  Abstract

Many types of genomic data can be represented in matrix format, with rows corresponding to genes and columns corresponding to gene features. The heat map is a popular technique for visualizing such data, plotting the data on a two-dimensional grid and using a color scale to represent the magnitude of each matrix entry. Prism is a web-based software tool for quickly generating annotated heat map visualizations of genome-wide data. The tool provides a selection of genome-specific annotation catalogs, as well as a catalog upload capability. The generated heat maps are clickable, allowing the user to drill down to examine specific matrix entries, and gene annotations are linked to relevant genomic databases.
