GEPIS (Gene Expression Profiling in silico), is a bioinformatics tool, developed by Dr. Zemin Zhang's group at Genentech, that integrates EST and tissue source information to compute gene expression patterns in a large panel of normal and tumor samples.

We have developed a new application named GeneHub-GEPIS, which will replace this GEPIS program.  GeneHub-GEPIS is built on an integrated gene database that enables extensive cross references for commonly used gene identifiers, thus allowing diverse input values and searching capabilities. The mapping for ESTs to genes is guided by genomic sequences and known gene structure, producing improved expression results. GeneHub-GEPIS will work for both human and mouse genes.
