Re: [phenixbb] autobuild : change reflection file mid-job?

Hi Bryan, Yes, I think to change the reflections file you will have to rerun the job as the reflections are read once in autobuild and propagated from there out.

[it was inevitable..] if i swap the reflection file mid-job - THAT sounds like catastrophe : so does autobuild determine the format *only* from the .sca, .mtz affix? and it looks like reflections are read once at startup, and propagated from there out? -bryan

Re: [phenixbb] autobuild : change .seq mid-job?
by Thomas C. Terwilliger 13 Sep '10

Hi Bryan, I think that you can do this, though I have not tried it. You need to replace two files: 1. your original sequence file wherever it is "/wherever/.../myseq.dat 2 a file with the same name "myseq.dat" or whatever, in the directory AutoBuild_run_1_/TEMP0 I would expect all model-building after that to have the new sequence. (Note that runs that are already going as sub-processes will keep their sequences). Now if this is rebuild_in_place, this would not be a good idea. I am assuming it is rebuild_in_place=False, and so it should work... Let me know how it turns out, -Tom T >> i have a long autobuild job going. i'd like to change the .seq files as >> its going - if i keep residue 1 numbered, could this still be a >> catastrophe? >> >> -bryan >> _______________________________________________ >> phenixbb mailing list >> phenixbb(a)phenix-online.org >> http://phenix-online.org/mailman/listinfo/phenixbb >>

debugger pdb
by Krista Joosten 10 Sep '10

10 Sep '10

Hi all, I'm working with Tom Burnley on the development of time_averaging.py. I would like to use the debugger pdb, but am not sure how to do this and whether it's possible. After some googling, I tried to hack into phenix.time_averaging adding -m pdb when the variable DEBUG==1, but I got the error message 'no module called pdb'. Bye Krista

Beamtime at the ALS-BCSB beamlines
by Peter Zwart 09 Sep '10

09 Sep '10

Dear All, July 15, 2010 is the deadline for the March/April 2010 Rapid Access Proposal cycle. All Berkeley Center for Structural Biology(BCSB) beamlines are equipped with ADSC Q315/Q315R detectors, automated sample changers and data collection software enabling high-throughput crystal screening and data collection. Remote data collection is available on all BCSB beamlines, providing the user with the full complement of sample visualization, sample manipulation, beamline control, data acquisition and data analysis tools exactly as they would see them if they were stationed at the beamline. The main difference between local operation and remote operation, is the length of the network cable! This enhanced remote operation capability is coupled with 22hr onsite support by BCSB staff who are able to assist immediately with loading additional samples for remote users or troubleshoot any issues that might arise. Remote users can furthermore be kept up-to-date on changes in ring status via an SMS service ( http://bcsb.als.lbl.gov/wiki/index.php/Ring_Status_Notifications_to_Cell_Ph…) or via twitter (@AlsRingStatus). Specific features are summarized below. Beamlines 5.0.1, 5.0.2, 5.0.3: -------------------------------------- Beamline 5.0.2 is equipped with a novel variable collimator allowing users to adjust the beamsize continuously and on the fly between 25 and 100 micron, both horizontally and vertically. With a collimator setting of 30x30 micron, typical exposures are around 1 to 2 second. The Berkeley Automounter sample handling system has a routine capacity of 96 samples (6 pucks). In a typical high-throughput screening mode, the mount-to-mount time is around 2.5 minutes per sample, allowing users to screen a full puck within 45 minutes. The sector 5 beamline user stations are equipped with fully high-adjustable, ergonomically friendly work stations. Beamlines 8.2.1 and 8.2.2: ----------------------------------- To facilitate studies on small crystals, a microdiffractometer was installed in the beamline 8.2.1 endstation. The new equipment allows precise sample positioning to within 2 microns, excellent sample viewing of very small crystals, and an off-axis crystal positioningstage. Both beamlines 8.2.1 and 8.2.2 feature a Rigaku sample changer (Actor), allowing remote operations to now be a routine mode of access for these beamlines. Data analyses in the BCSB is facilitated by software maintained by sbgrid ( http://www.sbgrid.org). A 16 core linux machine is available for our users to process their data and solve/refine their structure. An additional mode of access to the BCSB beamlines is through the Collaborative Crystallography (CC) Program. Users apply for beamtime via the general user program, and collaborate with an expert crystallographer who will conduct the experiments and data reduction on behalf of the researchers. Depending on the users, structure solution, model building and refinement can be carried out as well. Please contact BCSBBeamtime(a)lbl.govfor more information. Please visit http://bcsb.lbl.gov/ for more details about the Center and its beamlines. 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/ Scroll down to "Structural Biology beamines (includes protein SAXS)." Click on "New Proposal." 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.

Help on multi-start-simulated-annealing sigmaA-weighted 2fofc map
by fn1＠rice.edu 09 Sep '10

09 Sep '10

Hi everyone, I read on the paper that they use CNS (model_map.inp) to calculate the avarage sigmaA-weighted 2fofc map. Right now I have set up the simulated annealing with different random seeds. I wonder whether phenix could calculate the average map with the multiple coordinates from different starts? Thanks! Fengyun

Hi, For the pdb file generated by refmac which contains only the residual-B, will phenix.fmodel automatically generates and takes into account the TLS B by reading the TLS REMARK from pdb? Thanks a lot! Best Regards, Hailiang
