goSTAG
Gene Ontology Subtrees to Tag and Annotate Genes within a set
We developed goSTAG for utilizing Gene Ontology Subtrees to Tag and Annotate Genes that are part of a set. Given gene lists, goSTAG performs GO enrichment analysis and clusters the GO terms based on the p-values from the significance tests. GO subtrees are constructed for each cluster, and the term that has the most paths to the root within the subtree is used to tag and annotate the cluster.
