The phenix autobuilder does not find buccaneer

Dear all, I have Buccaneer 1.5.0: partyring:~/Projects/Japanin/autoBUSTER> $CBIN/cbuccaneer <B><FONT COLOR='#FF0000'> <html>  <hr> <pre> ############################################################### ############################################################### ############################################################### ### CCP4 6.1: cbuccaneer version 1.5.0 : 28/05/10## ############################################################### User: pietro Run date: 10/ 1/2011 Run time: 17:18:57 and yet the phenix autobuilder fails - saying I need 1.3.0 or higher (see below) What environment variable is being checked and what should I set for the phenix autobuilder to be able to detect buccaneer? Thanks Regards Pietro **************************************** AutoBuild Input failed Sorry, the necessary version of BUCCANEER does not seem to be available..

Thanks a lot! phenix.tls is the tool to convert between total and residual ADPs. It can recognize Refmac and phenix.refine formats of TLS records. phenix.model_vs_data does this internally to compute correct R-factors and ADP statistics. phenix.fmodel takes the PDB file as is, so it is your responsibility to provide the correct input B-factors.

Displaying electron density in PyMol
by Michael Thompson 09 Jan '11

09 Jan '11

Hi All, Does phenix have a utility that will allow me to produce an electron density map that can be opened in PyMol, similar to the "FFT" utility in ccp4? Thanks for the help, Mike Thompson -- Michael C.

autobuild
by Page, Rebecca 09 Jan '11

09 Jan '11

Dear phenix community. We would like to 'fix' the residues of our current protein model, and use Autobuild (perhaps via rebuild-in-place=false, which is what we've been trying) to add missing residues to our current model . However, our efforts thus far have only resulted in models that get rebuilt from scratch. Is it possible to just 'add' residues to a current structure using Autobuild? If so, is someone could share the correct command with us, we'd be very appreciative. We can't seem to find it. Thanks in advance, Rebecca

Accessing the CCP4 monomer library in Coot opened from Phenix
by Joseph Noel 09 Jan '11

09 Jan '11

Hi All, Having trouble getting Coot loaded by Phenix to access monomers such as DTT, glycerol, etc I assume through the CCP4 monomer library. If I insert the following in the phenix file, start_coot.sh: DYLD_LIBRARY_PATH=/Applications/ccp4-6.1.13/lib:$DYLD_LIBRARY_PATH export DYLD_LIBRARY_PATH will Coot now access the monomer library?

error on Autobuild GUI on new version (1.7.629)
by Young-Jin Cho 07 Jan '11

07 Jan '11

Hi Phenix developers, I recently installed new version of phenix(phenix-1.7-629) FYI. I chose this installer version phenix-installer-1.7-629-intel-linux-2.6-x86_64-fc3.tar as my computer indicates 2.6.18-194.17.4.el5 x86_64 after uname -rm command. Everything was ok until I started AutoBuild program. Somehow it keeps giving me following error messages on my GUI window: ******************************************************************************** Sorry, a subprocess has failed... END OF LOG FILE /amnt/datnew/yjcho/RUN_FILE_2.log : ImportError: numpy.core.multiarray failed to import Possibly this subprocess is run on a machine with different architecture than the main process? ******************************************************************************** *************ERROR ENDING ******************* I would thank if you can help me out from this problem. Thanks in advance, Young-Jin

anisotropic refinement gui more than one chain
by Christian Roth 06 Jan '11

06 Jan '11

Dear all, I want refine a structure with several chlorides and want refine these chlorides anisotropic. I use the GUI for the setup and manipulate the eff file just before it starts. To my surprise my constrained group definitions are used, but my anistropic refinement definitions are removed I incorporated it as followed: adp { individual { isotropic = None anisotropic = "chain a" anisotropic = "chain f" anisotropic = "chain Y" anisotropic = "chain T" anisotropic = "chain U" anisotropic = "chain z" anisotropic = "chain d" anisotropic = "chain g" anisotropic = "chain e" anisotropic = "chain V" anisotropic = "chain X" anisotropic = "chain n" } but in the log the following is stated: adp { individual { anisotropic = "chain a" } Why are all the other definitions gone? And if I defined it wrong, how I have to define it correctly? The current version I use is 1.6.4-486 Thanks Christian

Questions about phenix.refine with twin_law
by Keitaro Yamashita 06 Jan '11

06 Jan '11

Dear Phenix developers, I'm working with pseudo-merohedrally twinned data (fraction 45%), using Phenix-dev-616. I have three questions about phenix.refine with twin_law. (running on the command line) During refinement with twin_law, the log file says x-ray target function is set to "twin_lsq_f". Does it mean, we cannot use maximum likelihood target for twinned data? If so, is it recommended to refine without twin_law at first several cycles? When I tried to refine using the model refined without twin_law, the target function was still ml, not twin_lsq_f although I specified twin_law. Is this a bug? When I used twin_law option, in the table "R-free likelihood based estimates", "Scale factor" were None in all resolution bins. Cannot scale factor be calculated during twin refinement? Thanks in advance and Wishing you the best holidays, Keitaro

How to get a statistics of sidechain&mainchain Bfactors?
by 商元 05 Jan '11

05 Jan '11

Dear all, I used TLS+ADP refinement to get the final structure model, after that I used phenix.model_vs_data to get the statistics for table1. However there is no B factor statistics in the output. Can I get the overall B factor by just simply averaging the B factors of each residue in the output text? Then how can I get the B factor value of the sidechains and that of the mainchain? Thanks and regards, Yuan SHANG Hong Kong
