Data Acquisition and Analysis

The beam line control GUI Blu-ice is installed at all the macromolecular crystallography beam lines. Web-ice provides an interface for diffraction image viewing and automated autoindex and data collection strategy calculation.

Other supported software installed on servers accessible from all the beam lines 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 beam line computers.
