Assembly Data Hubs extend the functionality of Track Data Hubs to assemblies that are not hosted
natively on the Browser. Assembly Data Hubs were developed to address the increasing need for
researchers to annotate sequence for which UCSC does not provide an annotation database. They allow
researchers to include the underlying reference sequence, as well as data tracks that annotate that
sequence. Sequence is stored in the UCSC twoBit format, and the annotation tracks are stored in the
-same manner as Track Data Hubs. For more information on how to setup your own Assembly Data Hub,

The Genome Browser provides links to a collection of public track hubs that have been registered with UCSC. To view a list of the public track hubs available, click into the blue navigation bar "My Data" and then "Track Hubs" to reach the Public Track Hubs page. You can click links in the "Description" column to see details about a particular Hub. To view a hub's data, click on an assembly name on the row of your hub or the "Connect" button. If you clicked the "Connect" button, choose your assembly or click the "Genome Browser" link from the top blue bar to be brought to the
