The GBrowse Search Box

   To select a region of the genome to view:

  1. Enter its name in the text field labeled “Landmark or Region”. Recognized types of names/symbols are genes, QTLs, markers, strains, database accession numbers, disease terms, or chromosome number with coordinates.
  2. Click the “Search” button.

Navigation Functions

       Once a region is displayed, you can navigate through it in a number of ways:

  1. Click and drag on a ruler in the “Overview”, “Region” and “Details” panels. Click once to recenter the view at the desired position, or click and drag to select a region.
  2. Scroll left or right with the <<, <, > and >> buttons which appear in the “Scroll/Zoom” section of the screen, and at the top right and left corners of the “Details” panel.  The << and >> buttons scroll an entire screen’s worth, while < and >> scroll a half screen.
3.  Zoom in or out using the sizing selection drop-down menu (“Show # bp”).  The menu item name indicates the number of base pairs to show in the full width of the “Details” panel. For example, selecting the item “100 Kbp” will zoom the “Details” panel so as to show a region 100 Kbp wide.

4.  Make fine adjustments (10-20%) of the zoom level by clicking the “-” and “+” buttons adjacent to the sizing selection drop-down menu.

5.  To flip the browser display so that the sequence coordinates increase from right to left in the “Details” panel, select the “flip” checkbox.
