Percent of residues built for 44 datasets using 3 different processing strategiesPercent of residues built by ARP/wARP using 3 different processing strategies Using REFMAC without phase restrain is statistically significant better (Paired t-Test p<0.01) Best model for different wavelength combinations of 3 wavelength MAD datasets Two different data collection strategies for 3 wavelength MAD. New workflow for Crystallographer Instead of trying to find the structure solution with an iterative approach, 1.) Provide one time all fundamental information about the data collection 2.) Run all possible processing strategies in parallel without any human intervention 3.) Evaluate the results to determine the best solution Conclusion Percent of residues built for 44 datasets using 12 different processing strategies Xsolve is already a valuable component of the JCSG high-throughput structure determination pipeline. Xsolve supports a non-iterative workflow for crystallographers by trying all possible solutions in parallel. None of the processing strategies outperforms the others for all datasets. However they are often complementing each other and Xsolve can maximize the number of automatically built residues by running several processing strategies in parallel. Xsolve is open for extensions with additional crystallography programs. The first Xsolve version for public release will be available in November 2005. Xsolve will be available for some of the SSRL users outside of JCSG with the start of the next run at SSRL in November 2005. Xsolve Processing Steps Create working directory (e.g. resolve/p3221/nmol1/lambda12 ) Assemble input.xml files (e.g. from target.xml, scale.xml, solve.xml) Copy input files to work directory (e.g. solve.mtz, ha.pdb) XSLT to create shell script (e.g. input_resolve.xml -> resolve.csh) Execute shell script (e.g. resolve.csh) Monitor execution (error messages, timeout, file size limits,…) Parse log file (e.g. resolve.log -> resolve.xml) CollectData.xml Trace.xml
