title: An object oriented user interface for analysis of biological data.
abstract: In a previous paper we described a self-documented file and a collection of general purpose programs or tools that facilitates the management and analysis of biological data. The tools can be specified in a pipeline to accomplish a specific analysis task. However, we found that it was difficult for investigators to learn the UNIX command language for specifying pipelines, specify selection tasks through a command language, and visualize the data as they were transformed and rearranged. To alleviate these problems we developed an object-oriented user interface for the pipeline programs. The system consists of four major programs for visualization: Vedit, Vgraf, Vscan, and V spread. Vedit is a simple text editor, Vgraf is a flexible graphics program, Vscan facilitates scanning graphically through large files, and Vspread provides spreadsheet-like capabilities. To demonstrate how the visualization programs are used together to accomplish the needed analysis we describe two case studies and then discuss how well the system accomplished the goals of visualization, short learning curve, and user adaptability.
