hydrogens in low resolution structure refinement
by Stefanie Krieg 17 Nov '07

17 Nov '07

Dear all! I am refining two structures at 3.0 and 2.7 A. In some older threads on this board I found that you recommended adding hydrogens to the pdb file even at this resolution. I tried that (adding hydrogens with reduce and refine with riding hydrogens) but inspite of what I read in your postings, my R-Factors went up by 1% (not down as was predicted). Are there any other keywords which could be changed or do you have any other ideas why this could be? Thanks in advance! Stefanie

Re: [phenixbb] use of wavelength_list=

Hi Bryan, phenix.autosol uses the values in wavelength_list to guess scattering factors if you do not supply values for scattering factors.

does phenix use the 'wavelength_list=' command line flag in calculations? or is it used for no more than data set labeling e.g. derivatives, as solve works? -bryan

Collaborative Crystallography Program - Advanced Light Source
by Paul Adams 09 Nov '07

09 Nov '07

The Berkeley Center for Structural Biology (BCSB) is pleased to announce the launch of a Collaborative Crystallography Pilot Program (CC) at the Advanced Light Source in Berkeley. Through this program, scientists will be able to send protein crystals to 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://alsusweb.lbl.gov/4DCGI/WEB_GetForm/PXProposalEntry.shtml/ Initialize. 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 January/February, 2008, proposals must be submitted by November 15, 2007. -- Paul Adams Deputy Division Director, Physical Biosciences Division, Lawrence Berkeley Lab Adjunct Professor, Department of Bioengineering, U.C.

Re: [phenixbb] phenix.autobuild opinion on sequence file
by Tom Terwilliger 09 Nov '07

09 Nov '07

Hi Bryan, I haven't tried your approach, but my guess would be that the correct sequence file will be the better way to go... The side chains are fitted after building main-chain so the sequence is not going to affect the main-chain build in any direct way (though the sequence will help the wizard in identifying and correcting places where loops are built with the wrong number of residues). -Tom T At 01:32 PM 11/8/2007, you wrote: >i was thinking about giving phenix.autobuild a poly-Ser/Gly,Ala-intact (or >other incomplete variant) _sequence_file_, so it doesn't inter alia put >arginine into strands... though the solvent content will be imprecise.. > >has anyone noticed if such a trick was more/less favorable to the (proper) >complete sequence approach? any pertinent detail or criticisms >appreciated. > >-bryan >_______________________________________________ >phenixbb mailing list >phenixbb(a)phenix-online.org >http://www.phenix-online.org/mailman/listinfo/phenixbb Thomas C.

phenix.autobuild opinion on sequence file
by Bryan W. Lepore 09 Nov '07

09 Nov '07

i was thinking about giving phenix.autobuild a poly-Ser/Gly,Ala-intact (or other incomplete variant) _sequence_file_, so it doesn't inter alia put arginine into strands... though the solvent content will be imprecise.. has anyone noticed if such a trick was more/less favorable to the (proper) complete sequence approach? any pertinent detail or criticisms appreciated. -bryan

problem finding large no of sites in high symmetry
by Banumathi Sankaran 09 Nov '07

09 Nov '07

Hi, I am working with a data set collected in P23 space group. I am expecting 23 Se sites. Hyss gives me warning:run time error for finding large no of site. I did not interupt the run. I waited for 1hr and still it could not find sites. Shelx gave me out of 100 solutions only one had good CC and found 15 sites. IS there a way that this problem can be solved in hyss ? Thanks Banu
