MotifExpress is a tool for rapidly discovering cis-regulatory motifs by correlating sequence to expression data. It will discover motifs whose presence is best correlated with changes in genome-wide gene expression from a control state to an experimental state. It uses expression data as measured by microarray or RNA-seq, and repeatmasked sequence data from regions relevant to the genes whose expression has been measured.

Installing MotifExpress

MotifExpress was designed for win32 systems, and requires a number of prerequisites to function. You should download them first, if you do not have them:

MotifExpress was developed by Leonid Zamdborg and Ping Ma at the Institute for Genomic Biology, University of Illinois at Urbana-Champaign. It incorporates code written by Erin M. Conlon and X. Shirley Liu (MDScan), Berwin Turlach (SVS), Leonard Richardson (BeautifulSoup), and the Cygwin Project.
