The goal of the Collaboratory for Protein Crystallography at
SSRL is to design and implement “virtual beam lines” within the
framework of “center without walls”, which provides an environment
in which researchers distributed anywhere in the world can access to national
resources for their collaboration on structure molecular biology research.
Under this framework, the local and remote users are both given abilities to
take full advantage of the beam line resources including the beam line control
hardware and software, detectors, computers, and all legacy crystallography
programs. We hope this collaboratory environment will encourage the
collaborations between scientists of multi-disciplines, and result in a wealth
production of new scientific discoveries.
The current features of Collaboratory include the standard
data collection interface, unification of user accounts and home directories
across all beam lines, high performance network infrastructure, massive data
system common to all beam lines. Remote access is currently provided via thin
client technology that gives local and remote users identical computing
environments. A diffraction image viewer accessible via a web browser allows
users to monitor the diffraction images being collected at the real time without
installing any special crystallographic graphical program. Live video is used
within the Collaboratory for the remote crystal monitoring and beam line general
instrumentation viewing to ensure safe remote operation of beam lines. The high
volume, centralized archive system was under development to permanently store
x-ray diffraction images and metadata associated. The archive system will be
located at SDSC, which operates a High-Performance Storage System (HPSS) giving
high-speed access to approximately 1 Petabyte of tape storage.
