Beamline Scheduling Software (BSS) has been developed for the schedule management and equipment control of the RIKEN Structural Genomics Beamlines I and II (BL26B1 and BL26B2 at SPring-8). The beamline operation is automated with a sample-changer robot and a database system. The experimental schedule is registered to BSS as a list of diffraction measurements for numbers of protein crystals. BSS implements the beamline operation communicating with beamline instruments through the computer network. The RIKEN Structural Genomics Beamline I (BL26B1) opened for users using BSS in October 2002, and the automatic operation was implemented at BL26B2 in October 2003.
