 <h2>Sharing your data with others</h2>
 <p>
 If you would like to share your bigWig data track with a colleague, learn how to create a URL by 
 looking at Example #6 on <a href="customTrack.html#EXAMPLE6">this page</a>.</p>

 <h2>Extracting data from the bigWig format</h2>
 <p>
 Because bigWig files are indexed binary files, it can be difficult to extract data from them. 
 UCSC has developed the following programs to assist in working with these files, available from 
 the <a href="http://hgdownload.soe.ucsc.edu/admin/exe/">binary utilities directory</a>.
 <ul>
   <li>
   <code>bigWigToBedGraph</code> &mdash; converts a bigWig file to ASCII 
   <a href="http://genome.ucsc.edu/FAQ/FAQformat.html#format1.8">bedGraph</a> format.</li>
