MR: Apply rotation and translation to structure factors
by Shweta Kailasan 01 Feb '13

01 Feb '13

Hello, I am trying to use a cryo-EM map as a MR model for an Xtal data set. I have calculated structure factors for my map using SFALL. And also used rotcross and trans.com (from AMORE) to determine best possible rotation and translation solutions. Is there is a program/script available that can be used to apply those rotations and translation to structure factors ? Most programs start with a coordinate file (pdb) as a model whereas my initial model is a map. I tried to use Phaser but it didnot work out. Any help would be highly appreciated. Thank you. -S <peter.ramsumair(a)credit-suisse.com>

Problem getting Phenix and Rosetta working together
by Dale Tronrud 31 Jan '13

31 Jan '13

Hi, I would like to get mr_rosetta running on my CentOS 6.3 64 bit computer but I can't seem to get them connected. I'm probably doing something stupid/silly but I'm stumped. I've downloaded, installed and compiled rosetta3.4 in the folder /usr/local/rosetta3.4. There are a bunch of files in rosetta_source/bin and they are executable. However, typing the following commands shows my problem. [dale@athena tln]$ echo $PHENIX_ROSETTA_PATH /usr/local/rosetta3.4 [dale@athena tln]$ ls -l $PHENIX_ROSETTA_PATH total 156 drwxr-xr-x. 10 root root 4096 Mar 20 2012 Antibody drwxr-xr-x. 3 root root 4096 Jul 26 2011 foldit-3.4 -rw-r--r--. 1 root root 1115 Mar 25 2012 new_apps.note drwxr-xr-x. 25 root root 4096 Mar 20 2012 protocol_capture -rw-r--r--. 1 root root 460 Mar 25 2012 README.Copyrights -rw-r--r--. 1 root root 12 Mar 25 2012 README.version -rw-r--r--. 1 root root 3345 Mar 25 2012 release.note drwxr-xr-x. 19 root root 106496 Mar 25 2012 rosetta3.4_user_guide drwxr-xr-x. 9 root root 4096 Mar 25 2012 rosetta_database drwxr-xr-x. 61 root root 4096 Mar 20 2012 rosetta_demos drwxr-xr-x. 11 root root 4096 Jan 30 15:27 rosetta_source drwxr-xr-x. 7 root root 4096 Mar 27 2012 rosetta_tests drwxr-xr-x. 13 root root 4096 Mar 20 2012 rosetta_tools [dale@athena tln]$ phenix_regression.wizards.test_command_line_rosetta_quick Skipping phenix rosetta tests: rosetta build not available. I can try "mr_rosetta" itself but it just tells me that I need to set PHENIX_ROSETTA_PATH. What, in particular, is Phenix looking for to determine that Rosetta is installed? Dale Tronrud

Seats are still available for RapiData - the deadline is in 4 days for our course on Data Collection and Structure Solving at the NSLS.
by Robert Sweet 31 Jan '13

31 Jan '13

We will present RapiData 2013, the fifteenth offering of our popular course: Rapid Data Collection and Structure Solving at the NSLS: A Practical Course in Macromolecular X-Ray Diffraction Measurement The course will be held 21-26 April 2013: http://www.bnl.gov/RapiData/. Students could be at any level from advanced undergraduate to full professor. The course should accommodate 48 students total. We encourage all students to bring their own specimens for data collection, and to bring old data for the data-reduction and structure-solving tutorials. Please read the Course Announcement at http://www.bnl.gov/RapiData/. You'll see that many experts in the field will be available for lectures and tutorials. You'll find the application materials on the Course Application tab at this site. For the eleventh time we will hold a short lecture course on the fundamentals of crystallography for roughly five hours on Sunday 21 April. The body of the RapiData course really requires that students have a healthy knowledge of crystallography. For potential students who have some experience but are shaky about fundamentals, this course will help. There will be a small additional fee for the fundamentals course, to pay for Saturday night accomodations and food on Sunday morning and noon. Latin American Scientists: Several scholarships are available, from the International Union of Crystallography, to pay partial travel and subsistence costs for Latin-American students and junior faculty (under 40 yrs). Please apply for the course, and then contact R. Sweet (sweet(a)bnl.gov) if you are interested in applying for a scholarship.

Hirshfeld (rigid bond) test
by amakal＠chem.uw.edu.pl 31 Jan '13

31 Jan '13

Good Morning, I have a question concering ADP-s analysis and validation. Thanks to the recent discussion on this list I learned about the tools for general ADP-s statistics and average B-factor plotting in PHENIX. Has anyone ever tried to similarly document/visualize the values of the Hirshfeld's rigid bond test for macromolecules, using phenix/cctbx tools? I know the Hirshfeld's can be calculated during phenix refinement (there is this rigid_bond_test keyword), but I would like to analyze the values for the final model... With regards, Anna Makal

phenix.refine command line
by Simon Kolstoe 30 Jan '13

30 Jan '13

Hi guys, I'm just trying to install phenix on a students new macbook pro running OS10.8.2, and want to get phenix.refine working on the command line. I've put in: alias setphenix="source /Applications/PHENIX-1.8.1-1168/Contents/phenix-1.8.1-1168/phenix_env.sh" in the .bashrc which seems to execute OK (and already pointed the .bash_profile to .bashrc) however whenever I then type phenix.refine I get command not found. As this is the same setup that I have running on my own machine I am a bit confused as to what is happening! Thanks! Simon

Phaser with fixed solution
by Ursula Schulze-Gahmen 30 Jan '13

30 Jan '13

I am trying to solve a structure by molecular replacement in phaser using 2 model fragments. I think I may have placed the 1st fragment correctly. I don't quite understand how to best proceed with a fixed ensemble searching for the second fragment in phaser-MR. If I select "use partial solution from previous job", do I still need to read in the coordinates of that previous solution for one ensemble? And If I do, should I read in the starting coordinates or the placed output from this 1st molecular replacement? The second question is about how to relax the restraints fr the packing. In the "other settings" sub window is a section for packing. Could someone explain to me what the different options in this packing section mean? Which of them should I change to allow for more close contacts? Thanks Ursula -- Ursula Schulze-Gahmen, Ph.D. Assistant Researcher UC Berkeley, QB3 356 Stanley Hall #3220 Berkeley, CA 94720-3220

Re: [phenixbb] Unable to install phenix 1.8.1-1168 on Scientific Linux 6.3 64 bits
by Engin Ozkan 29 Jan '13

I just installed yesterday the latest nightly build on our Scientific Linux 6 (6.3, I believe) machine using the 64-bit FC3 installer. No problems.

In most cases the fc3 build is preferred, but there are some newer distributions where an installer built on a more recent version of Fedora is preferable. I would start with fc8 and work your way up.

To be honest I simply don't understand library versioning issues - the Fedora 3 machine we build that installer on currently has glibc 2.3, so I don't know where the GLIBC_2.14 is coming from. I think it will be significantly more work to figure out a workaround than trying the other installers, though. Unfortunately we do not actually have a Scientific Linux system here - the closest I could find was CentOS 6.2, and that works okay. -Nat _______________________________________________ phenixbb mailing list phenixbb(a)phenix-online.org http://phenix-online.org/mailman/listinfo/phenixbb
