OntoCOG

The NCBI Clusters of Orthologous Groups (COG) system uses evolutionary relationships to cluster proteins from different genomes into different functional categories. OntoCOG is an ontology-based Semantic Web application for COG-based gene set enrichment analysis.

Simple tutorial:

Here is the program:

(1) Select one species
(2) Input protein GIs: Example 1, Example 2 (Protein Virulence factor)
