Changing the foreground color changes the color of annotations within a track and the font color of the track label. Changing the track label color changes the color of the track label only.
To change color and font settings
Stack height is the number of annotations that can appear stacked in individual rows within a track. If a location in the genome contains more annotations than can be stacked in their own rows, IGB places them in a summary row. Annotations in the summary row are darker than annotations stacked in individual rows.
Change the stack height setting to change the number of annotations that can be stacked into individual rows.
To change stack height so that every annotation in the current view appears in its own row and no annotations are shown in the summary row
To change stack Height to a specific value
Beginning in IBG 7.0, you can specify the absolute height (in pixels) for one or more tracks. To specifiy the height of a track
To change the track height, Lock Track Height option must be selected.
Use the Label Field menu to specify which annotation property IGB display next to each annotation in a track.
To find out what properties are available to use as annotation labels
A window will open listing annotation properties in the left column and their values in the right column.
To use a property's value as the annotation label in an annotation track
Use the Strand checkboxes to determine how strand will be indicated in a track. You can choose any combination of options in the Strand sub-panel.
Available options for indicating strand include the following:
