Track hubs can be displayed on genomes that UCSC directly supports, or on your own sequence. Hubs are a useful tool for visualizing a large number of genome-wide data sets. For example, a project -that has produced several wiggle plots of data can use the hub utility to organize the tracks into -composite and super-tracks, making it possible to show the data for a large collection of tissues -and experimental conditions in a visually elegant way, similar to how the ENCODE native data tracks -are displayed in the browser.</p> +that has produced several <a href="wiggle.html" target="_blank">wiggle plots</a> of data can use the +hub utility to organize the tracks into composite and super-tracks, making it possible to show the +data for a large collection of tissues and experimental conditions in a visually elegant way, +similar to how the ENCODE native data tracks are displayed in the browser.</p> <p> The track hub utility allows efficient access to data sets from around the world through the familiar Genome Browser interface. Browser users can display tracks from any public track hub that has been registered with UCSC. Additionally, users can import data from unlisted hubs or can set up, display, and share their own track hubs. Genome assemblies that UCSC does not support can be loaded and viewed with associated data.</p> <p> The data underlying the tracks and optional sequence in a hub reside on the remote server of the data provider rather than at UCSC. Genomic annotations are stored in compressed binary indexed files in bigBed, bigBarChart, bigGenePred, bigNarrowPeak, bigMethyl, bigPsl, bigChain, bigInteract, bigMaf, bigWig, BAM, CRAM, HAL, hic or VCF format that contain the data at several resolutions. In the case of assemblies that UCSC does not support, genomic sequence is stored in the efficient twoBit format. When a hub track is displayed in the Genome Browser, only the relevant data needed to support the view of the current genomic region @@ -185,31 +185,31 @@ <ul> <li><a href="http://genome.ucsc.edu/s/ExampleUser/TrackHubSession"> http://genome.ucsc.edu/s/ExampleUser/TrackHubSession</a></li> </ul> <p>For additional information, see <a href="hgSessionHelp.html#HowToShare">sharing Saved Sessions </a> and <a href="hgSessionHelp.html#Create"> backing up custom data</a>.</p> <a name="hubUrl"></a> <h3>Creating a URL for a Track Hub</h3> <p>Hubs can be loaded into the URL using the <code>hubUrl=</code> parameter.
