DAVID (Database for Annotation, Visualization and Integrated Discovery) is a public web server that help to identify the pathways biologically relevant to gene data sets. DAVID’s Functional Annotation Tool uses the pathways constructed Kyoto Encyclopedia of Genes and Genomes (KEGG). David is available to the general public and can be accessed at
https://david.ncifcrf.gov/home.jsp. DAVID also has a Functional annotation Tool to perform Gene Ontology analysis. The number of gene in the data set is limited to 3,000. For a larger data set you could use the Generic Gene Ontology Term Finder developed by Princeton University.
