  1. MultiFun terms were assigned to annotated concepts associated with genes. A threshold of 30% of documents was considered for ontology assignment and a threshold of 10% was used to point out the genes that most contributed to such assignment.
  2. NA: corresponds to non-annotated gene products in the corpus.
