RapiData: a practical course in macromolecular X-ray diffraction data measurement and structure solving at the NSLS.

RapiData provides two days of high-level lectures, then two more of experimental work on several beamlines of the National Synchrotron Light Source, for about 50 students. Students are invited to bring their own research projects for measurement, and about half of them do. The students frequently solve half a dozen structures during the course. Tutorials by the lecturers run throughout the data-collection period. The crystal-preparation laboratory is popular for tutorials and practice, and often there is a beamline available for practice. This article provides details about the organization of the course and tells some of the reasons for its success.
