the problem, yet). I tried to manually edit ~/.phenix/project_db.phil, but it still tries to write in a non-existing directory. A naive 'grep -R "disk-1" ~/.phenix' did not reveal any obvious file either. Where can I change the directory associated with a project {per,con}sistently? Thanks for your time, Jens

modelling of disordered protein
by intekhab alam 16 Aug '11

16 Aug '11

Hi I solved an RNA polymerase structure in its native as well as in complex with chemical ligands (2.5A and C2 space group). The structure has been solved by MR a protein having 60% identity. The ASU has a monomer and dimer. Recently i complexed this RNA polymerase (protein A) with a highly flexible protein B and got the crystal. These crytsal also have C2 space group (resolution 2.3A) having similar cell parameters but has psudotranslation (17.34%). I tried MR using rosetta. HHpred server selected one of my deposited structure in PDB (3NAI 100% identity) as template. Rosetta MR gave 2 solutions one of which is dimer-monomer arrangement while the other one is a trimer. The values of these solution are below. Solution 1: trimer REMARK Log-Likelihood Gain: 10662.548 REMARK RFZ=16.5 TFZ=14.4 PAK=0 LLG=959 TFZ==23.2 RFZ=0.0 TFZ=48.9 PAK=0 LLG=3195 TFZ==55.6 (& TFZ==52.6) LLG+=(3191 & 7008) LLG=7024 TFZ==72.0 LLG=10663 TFZ==90.1 Solution 2: Monomer and dimer in ASU REMARK Log-Likelihood Gain: 2120.965 REMARK RFZ=39.7 TFZ=21.9 PAK=0 LLG=811 TFZ==37.7 LLG=2121 TFZ==43.6 REMARK ENSEMBLE ensemble_1 EULER 204.07 178.91 204.37 FRAC 0.499 Map and model fits well in both the cases with R and R free 26 and 30% respectively. My queries: 1. which one will be the correct solution? Is it possible that the protein B has resulted in the trimeric arrangement? 2. i cannot find any continuous 2Fo-Fc map for proteinB, but there are some continuous density at 0.7 which is very ambiguous. how can i improve the map so that i can model some fragments of my proteinB (protein B is of 73 amino acids and is predicted to be highly flexible and disordered. ((biochemical as well as bioinformatical analysis done )) I already have tried autobuild but it fails to build even a partial fragment of the proteinB. Kindly suggest how to proceed , or how can i prove the presence of protein B in the structure. Regards INTEKHAB ALAM LABORATORY OF STRUCTURAL BIOINFORMATICS KOREA UNIVERSITY, SEOUL

Unexpected Occupancy refiniement for ligands...
by Yuri 13 Aug '11

13 Aug '11

Hey, So I am finishing up a model at 1.5 A and I tried to refine my ligands (3) and waters (468) in addition to altloc residues. The residues refine as expected e.g OccA + OccB = 1.0 and all atoms in A have OccA and all the atoms in B have OccB. My ligands on the other are being refined as the following: HETATM 6867 C1 MLA L 3 32.357 -28.612 7.978 0.93 23.77 C C HETATM 6868 O1A MLA L 3 31.209 -28.949 7.502 0.85 24.79 C O HETATM 6869 O1B MLA L 3 32.454 -28.160 9.141 0.70 22.70 C O HETATM 6870 C2 MLA L 3 33.553 -28.727 7.095 1.00 25.46 C C HETATM 6871 C3 MLA L 3 34.774 -28.070 7.627 0.92 28.45 C C HETATM 6872 O3A MLA L 3 34.830 -27.664 8.808 1.00 30.15 C O HETATM 6873 O3B MLA L 3 35.775 -27.948 6.840 1.00 30.23 C O HETATM 6874 HC21 MLA L 3 33.321 -28.281 6.139 1.00 30.56 C H HETATM 6875 HC22 MLA L 3 33.760 -29.776 6.943 1.00 30.56 C H Each atom is getting an individual occupancy assigned, which physically is impossible :) Any light? Could it be my selection syntax? Corrigendum: I think I sent a bug email last night about an error when writing mtz files in refinement. It was an accident. My naming convention was bad, thats why it crashed. Sorry -- Yuri Pompeu

R/Rfree discrepancy Phenix vs Refmac
by Sabine Schneider 12 Aug '11

12 Aug '11

Hello, I am refining a structure at 2.1A solved by MR. For curiosity I'm testing things like 'shaking' coordinates, simulated annealing, refinement Refmac vs Phenix and so on, to see what influence that has on stats, maps etc. For instance after MR I did a bit of shaking the coordinates with pdbset (noise 0.1), followed by simulated annealing in Phenix. Phenix states after SA: Start R-work = 0.2671, R-free = 0.2992 Final R-work = 0.2312, R-free = 0.2666 When I use the output pdb of phenix directly in Refmac (with same mtz as input for Phenix) Refmac tells me: Initial R factor 0.2392 R free 0.2887 So I am quite puzzled about the discrepancy. Or can someone tell me if I made an error in reasoning somewhere? Thanks a lot for the help! Sabine

Intensity-Weighted Reciprocal Lattice
by Michael Thompson 05 Aug '11

05 Aug '11

Hello ccp4 & phenix BB members, I would like to view the intensity-weighted reciprocal lattice for several data sets that I have collected. (The data have been indexed, integrated and scaled with Denzo and Scalepack.) I was wondering if anyone could offer some advice on what might be the best and/or most practical way to do this? I know that there are several programs out there that can generate sections (i.e. 0,k,l) of the reciprocal lattice, such as LABELIT and xrayplot. Are there any other options for doing this, perhaps within ccp4 and/or phenix? I once saw someone give a presentation and they had a little video that showed a three dimensional section of the reciprocal lattice rocking back and forth, which was really cool. I liked this because I felt like it gave a much more holistic representation as opposed to viewing a bunch of individual sections. I don't know if there is an easy way to do this, or if this person somehow managed to create this 3D depiction from a series of sections. Any tips or recommendations would be appreciated. Thanks, Mike -- Michael C. Thompson Graduate Student Biochemistry & Molecular Biology Division Department of Chemistry & Biochemistry University of California, Los Angeles miket(a)chem.ucla.edu

adding hydrogens -> increasing clash score
by Tatyana Sysoeva 05 Aug '11

05 Aug '11

Hi! I have probably a very naive question - when one includes hydrogens into a refinement of a model build with data at ~3.6A clash score should not go up? I mean I am including hydrogens for a reason of improving the model quality when I cannot fit the sidechains into some density, etc. Can it be true that using default 3 macrocycles on a changed (reduced) model is not enough to minimize it? Thanks, Tanya

how to apply phi/psi helical restraints
by Daqi Tu 03 Aug '11

03 Aug '11

Hi, I was trying to restrain a relatively mobile region of my structure to be helical using Phenix secondary structure restraints. The result is very bad. It forces the N-O distance to be about 3A, but the phi/psi angles are all ugly. What is the way in Phenix I can apply phi/psi restraints just like in the old CNS, which had always worked nicely? Thank you. Daqi Tu

phenix.mr_rosetta
by Andreas Förster 02 Aug '11

02 Aug '11

Dear all, I've made the frightening plunge into the cold waters of Rosetta (3.3 this time) again, with an eye on using it with Phenix, and am sharing the joy. Things work, but: - Download rosetta_source and rosetta_database separately. The bundle doesn't contain all the files. - Compilation fails on RHEL 6.1 (gcc 4.5 issue) but sails on RHEL 5.5. - $PHENIX_ROSETTA_PATH must point to the Rosetta installation directory (where rosetta_source and rosetta_database sit). Don't be misled by the phenix.mr_rosetta documentation into setting $PHENIX_ROSETTTA_PATH (triple T). - all directories in the Rosetta installation must be made accessible to users find $PHENIX_ROSETTA_PATH -type d -exec chmod 755 '{}' \; Hope that helps someone.

new optimize weight

Hi, With Phenix dev-836, when optimize_xyz_weight and optimize_adp_weight are set to true, where can I find the optimal weights so I can directly put into the next run to save time (i.e. without optimizing any more). Previously it is a scale factor I can use for fix_wxc for example. But right now I can only see a weight factor. Thanks. Daqi

Re: [phenixbb] Third issue of Computation Crystallography Newsletter - Volume 2, Number 2
by Frank von Delft 01 Aug '11

01 Aug '11

Hi, just scanned through the article on automatic weight adjustment. If I had to summarise figures 1 and 2, I'd have to conclude that the latest weight optimization only occasionally produces better results than not doing it (fig 2); and that therefore the old optimization was considerably worse than doing nothing at all. Or have I misinterpreted it?

Phaser searching with density: how do I place my model on the solution?
by Pietro Roversi 31 Jul '11

31 Jul '11

Dear all, I succeded in finding a molecular replacement solution searching with the density I have in P43212 against a C2221 dataset, using the Phaser procedure documented in: http://www.phaser.cimr.cam.ac.uk/index.php/Using_Electron_Density_as_a_Model Question: what operators should I use for dmmulti now? Or put it another way, how do I put onto the C2221 placement my P43212 model? I tried using the Euler and xyz numbers fro0m the phaser sol file but they do not seem to produce a model that goes with the C2221 Phaser density. Any help is greatly appreciated Thanks Pietro

getting phenix and coot to talk on OSX
by Harry Greenblatt 31 Jul '11

31 Jul '11

BS"D Dear All, I see that CCP4 has a new version of coot for OSX that runs under X-windows. I'm not interested in using Fink, and Bill Scott's standalone binaries don't seem to work on my laptop, and we also have some machines at 10.5.x, and new versions of coot in that format are not available. But the CCP4 version wasn't built it to communicate with Phenix during a run. Is that functionality something that can be added easily post-facto?

C=O-D(+) and COOD restraints for phenix.refine
by Maxime Cuypers 28 Jul '11

28 Jul '11

Hello, Apologies if this problem has been asked previously, but i can t seem to find a solution online. I have added deuterium atoms in an exotic part of amide group (main chain) R2-C=O-D (+) bond and on a side chain Glu R-COOD to my pdb. i need to get a .cif that would account for it and work with phenix.refine. However, ready_set does not create a .cif file for it as it does not find unrestrained atoms. "No unknown residues" i have formatted the pdb the following way, adding DX for example (see ***): ATOM 778 N GLU A 51 8.057 40.510 -2.596 1.00 9.23 N ATOM 779 CA GLU A 51 8.846 41.709 -2.789 1.00 10.29 C ATOM 780 CB GLU A 51 8.151 42.937 -2.157 1.00 10.64 C ATOM 781 CG GLU A 51 6.672 43.097 -2.610 1.00 14.50 C ATOM 782 CD GLU A 51 6.543 43.007 -4.130 1.00 12.87 C ATOM 783 OE2 GLU A 51 6.056 42.014 -4.689 1.00 12.79 O ATOM 784 OE1 GLU A 51 6.987 43.967 -4.788 1.00 14.44 O ATOM 785 C GLU A 51 10.293 41.604 -2.286 1.00 8.42 C ATOM 786 O GLU A 51 10.961 42.627 -2.213 1.00 11.96 O ATOM 787 D GLU A 51 7.625 40.435 -1.776 1.00 10.15 D ATOM 788 DA GLU A 51 8.957 41.874 -3.812 1.00 12.62 D ATOM 789 DB2 GLU A 51 8.172 42.833 -1.173 1.00 11.93 D ATOM 790 DB3 GLU A 51 8.654 43.758 -2.380 1.00 13.79 D ATOM 791 DG2 GLU A 51 6.159 42.376 -2.149 1.00 11.66 D ATOM 792 DG3 GLU A 51 6.340 43.998 -2.326 1.00 14.27 D ***ATOM 793 DE1 GLU A 51 8.271 44.322 -5.268 1.00 30.00 D ATOM 850 N LEU A 56 20.084 37.831 -2.359 1.00 10.58 N ATOM 851 CA LEU A 56 21.370 38.483 -2.643 1.00 11.42 C ATOM 852 CB LEU A 56 21.801 39.360 -1.449 1.00 12.58 C ATOM 853 CG LEU A 56 20.783 40.461 -1.081 1.00 14.37 C ATOM 854 CD1 LEU A 56 21.278 41.264 0.152 1.00 16.71 C ATOM 855 CD2 LEU A 56 20.512 41.416 -2.257 1.00 17.46 C ATOM 856 C LEU A 56 22.415 37.441 -2.957 1.00 14.27 C ATOM 857 O LEU A 56 23.025 36.818 -2.093 1.00 30.34 O ATOM 858 D LEU A 56 19.954 37.597 -1.492 1.00 11.35 D ATOM 859 DA LEU A 56 21.249 39.065 -3.470 1.00 11.59 D ATOM 860 DB2 LEU A 56 21.898 38.760 -0.652 1.00 14.27 D ATOM 861 DB3 LEU A 56 22.681 39.834 -1.676 1.00 14.15 D ATOM 862 DG LEU A 56 19.925 39.988 -0.873 1.00 15.72 D ATOM 863 DD11 LEU A 56 20.622 41.969 0.365 1.00 17.87 D ATOM 864 DD12 LEU A 56 21.385 40.668 0.910 1.00 17.46 D ATOM 865 DD13 LEU A 56 22.131 41.691 -0.060 1.00 18.41 D ATOM 866 DD21 LEU A 56 19.968 42.175 -1.959 1.00 18.01 D ATOM 867 DD22 LEU A 56 21.384 41.721 -2.564 1.00 16.67 D ATOM 868 DD23 LEU A 56 20.043 40.956 -2.972 1.00 18.06 D ***ATOM 869 DX LEU A 56 22.482 36.144 -2.004 0.20 30.00 D I suspect i need to find a correct name for the D atoms, but i tried several already unsuccessfully. phenix.refine complains about 2 unrestrained atoms, the 2 D. Does someone know if there is a way to solve this issue or a workaround, please? thanks, Maxime
