Zoom and Scroll

IGV supports zooming and scrolling from full genome to base pair resolution. As an example, the tutorial explores chromosome 7:

1. Jump to chromosome 7 by clicking 7 at the top of the whole genome view or by selecting chr7 from the drop-down chromosome list in the toolbar. Note that the heat map display of chromosome 7 makes it easy to see the amplifications in bright red between 53,000,000 and 54,000,000.
2. Zoom in by double-clicking on the amplified area of data tracks until you are viewing approximately 21 MB (you can also use the zoom slider in the upper-right corner of the IGV window):
3. To see the track names, hover over a track.
