Overview

The Overview shows an overview of the chromosome currently selected in the Genome view and its features.

To access the view for the first time in a session, select a row in the Chromosomes section and click the Show overview of selected chromosomes tool (). Once the view has been created for a session, you can return to it by clicking on the Overview tab (which uses the same icon as the tool) or using View > Overview > (Name) > Show.

The Overview primarily serves as a way to view a selected chromosome at a different zoom level than is being used in the Analysis view.

The appearance of a ruler and/or features are controlled through “Overview”-related checkboxes in the Tracks panel. See Work with Tracks for more information.

The following table shows tasks associated with the Overview:
