GeneXplorer is a web application written by Christian Rees that allows the exploration of large bodies of gene expression data generated by DNA microarray experiments using a web browser as its interface. GeneXplorer is based on the Windows program TreeView written by Michael Eisen. For more information on GeneXplorer, refer to the publication in BMC Bioinformatics (2004) 5:141. The PubMed listing is here.

CaseXplorer is a version of GeneXplorer that has been modified by Chih Long Liu to work with Stainfinder, an on-line program by Wijan Prapong that retrieves the corresponding spot images from an on-line digital image database.

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 SOURCE project at Stanford.
