Dear Colleagues, We are pleased to announce that registration is now open for the International Conference on Structural Genomics 2011, which will be held in Toronto, Canada on May 10-14, 2011. This meeting is the 6th in this series of biennial meetings of the International Structural Genomics Organization. The meeting is designed to serve as a forum to discuss the most recent developments in structural genomics, structural/chemical biology, and their impact on research in biology, medicine and disease. A substantial number of short talks will be selected from submitted poster abstracts. Also, a limited number of student travel fellowships will be available for travel to this meeting. Please see http://www.icsg2011.org for further details. We hope to see you there!

occupancy refinement
by Dalibor Milic 25 Nov '10

25 Nov '10

Dear all! How to refine occupancies of mutually dependent structural fragments found in alternate conformations, but not consecutive in a sequence? E.g. I want to refine occupancies of two alternate conformations of residues 30 and 451 (see below the corresponding parts of a PDB file). Because of the nature of the structural disorder, an occupancy for altLoc A should be strictly the same in both fragments - the same is valid for altLoc B. Of course, the sum of occupancies for altLoc A and B should add up to 1. Thanks for your suggestions, Dalibor Milic ...

Just an additional comment to my previous e-mail: the refined final value of occupancies in the expression occupancy(AGLU A 30) = occupancy(BGLU A 30) = occupancy(AALA A 451) = occupancy(BALA A 451) were not equal to 0.50 and I got occupancy(AGLU A 30) + occupancy(BGLU A 30) = occupancy(AALA A 451) + occupancy(BALA A 451) < 1.00.

same origin
by r n 24 Nov '10

24 Nov '10

Hi all I wanted to compare the two models from two data set. I want the MR replacement in same origin to compare their them with respect to the map and model. I tried reforigin in ccp4 , it gave me some error , that I am not aware or not clear. I did tried overlay the two model and rfree is going up. Most likely different hands, so Is there any way to compare the two model and data and modify them in Phenix either reindex or shift the model origin to same in all cases. Thought phenix.xmanip could help, not seen any option to do it command line or in the GUI. I did tried def file, but phenix.xmanip params.def , it complains me that unknown file or keyword? any help will be appreciated. Thanks ram

sculptor
by Bryan Lepore 22 Nov '10

22 Nov '10

dev-572 I am checking out sculptor, looks pretty cool, but I provided what i thought was a clustal format alignment to sculptor using --verbose, and it reports "Sorry: Wrong alignment format:" that's it. sounds like user error, but i'm not sure where to proceed next. i tried mafft and clustalw2 output for this. a sample of a bit of the top of the .aln is below. -Bryan p.s: shouldn't readseq convert it to .pir? that'd be code 14 PIR/CODATA?

dev-586 i'll probably try this anyways, but what is the advice on alternate conformations with sculptor? -Bryan

Re: [phenixbb] pid's from output
by Thomas C. Terwilliger 20 Nov '10

Hi Bryan, I added output such as the following to all autosol/autobuild/ligandfit/automr log files: HOST = sigma.lbl.gov HOSTTYPE = x86_64-linux USER = terwill PID = 27371 This will be available starting with tomorrow's PHENIX build. Thanks for suggesting this! -Tom T any way to get pid's of a given phenix process from their output (or any other tricks)? e.g. tried lsof, etc., dug through some title.dat, correlating date.. this would be helpful e.g. when a bunch of autobuilds start after an automr with an expired pid. -Bryan _______________________________________________ phenixbb mailing list phenixbb(a)phenix-online.org http://phenix-online.org/mailman/listinfo/phenixbb

phenix refinement question
by Katarina Moravcevic 20 Nov '10

20 Nov '10

Hi all, I have only started using PHENIX and have made an interesting observation. If I run my model through PHENIX refine (individual sites, individual ADPs, occupancies, optimized X-ray/stereochemistry weight, optimized X-ray/ADP weight options selected) I obtain R/Rfree 0.15/0.18 and very nice geometry values (data is to 1.7A). However, if I now take this refined model and run it through Refmac (without any refinement) I obtain R/Rfree of 0.19/0.21. Can anyone explain why is there such a big difference? Will this be an issue during PDB submission? Any and all comments are appreciated. Thank you all in advance Katarina M.

phenix.elbow with gamess
by William Scott 19 Nov '10

19 Nov '10

The command phenix.elbow --games --smiles="CCO" now fails (1.61 and most recent nightly), but works in an older version of phenix (1.6). Do I need to change input syntax? (I've tried both with older and more recent 32 and 64-bit gamess). Thanks. Bill William G.

any way to get pid's of a given phenix process from their output (or any other tricks)? e.g. tried lsof, etc., dug through some title.dat, correlating date.. this would be helpful e.g. when a bunch of autobuilds start after an automr with an expired pid. -Bryan
