 <h1>Net Format</h1>
 <p>
 The <em>net</em> file format is used to describe the axtNet data that underlie the net alignment 
 annotations in the Genome Browser. For a detailed description of the methods used to generate these 
 data, refer to the Genome Browser description pages that accompany the 
-<a href="http://hgdownload.soe.ucsc.edu/downloads.html">downloadable net alignment tracks</a>.</p>

+target="_blank">example</a> how nets are constructed on our wiki.</p>
 <p>
 At the beginning of each target species chromosome, a &quot;net&quot; line appears with the 
 format:</p> 
 <pre><code>net chromName chromSize</code></pre>
 <p>
 <em>chromName</em> is the target species chromosome name, and <em>chromSize</em> is the
 chromosome size. For example:</p> 
 <pre><code>net chr2L 23011544</code></pre>
 <p>
 Each target chromosome section in the file  starts with a net line. The net line is followed by a 
 set of &quot;fill&quot; and &quot;gap&quot; lines.</p> 
 <p>
 <strong>File indentation:</strong> Line indentation level represents the parent/child relationship 
 between records and is a necessary part of the net file format. Child records are indented one 
 space from the parent, as shown in the example net file below.</p>
