Visualization tools for biomedical research

A system of graphical software tools to facilitate the two-dimensional visualization of primary and model data is described. The system uses a direct manipulation interface developed at Duke University Medical Center. This system presents the investigator with different tools to view and manipulate data in various ways and with the ability to cut and paste between display modes. A formal description of the standard self-documenting file structure used by these tools and a description of the display and manipulation tools that make up the system are presented. Examples derived from current use demonstrate how visualization facilitates exploration and analysis by direct manipulation. These concern dose curve response analysis and single channel data analysis. The system make use of the X-window system
