Sample Attributes

Attributes can be associated with tracks  and used for filtering, sorting, and grouping data.  By default all tracks have at least 3 attributes: Data File, Data Type, and Name. To display additional attributes, load a sample attribute file.  IGV displays attribute names and values in the attributes panel.

Color-Coded Attribute Values

IGV uses color-coded blocks to represent the attribute values.

  • Hover over a colored block to display the attribute value.
  • Click a colored block to select all tracks with that attribute value. IGV indicates a selected track by highlighting the track name.  Tip: Keep in mind that clicking an attribute may select tracks that are not visible in the data panel. Scroll down the data panel to view all the selected tracks.

Showing and Hiding Attributes

To show or hide selected attributes:

  1. Click View>Select Attributes to Show. IGV displays a list of attributes.
  2. Select (or clear) an attribute’s check box to show (or hide) the attribute.
  3. Click OK. IGV updates the display to show only the selected attributes.

To show or hide all attributes:

  • Click View>Show Attribute Display to toggle the setting. A check mark next to the menu item indicates that the attribute panel is displayed. No check mark indicates that it is hidden.
    Tip: This is a persistent setting. Toggling the menu item also toggles the corresponding setting on the General tab of the Preferences window and vice versa.
