When a project is opened in the default value in the NextGENe Viewer, three options are available for specifying the information that is to be displayed in the Mutation report, including the Variation Tracks Settings dialog box. The Variation Tracks Settings dialog box contains the tracks settings for the Mutation report based on the variation databases that were imported for the project. (After being imported into NextGENe, a variation database is referred to as a track.) Each track for a project has its own unique settings.
