Figure 7From: OGO: an ontological approach for integrating knowledge about orthologyGraphical representation of an example of mapping rules for Homologene. This resource consists of a single file that contains all the orthology information available. This file consists of six columns: (1) cluster identifier; (2) organism identifier; (3) gene identifier; (4) gene name; (5) protein identifier; and (6) protein name. The mapping rules shown in the figure link each column data to the corresponding concepts in the OGO ontology.Back to article page
