Dear Tom I am trying to run phenix.cut_out_density but I seem to be unable to select the map_coeff_labels: viscount:~/sharpfiles/logfiles/Japanin-ID29-Phaser714.15> phenix.cut_out_density cycle_best_13.pdb eden_flat_55.0pc.mtz << EOF map_coeff_labels="FBshasol SIGFPsha PHIBshasol FOMshasol" EOF The output (see below) says I did not give SIGFP and it also picks the default F,PHI and FOM from columns 4,5,6 What am I doing wrong?

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.

phenix.phaser params.eff output directory
by G Y 26 Jul '11

26 Jul '11

Dear all, I am writing a script for phenix.phaser. The keyword "output_dir" seems not work. In params.eff file I give it a line like: solution = None output_dir = /home/.../somedir/ keywords { general { root = "PHASER" title = "[no title set]" verbose = None debug = None mute = None xyzout = ON hklout = ON jobs = 2 } But I can not generate output file in the specified directory(somedir in the above case). The output files are always put in current working directory. Did I choose a wrong keyword to do this? What would be the correct way? Any answer would be appreciate greatly. Many thanks. regards, GP

mr_rosetta with fixed solutions for other chains
by Bard, Joel 26 Jul '11

26 Jul '11

Hi- We have data for a crystal where two of three components have high homology search models and can be found with straightforward phaser runs but the third component has much weaker homology to anything in the pdb. Is there a way to provide the solution for the first two components and let mr_rosetta work on the third? Thanks, Joel

cif file for internal bond with one of two alternative conformations
by Daqi Tu 26 Jul '11

26 Jul '11

Hi, I have a structure of drug bound to a protein. The drug has two alternative conformations, in which one of them has an internal bond making it a cyclic compound. How do I refine a structure like this? What modification should I do to its cif file, which I generated using elbow without the internal bond. Thank you. Daqi Tu (sorry if I have double posted.)

phenix.phaser params.eff labin problem
by G P 25 Jul '11

25 Jul '11

Dear all, I am now writing a script for phenix.phaser. In the input file params.eff there is a keyword labin which corresponds to the labels inside input mtz files. The important columns in my ccp4 mtz file are FP, SIGFP. I edit the line of labin as: labin F=FP SIGF=SIGFP when running the script, it returns me: Syntax error: expected "=", found "F" (file "params.eff", line 9) So, I changed it like: labin=FP SIGFP when running, it gave me the message: Sorry: Couldn't find array FP SIGP in file I also tried: labin="FP" or labin = "FP SIGFP" or labin="labin F=FP" and so on. With nothing it can find the right columns. My mtz file should be not problem, I checked with mtzdmp, the columns FP and SIGFP were there and with phenix GUI this file works well. Would someone know exactly how to edit this line in params.eff? Many thanks! GP

Alternate conformer and HOH clashes

Thanks guys... What about waters, do they follow the same ALTLOC rules? I have a high res data 1A and I see lots of things... Ill probably bother you again with some questions as I keep refining. Best, Yuri -- Yuri Pompeu

Alternate conformer and HOH clashes
by Yuri 25 Jul '11

25 Jul '11

Dear All, I am having trouble refining multiple conformers that would clash into a neighbouring side chain that also has an alternate conformer. An attempt to clarify: Lets say a Tyr residue has conformation A1, but also moves into a position B1. In postition B, its side chain would clash into a neighbour Phe A2. However this Phe has another conformation B2. Bottom line, B1 and B2 would not clash, neither would A1 and A2. Any other combo (A1 B2, etc...) would clash. When I model it all in I see problems... I encounter the same situation with partially occupied HOHs. Whats the best way to deal with this Thank you -- Yuri Pompeu

phenix.phaser PATH problem
by G P 21 Jul '11

21 Jul '11

Dear all, It's long story: At beginning, I have phenix installed. I do not have CCP4 installed. Then I run "phenix.phaser params.eff" to call phenix run phaser from script params.eff. It works well. Then, I installed CCP4 with its own phaser inside. Then I run again "phenix.phaser params.eff". The computer start to import files (should be some libraries and supporting files, not input data) from CCP4 installation directory. It seems so strange for me. And because some of the .so files in CCP4 directory are for 32bit, phenix.phaser gave me error message: wrong ELF class: ELFCLASS32 and refused to keep running. I guess I could solve this problem by copying the same .so file in phenix directory into CCP4's directory. What I really want to know is why this happen. Is that the installation of CCP4 changed some kinds of PATH variables for phenix? How could I fix by giving a right path again? I would appreciate to any help. Thanks a lot guys! Best regards, GP

phenix.phaser multiple models
by G Y 21 Jul '11

21 Jul '11

Dear all, I want to give several input pdb (searching model) at same time and let phaser run MR separately on each of them. I found I can do this by first "Add ensembles" at Ensemble tab and then "Add search" at Search procedure tab then link the correct ensemble ID. However, there is just one output result for the best solution. Is there anyway to get all solutions in separate .mtz and .pdb files for different searching models? Many thanks! regards, G

Phenix TLS refined model feeding into next round of refinement
by Daqi Tu 21 Jul '11

21 Jul '11

Hi, I used to think after one round of Phenix TLS refinement, if I need to do further refinements after correcting couple residues, I need to take out the ANISOU records from the pdb file. The reason is if not, all protein atoms might be applied anisotropic individual B factor refinement in the next round. Yesterday, I made a "mistake" directly feeding the pdb file from the previous TLS refinement into the next one. Seems it is fine. Is that true Phenix automatically recognize what I wanted, that is, TLS only, not anisotropic individual B factor refinement? Thank you. Daqi Tu

How the sharpening were performed in PHENIX.
by zhangh1＠umbc.edu 20 Jul '11

20 Jul '11

Hi, I was trying to do a B-factor sharpening using phenix GUI CreatMaps utilities. The output for the sharpened maps contains 2FOFCWT and PHI2FOFCWT columes, so I think they are sigmaA weighted 2Fo-Fc maps. But from Brunger's paper, the sharpening coefficients seems directly applied on Fo, and I wonder what happened before we get the 2mFoDFc maps. Or, the sharpening coefficients have been applied to the 2mFoDFc maps? Thanks for any information! Hailiang
