The DAG Viewer

The DAG Viewer is a plugin that displays all the possible paths to the currently selected term (or terms):

This display shows a view of the ontology where every link that does not end in the selected term has been removed. Hence, every leaf in this tree is the currently selected term.

At the bottom left of the screen is a summary of the number of paths in the trimmed view. A path is a unique collection of links that leads from the selected term to the ontology root. In the example above, there are 5 paths to the root from "virion transport vesicle". Note that even if a term only has one parent, it may have multiple paths to the root if one of its ancestor has multiple parents.

To configure the DAG Viewer, press the "Config" button. A configuration window will appear:

This plugin can be configured via the two checkboxes in the lower right:
