Computer-aided designer drug software specialist Polygen Corp, Waltham, Massachusetts, has unveiled the Centrum Technical Information Management System, which it describes as a unified computer-based research automation environment for the chemical and pharmaceutical industries. Built around an intelligent document composer, Centrum provides scientific researchers with access to a series of information management, analysis, modelling, and document composition services designed to help automate the production of typeset-quality technical documents for papers, abstracts, patent applications and correspondence. It supports integration of text, diagrams, experimental data and complex graphical charts from a variety of applications running on heterogeneous computers. Electronic mail facilities are provided, and Centrum includes a set of scientific applications, including chemical structure construction, numerical analysis and equation solving, and access to third-party statistical analysis, chemical structure data base and molecular modelling systems, through hooks and entry points that enable users to incorporate their own applications, to add new ones and to define new information types that can be incorporated into documents. Under Polygen’s agreement with DEC, the Maynarder is providing Polygen with technical consultation and prototypes of its personal graphics workstation line. Centrum runs under both Ultrix and VMS on the new DEC VAXstation 2000 and on other VAXen; it will be available in the second quarter but Poly gen gave no prices for Centrum.
