phenix.automr problem
by allbette＠gmail.com 25 Jul '08

25 Jul '08

Dear all I tried to solve a structure by using phenix.automr. I am not sure how many molecules in the asymmetric unit(2-8molecules). How I can tell phenix.automr (phaser) that search at least 2 molecules in asymmetric unit use command line. Any suggestions are welcome.Thank you in advance. carl soja

Re: [phenixbb] autobuild failed

Dear Kaituo, I'm sorry for the problem! I'm not certain what went wrong in this case. It could be that the size of the structure is too big, or it could be a problem with autobuild, or it could be a problem with slow read/write to your file system. The error message "Unable to read ok_file...trying bigger version" will occur if resolve does not finish writing out the file "resolve.ok" immediately after finishing. If you are running on a system that is NFS-mounted, you might try instead running on the local disk. This might fix it. Otherwise, can you help me figure this out by eliminating other possibilities: 1. Can you tell me the version of phenix you are using and what machine this is on: echo $PHENIX_VERSION uname -a 2. Can you send me the entire log file AutoBuild_run_1_1.log 3. Can you send me the file AutoBuild_run_1_/TEMP0/temporary.com 4. If you are willing to send your data, that would be helpful: just tar up your data files and command file and then attach it to an email (but rename the file ".txt" so that it will get sent properly through my email system). Then I can try to reproduce the problem here. All the best, Tom T > My autobuild failed and the log file said: > Columns used: labin FP=F SIGFP=SIGF FreeR_flag=FreeR_flag > Unable to read ok_file...trying bigger version > Failed to run resolve > ---------------------------------- > TRIED resolve ...but not OK > > ********************************************************************************Failed > to carry out AutoBuild_set_up_build: > failure > > how t solve this? > thanks > > kaituo > > peking University, Beijing > _______________________________________________ > phenixbb mailing list > phenixbb(a)phenix-online.org > http://www.phenix-online.org/mailman/listinfo/phenixbb >

Final reminder: 2008 Crystallographic Computing School
by Ralf W. Grosse-Kunstleve 23 Jul '08

23 Jul '08

The registration deadline for the 2008 Crystallographic Computing School is in two days: *** July 25 *** The schedule of the program including abstracts from all speakers is available here: http://www.iucr.org/iucr-top/comm/ccom/kyoto2008/program.html This program puts a strong weight on fostering one-on-one interactions. There will be only 16 lectures of 45 minutes each (12 hours total) but more than 20 hours of tutorials and demonstrations. Don't miss this unique opportunity for close interaction with the developer community! On behalf of the organizing committee: A. L. Spek (Utrecht University , Netherlands) R.

Creating files with positive and negative map peaks
by Jennifer Ekstrom 23 Jul '08

23 Jul '08

I would like to obtain a file with a listing of positive and negative difference map peaks, similar in formatting and content to the files that would come out of cns: positive peaks in: <output_root>_positive.peaks negative peaks in: <output_root>_negative.peaks We need this for use in DDQ at the jcsg validation server (http://www.jcsg.org/prod/scripts/validation/sv2.cgi). Is there an easy way to create these peak files in phenix.refine? We'd prefer to not re-refine in CNS as we have *many* alternate conformations... Thanks, Jennifer

SIR with sites from SAD?
by Francis E Reyes 17 Jul '08

17 Jul '08

I have a SAD dataset where autosol was able to find sites, but the resulting density modified map was uninterpretable. The unit cell for this SAD set was Unit cell: (53.2373, 53.2373, 186.446, 90, 90, 90) . I now have a heavy atom derivative. What's the format of autosol.inp (to be passed to phenix.runWizard AutoSol) that allows me to use the heavy atom sites from the SAD set as a basis for helping find heavy atom sites in the heavy atom derivative? Is it the same as SIR, except use ha_sites_file for the SAD solution? Native unit cell: [53.155600000000007, 53.1556000 00000007, 187.37970000000001, 90.0, 90.0, 90.0 Derivative unit cell: [53.1 82299999999998, 53.182299999999998, 187.59569999999999, 90.0, 90.0, 90.0].

Anomalous difference map calcluation
by Jendrek 16 Jul '08

16 Jul '08

Dear All, I'm looking at my anomalous difference map from phenix.refine and it seems more or less random distributions of electron density peaks. I know that the signal is there since I solved it with SAD. I'm using I(+/-) for refinement and everything seems to work fine except the map generation. The only thing that worries me is that during the creation of _data file for refinement DANO column was not preserved. Is it necessary for phenix.refine in order to generate the anomalous difference map? How can I make sure that the DANO column is preserved (if necessary)? And by the way why is anomalous map file not generated just coefficients in the mtz?
