get_lowest_common_ancestor.pl - the lowest common ancestor (LCA) of two terms in a given OBO ontology.
Gets the lowest common ancestor (LCA) of two terms in a given OBO-formatted ontology. This script is generally used with taxonomies (e.g. NCBI taxonomy). This version only gets the LCA computed through the 'is_a' relationship type. Also, it assumes that there is only one root term in the ontology.
