Key features:

• User friendly web-based interface

• Expandable tree for browsing the GO hierarchy, Fixed tree as HTML output for archive, Bar chart for publication

• Statistic analysis indicating GO terms with relatively enriched gene numbers and suggesting biological areas that warrant further study. Sub-tree and DAG visualizing enriched GO categories

• Retrieving subset of genes by GO term or keyword searching.
