"Applications of Small Angle Scattering to Structural Biology: An

On behalf of the organizing committee, we are pleased to announce a workshop
on "Applications of Small Angle Scattering to Structural Biology: An

This workshop will take place on Friday, July 20th, 2018 at this year's
American Crystallographic Association (ACA) Meeting in Toronto, Canada. The
meeting itself will run from July 20-24.
Over the past two decades, SAS has become a mainstay technique for the study
of structure and composition in solution for structural biologists around
the world. In contrast to the more intensive SAS courses in Europe that
extend across several days, this single-day workshop will be comprised of
carefully constructed lectures and tutorials to serve as an introduction to
investigators new to the technique. The workshop format will include
lectures and a selection of hands-on practical exercises.  Throughout the
workshop the emphasis will be on practical application: knowing how to judge
data quality, how to troubleshoot during data collection, and the
expectations for a successful experiment and acceptable publication.
Students will also learn about aspects of home laboratory data collection
and will be introduced to experiments at national user facilities
(synchrotrons and research reactors).   
Students will be expected to bring laptops with the appropriate
pre-installed software. Extra laptops will be provided in case of unexpected
hardware or software issues on-site, and network connectivity will be
provided as part of the course, as some exercises and tutorials will reply
on external computer-server resources. Preloaded portable disks and memory
sticks will be provided to help reduce the need for large downloads over
conference bandwidth.
We thank Anton-Paar, Rigaku Corporation, SAXSLAB, and Wyatt Technology
Corporation for their kind support of this event.
