GeneXplorer is a web server application that allows the exploration of large bodies of gene expression data generated by DNA microarray experiments using a Web Browser program as it's interface.

The data is displayed in a "Radar" view on the left, and a "Zoom" view on the right. The "Radar" gives an overview of the general patterns observable in the expression data after it has been submitted to a clustering procedure. This clustering process reorders the data by similarity and was recently described by Eisen et al. (1998).

By clicking on a region of interest in the "Radar" view, a regional enlargement will be displayed in the "Zoom" view. Here the names of genes are visible, including links to the Weizman Institute's GeneCards database and the SOURCE project at Stanford.
