This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. One of the most widely recognized courses internationally in macromolecular crystallography methods is held at the National Synchrotron Light Source (NSLS). Since 1999, students from around the world have gathered at the NSLS every spring for RapiData, a weeklong crash course organized by Sweet, Alex Soares, and Sal Sclafani, a training component of this P41 project. It's designed to introduce participants to the best and latest equipment and techniques for macromolecular x-ray crystallography. RapiData allows students to meet and learn from the leading developers of software in the crystallography field, and then to actually use NSLS beamlines to collect data. This year, 52 students attended the workshop, which was held from April 19-24. Since its creation, nearly 550 students have attended this course, and we have constant requests to add more slots. Many RapiData alumni have now blossomed into crystallography experts, and they continue to refer their less-experienced colleagues to BNL to learn the initial steps of this highly specialized area of interest. We regularly get graduate students of former RapiData students. The course began with a daylong background session taught by Sweet, meant to refresh the knowledge of crystallography fundamentals for less-experienced students. The following two days were filled with lectures and tutorials taught by scientists from BNL, industry, academia, and other national labs. Next, the students were divided into groups and guided through a marathon, 60-hour data-collection session on six or more NSLS beamlines. At the same time, many tutorials were underway, run by the lecturers themselves. Half of the students brought their own specimens with the goal of solving the structure of a particular enzyme, while the other half observed and helped. About eight structures were solved during the course, each of which could be a publishable result. During the data-collection portion of the course, the students gathered each afternoon to discuss their results and produced mini lectures about their data and scientific subject. It's always really exciting to watch the students'skills develop throughout the week. Many of them come here with little or no experience in crystallography and they leave knowing how to obtain and process real data, as well as how to locate and fix problems as they arise. That's the advantage of having such a hands-on program. In addition to the DOE and NIH funding, a special grant was provided by the Iternational Union for Crystallography to assist six Latin American students in attending the course. Additional support was provided by Brookhaven Science Associates, the NSLS, and several equipment vendors and drug companies.
