 After this example bigGenePred track is loaded in the Genome Browser, click on the track to 
 change display from dense to pack, then click on a gene in the Browser's track display to view 
 the gene details page. Note that the page offers links to translated protein, predicted mRNA,
 and genomic sequence.</p>
