Phenix version 1.7-650 and coot
by Leonid Flaks 31 Jan '11

31 Jan '11

Hi! I just installed phenix version 1.7-650 on fedora 14 64-bit and noticed that if I start coot from within phenix interface, most of the icons on the right hand side of the coot window are not displayed. There is a lot of messages like this: Error loading icon: Couldn't recognize the image file format for file '/usr/share/coot/pixmaps/residue-info.png' for png and svg files in the console window. I can see all of the icons if I start coot directly. I am using coot version 1.6.2-pre1 rev 3213 which is installed on 64-bit fedora 14 as a rpm file. I did not see this issue on a phenix version 1.6.4-476 with the same version of coot. Thanks, Leon -- Leonid Flaks Phone: (631) 344-2682 Fax : (631) 344-2741

phenix.mr_rosetta paths
by Ben Eisenbraun 31 Jan '11

31 Jan '11

Hi, I'm testing Rosetta 3.2+PHENIX 1.7-650, and in the phenix.mr_rosetta output, I see: Checking rosetta paths: rosetta binary: /programs/l/rosetta/3.2/rosetta_source/bin/mr_protocols.default database_dir: /programs/l/rosetta/3.2/rosetta_database script_dir: /programs/l/rosetta/3.2/rosetta_source/src/apps/public/electron_density pilot_script_dir: /programs/l/rosetta/3.2/rosetta_source/src/apps/pilot/frank/ In the script directory, the C++ files were not built along with the regular Rosetta build. Do those need to be compiled for the target platform? Also, the pilot_script_dir is empty. Is there supposed to be something in there? Thanks. -ben -- | Ben Eisenbraun | SBGrid Consortium | http://sbgrid.org | | Harvard Medical School | http://hms.harvard.edu |

translation/rotation matrix
by Yogesh Gupta 31 Jan '11

Dear PhenixBB members, I calculated two maps one using 3 wavelengths Se to 4.2A, and 3 wavelength Ta to ~3.9A for ~100kDa protein in space group P62 with 1 molecule in A.U. These crystals are non-isomorphous. Ta MAD map is better than Se MAD map. There is no model available at this point. Is there a way to transform Se sites accurately to the Ta map? Thanks for your help. Yogesh -- -------------------------------------------------- Yogesh K.

It turned out this problem exists in phenix 1.6.4 under fedora 14 also - just nobody noticed it on the current setup! Fedora 14 is about 2 month old and we are coming out of the winter shutdown. We had a mixture of fedora 12 and 13 before and did not see that problem. Of course, python version has been changed to python-2.7 for Fedora 14. Console output for all 3 conditions are saved. I'll mail them to you directly - I don't want to flood the list. Thanks, Leon -- Leonid Flaks Phone: (631) 344-2682 Fax : (631) 344-2741

Is there an easy way to specify unwanted cis-peptides and remove them in refinement or with torsion dynamics or SA? Tim

Re: [phenixbb] Global refinement parameters - use statistical model for missing atoms
by Joseph Noel 30 Jan '11

30 Jan '11

Hi Pavel! Thanks for the reply. It does seem to be working though in the current version as long as I choose advanced level in the gui. Does it make sense though that it is lowering my Free-R? Also, the upshot is that the Fo-Fc maps are much flatter. I can see waters to build but only in the 2Fo-Fc sigmaa weighted maps so it does certainly seem to be doing something. Anyway, I look forward to the docs on it when you officially release it. Seems useful! Best- Joe ___________________________________________________________ Joseph P.

selection string for omit maps
by Alexandra Deaconescu 28 Jan '11

28 Jan '11

Hi: I am new to Phenix and I am currently using the GUI. I would like to compute a sa-omit map by leaving out residues 204-209 of my chain C. In the GUI, what is the proper syntax for this selection string? I tried a few obvious formats but the jobs failed.

Global refinement parameters - use statistical model for missing atoms
by Joseph Noel 28 Jan '11

28 Jan '11

Hi All, Does it make sense that when the box for "use statistical model for missing atoms" is picked under the GUI's "Global refinement parameters options" that one might obtain "better" Free-R values? I seem to be seeing that for a 2.3 A refinement of a crystal with a monomer of 550 residues in the asymmetric unit and 68% solvent content. When I uncheck the box I get about a 3% increase in Free-R. Is there more information about what this option is actually doing and when it might be useful to employ? Joe ___________________________________________________________ Joseph P.

REMINDER - EMBO 2011 Practical Course - ESRF-EMBL, Grenoble, France, 6 - 10 June 2011
by Daniele de Sanctis 28 Jan '11

28 Jan '11

Hi all, Just a reminder, as deadline is approacing DEADLINE TO APPLY FEBRUARY 28th COURSE ANNOUCEMENT EMBO 2011 Practical Course - Exploiting Anomalous Scattering in Macromolecular Structure Determination ESRF-EMBL, Grenoble, France, 6 - 10 June 2011 The EMBO 2011 Practical Course on Exploiting Anomalous Scattering in Macromolecular Structure Determination will be hosted by the ESRF in Grenoble, France from 6 to 10, June 2011. The course aims to impart the theoretical and practical basis for the 3-dimensional structure determination of bio-macromolecules using Anomalous Dispersion techniques (SAD & MAD) to young scientists who intend to apply these methods in macromolecular crystallography. Through a series of lectures, software demonstrations, practicals on the ESRF beamlines and tutorials, participants will get insights into all aspects of the structure determination process including beamline instrumentation, data collection and processing, heavy atom substructure determination, phasing and model building. There will also be sessions focusing on automated structure solution procedures and newer methods. Additional sessions will include presentations of distinguished structures solved with these techniques. The number of participants is limited to 20 and the deadline for application is February 28th, 2011. Additional information, course programme and instructions to apply to the course can be found in the course webpages: http://cwp.embo.org/pc11-03/ -- ἀρετή --------------------------------------- Daniele de Sanctis, PhD Structural Biology Group ESRF, Grenoble, France Tel 33 (0)4 76 88 2869
