 <h2>Creating a sharable URL to view specific tracks</h2>
 <h6>How do I create a link to the Genome Browser to share my data?</h6>
 <p> 
 The easiest way to save and share tracks from the URL is by
 <a href="../cgi-bin/hgLogin" TARGET="_blank">logging in</a> to your Genome Browser account and
 creating a <a href="../goldenPath/help/hgSessionHelp.html">saved session</a>.
 Saved sessions are a versatile way to share data that may include native annotations, Custom
 Tracks, Track Hubs, and Assembly Hubs.</p>

 <h2>Setting Track Visibility via URL</h2>
 <h6>How do I create a custom URL to control the visibility of specific tracks?</h6>
 <p>
 You can control the visibility of tracks from the URL with the following parameters, 
 each linked by the "&amp;" sign, similar to position parameters. For more information, please see
-the <a href="../../goldenPath/help/customTrack.html#optParams" target ="_blank">optional URL 
+the <a href="../goldenPath/help/customTrack.html#optParams" target ="_blank">optional URL 
 parameters</a> section of the Custom Tracks User's Guide. Note that <em>italic text</em> indicates
 a user choice, not a working example.</p>
 <ul>
 <li><code>hideTracks=1</code> - hides all tracks</li>
 <li><code><em>trackName</em>=hide|dense|pack|full</code> - sets specified track or subtrack to a
 chosen visibility</li>
 <li><code>textSize=<em>number</em></code> - sets browser text size to a chosen number, default of 
 8 and maximum of 24</li>
 <li><code>ignoreCookie=1</code> - removes pre-existing user settings like track seletion, custom
 tracks, and track hubs</li>
 </ul>
 <p>
 For example, you can use the following command to hide every track (hideTracks=1) and set the knownGene track to 
 the pack visibility (knownGene=pack):</p>
 <p><code><a href="../cgi-bin/hgTracks?db=hg38&hideTracks=1&knownGene=pack">http://genome.ucsc.edu/cgi-bin/hgTracks?db=hg38&hideTracks=1&knownGene=pack</a></code></p>
 
 <p>Composite tracks have additional URL parameters that encode options to hide, select, and 
 display subtracks.</p>
 <ul>
 <li><code><em>trackName</em>_hideKids=1</code> - hides a specific composite track's subtracks</li>
 <li><code><em>trackName</em>_sel=1</code> - selects specific subtrack to be 'checked', allowing
 display</li>
 </ul>
 <p>For example, the following URL hides all tracks (&amp;hideTracks=1), hides a specific composite
 track's default subtracks (&amp;refSeqComposite_hideKids=1), turns on one specific subtrack 
 (&amp;ncbiRefSeqCurated=full), and checks a box to display that subtrack 
 (&amp;ncbiRefSeqCurated_sel=1).

 <h3>Loading Custom Track data with the URL</h3>
 <h6>How do I create a link to my custom track data?</h6>
 <p>
 You can combine the URL visibility settings with the <code>&amp;hgct_customText=</code> parameter using
 a track line you would otherwise put in the <a href="../cgi-bin/hgCustom">custom track 
 input box</a>. The following example shows the <code>hgct_customText</code> parameter accepting
 a bigBed file URL as a custom track:
 </p>

 <p>
 If you want to add more information to the Custom Track, you can do so using the 
 <code>hgct_customText</code> parameter. Since this is a URL, you must use "%20" to encode
 for spaces and "%0A" for a new line character. For example, the following example shows Custom
 Track input pasted in the <a href="../cgi-bin/hgCustom">custom track input box</a> and the 
 equivalent input in the URL:
 
 <pre>browser position chr21:33038946-33039092

 <h2>Linking to gene specific information</h2>
 <h6>How do I link to a specific gene or specific gene description page?</h6>
 <p>
 To jump directly to a gene's position on the Genome Browser, set the position parameter in the
 URL to a gene symbol (e.g., TP53, MTOR, KRAS) and add the parameter
 <code>&amp;singleSearch=knownCanonical</code>. For example, the following link will open the
 Genome Browser for the hg19 human assembly at the position of TP53 on the knownCanonical dataset
 </p>
 <p><code><a href="../cgi-bin/hgTracks?db=hg19&singleSearch=knownCanonical&position=TP53" target="_blank">http://genome.ucsc.edu/cgi-bin/hgTracks?db=hg19&singleSearch=knownCanonical&position=TP53</a></code></p>
