This tool returns the results in a pie chart, which displays an overview of all ontology terms at the first (or most general) level within the same ontology (Figure 6). When a slice of the pie chart, which represents an ontology term, is clicked, a new pie chart will appear that contains its child ontology terms. Since one gene can be classified to more than one term, the pie chart is calculated based on the number of “hits” to the terms over the total number of class hits. Class hit means independent ontology terms. For example, if a gene is classified to 2 ontology terms that are not parent or child to each other, it counts as 2 class hits.
