phenix.mr_model_preparation_1.8-1069 can't parse hhr

Dear all, I was trying to run MR_rosetta, but encountered a problem: my hhr files can't be parsed. GUI does not recognize files as HHR and phenix.mr_model_preparation_1.8-1069 exits with the error below. I can't figure out what does it want from me. Any help will be greatly appreciated.

mr_rosetta and Condor
by Dmitry Rodionov 05 Sep '12

05 Sep '12

Good day! I am trying to get a bunch of OS X 10.6 workstations managed by Condor to work together on an mr_rosetta project. I am new to batch systems and rather confused. The Phenix manual states: "Single file system required for mr_rosetta All files are stored on a single file system that must be accessible to all jobs." What exactly has to go on the network share and how would I make the execution nodes aware of it? Could somebody please share some information on a working setup of this sort? Thanks! Best regards, Dmitry

phenix/ccp4 monomer library compatibility
by Wulf Blankenfeldt 05 Sep '12

05 Sep '12

Dear all: this may have been asked a thousand times, but: are the ccp4 standard monomer libraries incompatible with phenix.refine, and if yes, is there an easy way to resolve this? I am refining a structure with an FMN, which I build with the "get monomer" option in coot. Unfortunately, phenix.refine doesn't like it and throws it out. Using a cif generated with elbow, on the other hand, has chirality errors (which I can fix...) and isn't liked by coot (0.6.2), which refuses to refine the ligand. Thanks in advance for your help, Wulf -- Prof. Dr. Wulf Blankenfeldt NW-I, 2.0.U1.09 Universitaet Bayreuth fon: +49-(0)921-55-2427 Lehrstuhl fuer Biochemie fax: +49-(0)921-55-2432 Universitaetsstrasse 30 e-mail: wulf.blankenfeldt [at] uni-bayreuth.de 95447 Bayreuth web: www.biochemie.uni-bayreuth.de Germany

B factor refinement in recent versions of phenix
by "Weiergräber, Oliver H." 30 Aug '12

30 Aug '12

Hello, I am experiencing a weird problem with B factor refinement (individual, isotropic) in phenix.refine. The dataset reveals a Wilson B factor of about 23 A². However, if phenix.refine is allowed to run for a number of macrocycles, the mean B value of the model drops continuously to about 9 A². In the end, several atoms are getting values of 0.00! There are no obvious abnormalities in the electron density, and R values are quite good. I was able to dig out an old phenix version (1.7.1) and found that this one behaves perfectly well: mean B around 26 A² (slightly above Wilson B, as is observed frequently) and minimum B around 10 A². So obviously something has happened between versions 1.7.1 and 1.8 ... The latest dev release (1143) shows the same behavior as version 1.8. I should say that this structure is somewhat peculiar (pseudomerohedral twinning plus twofold NCS), but again, the old phenix version handles that without problems. Moreover, the tendency for unreasonably low B factors has been observed recently for a more "conventional" structure in our lab. Any ideas what might be causing this and how to revert to the original behavior?

Phaser and PTNCS - bug fixed in latest builder for Phenix?
by Rafael Lemos Miguez Counago 29 Aug '12

29 Aug '12

Dear all, I noticed on the Phaserwiki webpage (news section) that there is a bugfix (dated 14th of August/2012) for Phaser as the "Packing test was incorrectly applied to reoriented molecules where there was PTNCS". I had a look in the "changes" file, but could not find if this bugfix is part of the latest Phenix installer (dev-1143) or not. Could anybody clarify this point for me? Thanks a lot. Best wishes, Rafael.

Dear All, Early bird registrations for the Asian Crystallography Association Conference and the Bragg Symposium close this Saturday. You can register for one or both events. **** ** ** The one-day Bragg Symposium on Thursday the 6th of December may be of particular interest as it will specifically address the scientific and historical aspects associated with the centenary of Lawrence Bragg’s explanation of X-ray diffraction. ** ** To register, visit: **** ** ** http://www.sapmea.asn.au/conventions/crystal2012/index.html Kind regards to read this newsletter in your browser click here <http://www.sapmea.asn.au/conventions/crystal2012/emails/enews_01.html>**** [image: cid:[email protected]]**** AsCA 12/CRYSTAL 28 *Conference Newsletter***** Volume 1, May 2012**** Invitation to attend**** *A Joint Meeting of the Asian Crystallographic Association (AsCA), ** Society of Crystallographers in Australia and New Zealand (SCANZ) and the BRAGG Symposium, * November 2012 marks the centenary of the founding of X-ray crystallography by Lawrence Bragg, a field in which he and his father, William, made pre-eminent contributions that were recognised by the award of the Nobel Prize for Physics in 1915. William was the Elder Professor of Physics at the University of Adelaide from 1886 to 1909 and Lawrence was born and educated in Adelaide.**** To celebrate this important anniversary, the legacy of the Braggs’ discoveries in X-ray crystallography and the insights that they have provided into the structure of matter, a combined scientific meeting of the Asian Crystallography Association and the Society of Crystallographers in Australia and New Zealand is to be held in Adelaide from the 2nd to 5th of December 2012. The Conference will be followed by the Bragg Symposium at the University of Adelaide on the 6th of December 2012 that will explore some of the historical context and personal links to the Braggs' work as well as present some of the broader scientific and social impacts of the Braggs' work.

Funky message on phaser MR
by Rafael Lemos Miguez Counago 27 Aug '12

27 Aug '12

Dear all, I am getting this message when running Phaser-MR in Phenix (1.8-1069): "Warning: Resolution of data does not achieve (half) expected LLG target: placement of one/first ensemble will be very difficult" The data scales/merges OK. – 99% complete at 2.2A, Rmerge 8.4%. TNCS is detected by Xtriage and Phaser tries to account for that. Coincidently (?) my molecular replacement solution is not looking very good. Any ideas? Best wishes, Rafael.

HB_score in Ligand Identification
by Brad C. Bennett 23 Aug '12

23 Aug '12

Hello to all- Where can I find a description of what "HB_score" is and how it is calculated in the Ligand Identification program in Phenix? I'm assuming this is a metric for hydrogen bonding capability/propensity of a fit ligand based on distance and angle to model atoms. I have an output rank list of the top 20 ligand fits, ranked by Z-score. The HB_score is all over the place: low = -0.59, high = 77.96, most are between 0-10. I think I understand the correlation coefficient and Z-score but how does the HB_score fit in with these? I can't find this in the documentation or in the Terwilliger et al. (2007) Acta D reference. Somehow I've "lost" the log file, so maybe the information is in there. Thanks in advance! Brad C.

real space correlation
by Bradley Hintze 22 Aug '12

22 Aug '12

Hey Phenix team, I am trying to get real space correlation measurements for 1eao and ran into a problem. $ phenix.fetch_pdb --mtz 1eao $ phenix.real_space_correlation 1eao.pdb 1eao.mtz Multiple equally suitable arrays of observed xray data found. Possible choices: 1eao.mtz:FOBS,SIGFOBS 1eao.mtz:F(+),SIGF(+),F(-),SIGF(-) Please use .labels to specify an unambiguous substring of the target label. Looking in the options for phenix.real_space_correlation it is unclear how to specify the labels for the reflection file. Any assistance on this would greatly be appreciated.
