With modern detectors and synchrotron sources, it is now routine to collect complete data sets in 10-30 min. To make the most efficient use of these resources, it is desirable to automate the collection and processing of the diffraction data, ideally to a level at which multiple data sets can be acquired without any intervention. A scheme is described to… (More)
Software engineers at Daresbury Laboratory develop experiment control and data acquisition software to support scientific research. Here, they review their experiences and learning over the years.
OppA is a 58.8 kDa bacterial transport protein involved in the transport of peptides across the cytoplasmic membrane of Gram-negative bacteria. It binds peptides from two to five residues in length but with little sequence specificity. OppA from Salmonella typhimurium has been cloned and expressed in E. coli and the protein cocrystallized with uranyl… (More)
PXGEN is a general-purpose graphical user interface for experimental set-up and control of protein crystallography data collection. PXGEN is not linked intrinsically to any software package or proprietary hardware and should be transportable to other experimental facilities. The experimental techniques supported are single-wavelength data collection and… (More)
Computing provision is of major concern to synchrotron radiation researchers. An overview is presented of the computing facilities for synchrotron radiation work at the Synchrotron Radiation Source, Daresbury Laboratory. Data acquisition, reduction and analysis are seen as an integrated activity essential for full utilization of beam time. We discuss the… (More)
