Sort Tracks Based on Region of Interest

In this tutorial, you have sorted and grouped tracks by attribute. In IGV, you can also define a region of interest on the genome and sort tracks based on the data in that region. As an example, define a region of interest around the highly amplified region and sort the tracks based on the data values in that region:

1. Click the Define a region of interest icon in the tool bar.
   
2. Click in the data panel to the left of the bright red area to define the start of the region.
3. Click in the data panel to the right of the bright red area to define the end of the region. IGV draws a red annotation bar above the data panel to indicate the region.
4. Click the red annotation bar for the region. IGV displays a menu.
   
   
5. Select Sort by amplification, which sorts the tracks in each group based on copy number values in this region, from highest to lowest.
