Abstract Summary: The DRAGON View information visualization tools aid in the comprehensive analysis of large-scale gene expression data that has been annotated with biologically relevant information through the generation of three types of complementary graphical outputs. Availability: The DRAGON View tools are freely available on the DRAGON web site at http://pevsnerlab.kennedykrieger.org/dragonview.htm.

UNLABELLED: "Database Referencing of Array Genes ONline" or "DRAGON" is a web-accessible database that aids in the analysis of differential gene expression data as a biological annotation tool. Users of DRAGON can submit data sets containing large lists of genes and then choose particular characteristics that DRAGON supplies for all genes on the list rapidly and simultaneously. AVAILABILITY: The DRAGON database is available for queries on the DRAGON web site www.kennedykrieger.org/pevsnerlab/dragon.htm. CONTACT: [email protected] or [email protected]
