Applications are now open for the 2022 edition of RapiData at SSRL - please visit https://www-ssrl.slac.stanford.edu/rapidata/rapidata-2022/ for the most up-to-date information. The workshop will run be virtually via Zoom in much the same way as the 2021 course. RapiData is a practical course in macromolecular X-ray diffraction data collection, data processing and structure solution. The aim of the RapiData course is to educate and train young scientists in data collection and processing methods at synchrotron beamlines, using state-of-the-art software and instrumentation. The course will be run out of the Stanford Synchrotron Radiation Lightsource (SSRL) on the SLAC National Accelerator Laboratory campus from Wednesday May 4 2021 to Saturday May 14 2022, typically starting at 8am PST each day. The weekend of May 7-8 will be free. The course will comprise remote access data collection experiments at the SSRL beamlines, software tutorials, and lectures on the following topics: Specimen preparation, Data collection strategies, X-ray light sources, X-ray detectors, Data reduction, Structure solution by MAD, SAD and Molecular Replacement, Serial Crystallography, and Complementary methods (cryoEM, spectroscopy and small angle scattering). Students may send a limited number of their own crystals for diffraction data collection but this is not a requirement. Please email us and let us know if you are thinking of sending samples. Please go to https://www-ssrl.slac.stanford.edu/rapidata/rapidata-2022/ and use the links on the "Application/Registration" page to apply for the course. The application deadline is January 24 2022. Successful applicants will be notified shortly thereafter, and invited to register. There is no registration fee for this workshop.
