IGV supports zooming and scrolling from full genome to base pair resolution. As an example, the tutorial explores chromosome 7:
- 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 between 53,000,000 and 54,000,000, but the resolution is too coarse for the gene names at the left to be readable.

- 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):

- To see the track names, hover over a track. Alternatively, select Tracks>Set Track Height and increase the track size until the track names in the left-most window are legible.
