Saved sessions are a versatile way to share data that may include native data, Custom Tracks, and Track Hubs.</p> <p> You will be able to save and share Genome Browser sessions with the following format: <p><code>http://genome.ucsc.edu/s/<em>userName</em>/<em>sessionName</em></code></p></p> <p> Or if you prefer the a modifiable, longer URL; use this format:</p> <p><code>http://genome.ucsc.edu/cgi-bin/hgTracks?hgS_doOtherUser=submit&hgS_otherUserName=[<em>UserName</em>]&hgS_otherUserSessionName=[<em>SessionName</em>]</code></p> <p> For instructions on creating a saved session, go to the <a href="../goldenPath/help/hgSessionHelp.html#Create">Saved Session Help page</a>.</p> <p> If you want to specify track settings in a URL directly, please read the section on <a href"#trackViz">changing track visibility via URL</a> for a complete description. Note that these URL parameters do not work with the shorter session URLs. <a name="link2"></a> <h2>Linking to the Browser at a specific position</h2> +<h6>How do I make a link to a specific genome or position?</h6> <p> You can link to a specific genome assembly and position in the Genome Browser using a URL with the <code>db=</code> and <code>position=</code> parameters:</p> <p><code>http://genome.ucsc.edu/cgi-bin/hgTracks?db=[<em>db</em>]&position=[<em>position</em>]</code></p> <p> Where:</p> <ul> <li> <code>db</code> - designates a specific genome assembly. For example, <code>db=hg19</code> refers to the Feb. 2009 human genome release. For a list of db parameter values that correspond to UCSC assemblies, see the <a href="FAQreleases.html#release1">list of UCSC releases</a>.</li> <li><code>position</code> - can be any seach term for the genome specified, including a position range or a gene identifier. This often takes the form of <code>position=chr1:35000-40000</code>.</li> </ul> <p>The following link is an example of a URL that declares assembly and position:</p> <p><code><a href=../cgi-bin/hgTracks?db=hg19&position=chr1:35000-40000>http://genome.ucsc.edu/cgi-bin/hgTracks?db=hg19&position=chr1:35000-40000</a></code></p> <a name="hgsid"></a> <h2>The <em>hgsid</em> parameter</h2> +<h6>What is the hgsid parameter and should I include it in Genome Browser links?</h6> <p>The hgsid is a temporary user ID that stores setting and custom track information in the URL. Including it in any shared URLs is a privacy concern, and it should be removed when constructing any links to the Genome Browser. Creating <a href="../goldenPath/help/hgSessionHelp.html#Create">Saved Sessions</a> is the recommended way to share Genome Browser information. </p> <a name="trackViz"></a> <h2>Setting Track Visibitlies 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 "&" sign, similar to position commands. For the full list, please see the <a href="../../goldenPath/help/customTrack.html#optParams" target ="_blank">optional URL parameters</a> section of the Custom Tracks User's Guide.

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> <p> <a name="gene"></a> You can also link directly to gene description pages from the URL. Instead of a position search, gene descriptions use the <code>&hgg_gene=</code> URL parameter. The following URL connecting to 'hgGene' will open up the Genome Browser description page containing protein function, expression profile, and links to additional information for the gene TP53. </p> <p><code><a href="../cgi-bin/hgGene?db=hg19&hgg_gene=TP53" target="_blank">http://genome.ucsc.edu/cgi-bin/hgGene?db=hg19&hgg_gene=TP53</a> </code></p> <h2>Loading data using a URL</h2> <a name="ctUrl"></a> <h3>Load Custom Track data with a 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>&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 is an example of the <code>hgct_customText</code> URL variable, where "%20" is the URL encoding for spaces:</p> <p> Try the following example of the hgct_customText URL variable. <pre><a href=../cgi-bin/hgTracks?db=hg38&hgct_customText=browser%20position=chr1%20track%20type=bigBed%20bigDataUrl=https://genome.ucsc.edu/goldenPath/help/examples/bigBedExample.bb>http://genome.ucsc.edu/cgi-bin/hgTracks?db=hg38&hgct_customText=track%20type=bigBed%20bigDataUrl=https://genome.ucsc.edu/goldenPath/help/examples/bigBedExample.bb</a></pre> </p> <a name="hubUrl"></a> <h3>Load a Track Hub with a URL</h3> +<h6>How do I create a link to my track hub or assembly hub?</h6> <p>Similar to custom tracks, track hubs can be loaded into the URL using the <code>&hubUrl=</code> parameter. This parameter takes input similar to the <a href=../cgi-bin/hgHubConnect#unlistedHubs>track hub interface</a>. Try the following example for reference:</p> <pre><a href=../cgi-bin/hgTracks?hubUrl=https://genome.ucsc.edu/goldenPath/help/examples/hubDirectory/hub.txt&db=hg19>http://genome.ucsc.edu/cgi-bin/hgTracks?hubUrl=https://genome.ucsc.edu/goldenPath/help/examples/hubDirectory/hub.txt&db=hg19</a></pre> <p>Hubs track visibility can also be changed from the URL parameters.
