Data Acquisition and Analysis

The beamline control GUI Blu-ice is installed at all the beamlines. Web-ice provides an interface for diffraction image viewing and automated autoindex and data collection strategy calculation.

Other supported software installed in the alpha servers accessible from all the beamlines include mosflm, HKL2000 and XDS. MAD/SAD scripts, developed at SSRL, are also available to facilitate on-line structure solution. The graphics package COOT is installed on the local beamline computers.
