 After the file loads in the Genome Browser, you should see a number of interactions, all arching
 as hills instead of valleys, with some curved and many rectangular indicating a connector to a region
 outside of the browser window. Press the 10x zoom out button to see the full connections.

 <h6>Example #4</h6>
 <p>
 In this example, you will use an example BED file to create a bigInteract file,
 allowing the data to be remotely accessed and exist within a track hub.  The track settings for 
 bigInteract on a hub can be viewed <a href="./trackDb/trackDbHub.html#bigInteract">here</a>.

 data denotes an interaction to another chromosome, chr20, and thus is not represented by an arc.</p>

 <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>
+<a href="http://hgdownload.gi.ucsc.edu/admin/exe/">binary utilities directory</a>.</p>
 <ul>
   <li>
   <code>bigBedToBed</code> &mdash; converts a bigBed file to ASCII BED format.</li>
   <li>
   <code>bigBedSummary</code> &mdash; extracts summary information from a bigBed file.</li>
   <li>
   <code>bigBedInfo</code> &mdash; prints out information about a bigBed file. Use the -as option to see the file field descriptions.</li>
 </ul>
 <p>
 As with all UCSC Genome Browser programs, one can type the program name (with no parameters) at the
 command line to view the usage statement.</p>
 
 <h2>Troubleshooting</h2>
 <p>
 If you encounter an error when you run the <code>bedToBigBed</code> program, check your input 
 file for data coordinates that extend past the end of the chromosome. If these are present, run 
 the <code>bedClip</code> program
