ONTOLOGY BROWSER AND GVIEWER

RGD uses four hierarchical, controlled vocabularies to annotate genes, QTLs, strains and homologs: Gene Ontology, Mammalian Phenotype Ontology, Disease Ontology and Pathway Ontology. The Ontology Browser allows you to retrieve all genes, QTLs, strains and homologs with similar annotations.

To try the browser, look for terms which contain the word "blood" by selecting "Contains" in the first drop down menu and typing "blood" in the blank box. Select the ontologies to be searched from the second drop down menu. Multiple ontologies can be selected by holding down the shift key. Click on the "GO" button to retrieve a list of terms in the chosen ontologies containing "blood". A click on the desired term will then take you to a list of data objects annotated with the term and its descendants and an interactive graphical image from GViewer.
