GeneTox manager for bacterial mutagenicity assays: a personal computer and minicomputer system.

GeneTox Manager (GTM) is a data capture, data management, and statistical analysis program used for microbial mutagenicity data. Its main purpose is to provide a homogeneous environment for the collection, organization, and analysis of data generated in the laboratory while also supporting a quality assurance program. The complete system consists of both a personal computer (PC) system and a minicomputer (VAX) system. The joint PC/VAX version of the system is designed to function with both the PC and VAX FOCUS databases so that the VAX can be used for long-term storage, archiving of files, and the analysis of large groups of data. Because of the highly specialized use and nature of the PC/VAX version, this discussion is focused upon the PC stand-alone version. The user-friendly system uses a structured menu system, screen entry helps, and other help screens. GTM provides tabular and graphical summaries of the data and performs specialized statistical analyses. This public domain software was written primarily using Clipper. The manuals and programs are now available through the government's National Technical Information Service.
