missing map coefficients
by Anne Mølgaard 15 Jan '09

15 Jan '09

I am new to Phenix, so there might be an easy explanation for this problem, though I have not been able to find a solution in the documentation. I am using phenix version 1.3b-rc4, intel-linux-2.6. I have solved a structure using phenix.automr, followed by phenix.autobuild (run from command line using "phenix.autobuild data=fromXDS_unique.mtz model=AutoMR_run_2_/MR.1.pdb seq_file=sequence.fas"). The program runs succesfully, and I get the output files I should expect. However, the overall_best_refine_map_coeffs.mtz does not contain the map coefficients 2FOFCWT PH2FOFCWT for the 2mFo-DFc map and FOFC and PHFOFC for the Fo-Fc difference map. mtzdmp gives me the following columns: 1 ASC 0 28 0 100.00 10.6 10.6 28.28 1.85 H H 2 NONE 0 35 0 100.00 13.3 13.3 28.28 1.85 H K 3 NONE 0 71 0 100.00 26.6 26.6 28.28 1.85 H L 4 NONE 1.0 1888.8 0 100.00 148.71 148.71 28.28 1.85 F FP 5 BOTH 1.0 1.0 0 100.00 1.00 1.00 28.28 1.85 Q SIGFP 6 NONE -180.0 180.0 0 100.00 2.08 90.23 28.28 1.85 P PHIM 7 BOTH 1.000 1.000 0 100.00 1.000 1.000 28.28 1.85 W FOMM 8 NONE .0 19.0 0 100.00 9.50 9.50 28.28 1.85 I FreeR_flag 9 BOTH .0 .0 0 100.00 .00 .00 28.28 1.85 F FC What should I do to get these map coefficients?

Hi Nick, I think I tried that at some point, but the problem lies in the IOBS. Some are regular float fortran format: INDE 3 0 0 FOBS= 100.142 SIGMA= 1.478 IOBS= 10028.400 SIGI= 293.800 TEST= 0 while other IOBS are large and for some reason CNS decided to put them in scientific notation such as INDE 5 0 0 FOBS= 492.449 SIGMA= 17.677 IOBS= 0.242506E+06 SIGI= 17098.000 TEST= 0 As far as I can tell this requires two sets of fortran format statements for f2mtz to work properly. format '(6X,3F5.0,6X,F10.3,7X,F10.3,6X,E15.3,/,24X,F10.3,6X,F10.0)' or format '(6X,3F5.0,6X,F10.3,7X,F10.3,6X,F10.3,/,24X,F10.3,6X,F10.0)' I'm playing around with with grep to separate the original cv file into reflections with IOBS in F10.3 format and those with IOBS in E15.3 format, convert with f2mtz, then CAD them together, but this is bloody cumbersome. I was hoping phenix.refine would just automagically figure it all out.

f_prime and f_double_prime in MIRAS/SIRAS
by Leo Sazanov 14 Jan '09

14 Jan '09

Hi, how can one enter f_prime and f_double_prime values for SIRAS/MIRAS experiments in phenix.autosol? Could not find any examples of that in manual, only for MAD. Just putting them in as f_prime=... and f_double_prime=... does not work, it then assumes MAD experiment. Thanks! -- Dr. Leonid A.

Jan 15th deadline - User proposal submission for Collaborative Crystallography at BCSB
by Banumathi Sankaran 13 Jan '09

13 Jan '09

Dear Users, /Deadline for March/April 2009 proposals will be Jan 15, 2009. / Through the Collaborative Crystallography Pilot Program (CC) at the Advanced Light Source, scientists can send protein crystals to Berkeley Center for Structural biology (BCSB) staff researchers for data collection and analysis. The CC Pilot Program can provide an number of benefits to researchers: * Obtain high quality data and analysis through collaborating with expert beamline researchers; * Rapid turn around on projects; * Reduced travel costs. Thumbnail Description: ====================== The Collaborative Crystallography program will be piloted on beamlines 5.0.1 and 5.0.2 for one year; if successful it will be implemented on a permanent basis. CC proposals will go through the regular ALS General User proposal review process for beamtime allocation. Proposals will be reviewed and ranked by the Proposal Study Panel, and beamtime will be allocated accordingly. BCSB staff will schedule the projects to fit into the available resources. Only non-proprietary projects will be accepted. As a condition of participation, BCSB staff researchers who participate in data collection and/or analysis must be appropriately acknowledged - typically being included as authors on publications and in PDB depositions. Please consult the website for additional information at: http://bcsb.als.lbl.gov/wiki/index.php/Collaborative_Crystallography ============= How To Apply: To submit a proposal, go to: http://www-als.lbl.gov/als/quickguide/independinvest.html Click on "protein crystallography" to begin proposal. For question 3 select "Collaborative PX 501/502." For question 9, please describe a specific research project with a clear end point. In order to request CC time for March/April 2009 allocation period, proposals must be submitted by January 15, 2009. The deadline for CC proposals for the time period May/June 2009 will be March 15, 2009. Regards, Banumathi Sankaran

Deadline for ALS PX beamtime this Thursday, Jan 15.
by Peter Zwart 12 Jan '09

12 Jan '09

Dear All, The deadline for general user proposals for PX beamtime at the ALS is coming up soon (Jan 15)! At the BCSB, we have 5 beamlines for which you can apply for beamtime. At the Berkeley Center for Structural Biology (BCSB) we have recently completed a number of upgrades: Sector 8: Recent improvements include: * A high-accuracy microdiffractometer on BL 8.2.1, allowing for centering and viewing of very small crystals * Robotic automounters which can increase the screening throughput at the beamlines, and allows for the implementation of remote data collection. * A new large format (315mm active surface area) CCD detector on BL 8.2.1, facilitating data collection on large unit cell crystals Sector 5: Beamlines (5.0.1 and 5.0.3) now generate 1.5x10^11 photons per second at 0.97 Angstrom. This wavelength is slightly above the Se K edge making them ideal for performing Se SAD experiments. Beamline 5.0.2 (the tunable beamline) generates a peak flux of 8x10^11 photons per second, and the energy range of 5.0.2 has been extended to 17 keV, enabling the routine use of shorter wavelengths and anomalously scattering elements such as bromine. Remote data collection for general users on sector 5 is currently being tested for a limited number of users. Please contact beamline staff for details. Please visit http://bcsb.lbl.gov/ for more details about the Center and its beamlines. If you'd like to apply for next round of beamtime (March-April) at the Advanced Light Source, please submit a General User proposal by Januari 15, 2009. To find out more, click on: http://www-als.lbl.gov/als/quickguide/independinvest.html We invite you to submit a proposal at: http://alsusweb.lbl.gov/4DCGI/WEB_GetForm/PXProposalEntry.shtml/Initialize If you have any questions or would like to request open beamtime, please e-mail BCSBBeamtime(a)lbl.gov. (Please note that executed user agreements must be received by LBNL prior to beamtime. Proprietary fees, if applicable, must be received by LBNL at least five working days prior to scheduled beamtime.) ----------------------------------------------------------------- P.H.

Hi Miles, > Thanks for the info. I see where I can load a parameter file in the > gui (File => Open parameter file) but I don't think I have it with the > right extension (.eff or .param). I'll give it a whirl tomorrow. Oh good, I'm glad to hear that this exists! I'm not sure if it relies on the file extension (it wouldn't be right if it does). I think we should have this option (to load a parameters file) right next to the prompt for PDB, data and CIF files. Best, Pavel.
