DETAILS: Managing a flood of data

         Spotfire DecisionSite for Functional Genomics and the Rosetta
         Resolver system are two of the most widely used solutions
         for gene expression analysis in bioresearch and drug
         discovery. Spotfire and Rosetta Biosoftware have integrated
         DecisionSite and Resolver in order to create a powerful,
         complete solution.

         Dr. Rosenberg will present an overview of Biogen's
         information management system for complete support of
         Affymetrix technology and will discuss how Rosetta Resolver
         and Spotfire DecisionSite have been implemented in the
         system. Dr. Rosenberg's presentation will include a
         discussion of the system's:

         --  LIMS for the wet lab;
         --  Quality control process;
         --  Integration engine; and
         --  21 CFR Part 11 compliance.

         Representatives from Spotfire and Rosetta will present:

         --  Additional use cases;
         --  Tips and techniques for exporting expression profiles
             from Resolver to DecisionSite for Functional Genomics;
         --  Recommended methods of visualizing and exploring gene
             expression data in DecisionSite for Functional Genomics;
             and
         --  A near-term road map of enhancements to the integration.
