Track Hubs

Ensembl provides support for track hubs as a way of sharing large quantities of annotation over the internet. A list of public track hubs is available at the Track Hub Registry based at EMBL-EBI.

You can search this list from the Registry itself, in which case you can use direct links that allow you to attach the Track hub to Ensembl or UCSC. Track hubs on older assemblies may have links to Ensembl archives (for recent releases only).

Alternatively to search for track hubs from within Ensembl, go to Region in Detail, click on 'Custom tracks' and select 'Track Hub Registry Search' from the lefthand menu.

→ See the Track Hub Registry Search for SARS-CoV-2.

If you wish to use a track hub that is not in the Registry, please see our online instructions on how to attach a hub.

Please note that the tracks turned on by default are defined by the Track hub provider so if there are many of these then the hub may be slow to load or unavailable.
