Dear All, I have installed Rosetta on Linux machine. When i am issuing the command " rosetta.build_phenix_interface" it is giving me following error scons: Building targets ... scons: *** [build/src/release/linux/2.6/64/x86/gcc/4.4/python/libObjexxFCL.so] Implicit dependency `/usr/local/lib/libdl.so' not found, needed by target `build/src/release/linux/2.6/64/x86/gcc/4.4/python/libObjexxFCL.so'. scons: building terminated because of errors. Would you please give me your valuable suggestions to successfully carry out the Rosetta refinement. Thank you Appu

Rosetta Refinement problem
by Appu kumar 09 Jul '15

09 Jul '15

Dear All, I have installed Rosetta successfully on Linux machine and after installation it say building done. While refining a structure with "phenix.rosetta_refine" it is giving following problem End of input processing Sorry: The RosettaScripts executable could not be located. Please add the appropriate directory to your PATH environment variable, or set the variable ROSETTA_BIN to point to it. In my .cshrc file i have setup the path as follow setenv PHENIX_ROSETTA_PATH /home/appu/2014_09_29_NSLS_X29/rosetta_bin_linux_2015.25.57927_bundle setenv ROSETTA_BIN /home/appu/2014_09_29_NSLS_X29/rosetta_bin_linux_2015.25.57927_bundle/main/source/bin setenv phenix /home/appu/software/phenix/phenix-1.9-1692 setenv ROSETTA3_DB /home/appu/2014_09_29_NSLS_X29/rosetta_bin_linux_2015.25.57927_bundle/main/database I would appreciate any help and suggestions in executing the Rosetta refinement Thank you Appu

Problem with python while running Autobuild
by Tam＠em.uni-frankfurt.de 09 Jul '15

09 Jul '15

Dear all, I am currently facing a problem of python while running the Autobuild in Phenix. phenix.autobuild data=data1.mtz model=model.pdb seq_file=protein.dat rebuild_in_place=False \ composite_omit_type=iterative_build_omit then it stopped with error Error in `/home/mauricetam/software/phenix-1.9-1692/build/intel-linux-2.6-x86_64/base/bin/python2.7': free(): invalid next size (normal): 0x0000000003e100a0 *** I wonder what's wrong with it.

problems with rosetta
by Benny Belviso 09 Jul '15

09 Jul '15

Dear all, I am trying to use rosetta with the Phenix Gui (Phenix is installed on Debian). I have downloaded the tar.gz file named "rosetta_bin_linux_2015.25.57927_bundle" that contains source and binary files. Becouse the tar.gz contains pre-compiled files, I have not compiled rosetta again (however, I have the same problems also in the case of tar.gz containing source after the compilation). According to the instructions showed on http://strucbio.biologie.uni-konstanz.de/ccp4wiki/index.php/Phenix#Installa… I have setup my environmental variables in .bashrc as: export PHENIX_ROSETTA_PATH=/home/bbdanilo/program/rosetta_bin_linux_2015.25.57927_bundle export ROSETTA3_DB=$PHENIX_ROSETTA_PATH/main/database However, by opening MR-Rosetta on Phenix GUI, I get a first warning message that says me that rosetta directory seems to be not correct. By running rosetta, the program says that it is not able to find PHENIX_ROSETTA_PATH. I have tried to change the path also in the "Directory setup" by typing /home/bbdanilo/program/rosetta_bin_linux_2015.25.57927_bundle as directory for rosetta path /main/source/bin as Rosetta binary directory name mr_protocols.linuxgccrelease as binary of rosetta In this case, the program says that does not find the binary for rosetta (it requires mr_rosetta.default, instead I should use mr_protocols.linuxgccrelease). What am I doing wrong? Any help is welcome. Thanks. Danilo This message and any attachment are intended solely for the addressee and may contain confidential information.

Re: [phenixbb] on determination whether a protein is a monomer or complex by phenix
by Valerie Pye 07 Jul '15

Hi Smith, Your solvent content is most likely the 66% one (if you have diffraction to about 1A there's a chance it could be 33%.....in which case try to solve it with Balbes (ccp4)). You can not tell what the crystal packing is like until you solve the structure! Even if you know how many molecules you have in your a.s.u. you can not tell if the contacts are formed because of crystal packing or oligo formation! Its much better to look at your protein in solution for this (as i said before!)

Weird problem of Coot fetch PDB&Map using PDB_redo
by Xiao Lei 07 Jul '15

07 Jul '15

Hi All, Today I found one weird problem of coot. I have coot installed in different platforms, I have coot 0.8.1 version in Ubuntu 15.04 and coot 0.8.1 version in Mac OS X 10.10.3, and I also have wincoot 0.8.1 in Windows 8.1. When I tried to fetch pdb&map using EDS, coot in all three platforms works very well. However, when I tried to fetch pdb&map using PDB_redo, only the windows wincoot works, which shows "successfully read coordinates...". The coot in mac and Ubuntu failed to fetch and shows "failed to read coordinates file...". I do not think the problem comes from PDB_redo as I tried to fetch the same pdb to compare coot in three platforms, only wincoot works well. I do not know if anyone else has this problem and how to fix it. Thanks ahead. Xiao

on determination whether a protein is a monomer or complex by phenix
by Smith Liu 07 Jul '15

07 Jul '15

Dear All, Suppose I have got a mtz file, and I know the aa sequence of the protein from which I got the crystal and the corresponding mtz file, will you please tell me which phenix function (program) can tell me whether my protein crystal was formed by protein monomer or by protein complex, and if formed by protein complex, how many subunits existing in the complex? Best regards. Smith

phenix rosetta refine
by Jens Kaiser 06 Jul '15

06 Jul '15

Hey there, who would be the person to talk about setting up phenix.rosetta_refine? I tried our SBgrid installation with overrides to "nightly" for phenix and rosetta; I tried a clean install of rosetta and phenix - production version and nightly's in all combinations - and all combinations of compiling (rosetta first, then rosetta.build_phenix_interface, phenix first, then rosetta.build_phenix_interface). The problem is that "phenix.rosetta_refine" seems to run, and produce a log file that looks reasonable, but geometry params are worse than with an ordinary refine. I think I tracked it down to the fact that the "rosetta_XX.sh" files are empty, and rosetta actually does not run. Any help is welcome - and any support will be extended. Cheers, Jens

Re: [phenixbb] Optimal settings for finding NCS from density
by Terwilliger, Thomas Charles 05 Jul '15

05 Jul '15

Hi William, For find_ncs_from_density the shape of the molecule itself is not so important. What matters is if there is some local part of the molecule that is recognizable in both copies. So I would try default parameters first. I assume you did that and it didn't give you a useful answer...so then I would do these things: 1. try many locations : n_center_use=20 This is the best option...it will try 20 times using density at 20 different locations to search. If you have an older version of phenix you may need to download a nightly build to do this. 2. Try varying the resolution 3. Try varying the angular spacing of the search (delta_phi) All the best, Tom T ________________________________ From: CCP4 bulletin board [CCP4BB(a)JISCMAIL.AC.UK] on behalf of William Chao [William.Chao(a)CRICK.AC.UK] Sent: Friday, July 03, 2015 10:24 AM To: CCP4BB(a)JISCMAIL.AC.UK Subject: [ccp4bb] Optimal settings for finding NCS from density Dear all, What would be the best settings to look for NCS using phenix.find_ncs_from_density on an elongated (~150A) molecule?
