You can access the Trait Ontology Browser in any of the following ways:

  • From the toolbar select Tools and Settings > Trait Ontology Browser Icon Trait Ontology Browser. (See Tools and Settings for more information.)
  • From the QTL Browser click a trait in the Trait panel. (See QTLs Tab for more information.)

Trait Ontology Browser Window

The Trait Ontology Browser is organized into several panels, which are described below.

Click the Close button to exit the Trait Ontology Browser.

Trait Hierarchy and Colors

If the trait record in the database has a value for the R (red), G (green), and B (blue) columns then those color components are used for the tree node. If the parent of the tree node has a color then the parent's color is also used. If these conditions are not met then the color white is used.

Please note traits can have multiple parents so it is possible that the same trait could have different colors depending on where it is in the tree. (The Details panel will reflect this.) If a trait does not have a defined color and its parent does not have a defined color but the grandfather trait has a color then the grandfather's color will be used for the father and child nodes.

Trait Hierarchy Panel

The Trait Hierarchy Panel is located on the left side of the Trait Ontology Browser window and shows the hierarchy of the current trait. You can use it to quickly navigate between parent and child traits.

For traits with child traits use the arrows to open and close the hierarchy tree.
