 <h2>Understanding the interact file format</h2>
 <p>
 This graphic represents the data in <a href="#example2">Example #2</a> with boxes around
 columns of data, separately illustrated as individual custom tracks in the lower image.</p>

 <p>
 The interact file format has <a href="#interact">18 fields</a> where the <b>first 5 fields</b>

 <h2>Sharing your data with others</h2>
 <p>
 If you would like to share your interact/bigInteract 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 bigInteract format</h2>
 <p>
 Because bigInteract files are an extension of bigBed files, which are indexed binary files, it can 
 be difficult to extract data from them. UCSC has developed the following programs to assist
 in working with bigBed formats, available from the 
 <a href="http://hgdownload.soe.ucsc.edu/admin/exe/">binary utilities directory</a>.</p>
