Track Data Hubs

Track data hubs are collections of external tracks that can be added to the UCSC Genome Browser. Click Connect to attach a hub and redirect to the assembly gateway page. Hub tracks will then show up in the hub's own blue bar track group under the browser graphic. For more information, including where to host your track hub, see our User's Guide.

Track Hubs are created and maintained by external sources. UCSC is not responsible for their content.

Enter hub URLs below to connect hubs. Hubs connected this way are not accessible to other users by default.

If you wish to share your hub you can create a session link. First, connect the hub and configure the tracks image as desired, then navigate to My Sessions (My Data > My Sessions). The resulting stable link can be added to publications and shared freely. You, as the author, also have the power to update the session contents freely. Alternatively, you may build a link with the hub URL to allow users to retain their browser configuration, connected hubs, and custom tracks.

Contact us if you wish to submit a hub to the list of public hubs.

URL:
No connected track or assembly hubs. To connect a hub: Enter its URL into the input box above and click 'Add Hub'. Alternatively, you can go to the 'Public Hubs' tab on this page and connect one of the hubs that were submitted to us. Another way to connect to hubs is via a direct connection link copied using the copy icon, shown on this page, when a hub is connected. You can also connect to hub by following a short link to a saved session, created though the menu 'My Data > My Sessions', if the Genome Browser had connected hubs when the session was saved.

Create your own hub

For information on making track hubs, see the following pages:

You may also contact us if you have any issues or questions on hub development.

Check a hub for errors

Hub URL: Load Example URL

Use the URL bar above to check a hub for errors. This will validate the hub's configuration files, including hub.txt, genomes.txt and trackDb.txt. It will also present a hierarchical tree of tracks with any errors in red. A hub with no errors still shows the tree which can be used to explore the track hierarchy. Hub error checking will always refresh the files and never use our remote file cache (see below).

Enable Genome Browser debugging modes

These apply to all connected hubs. By default, caching is activated and track load times are not shown, but you can change these settings while developing your hub:
