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.

For information on using the Track Hub features, refer to the Genome Browser Track Hub User Guide. For specific information on configuring your trackDb.txt file, refer to the Track Database Definition Document.

Do Track Hubs require directories for the data?

Track Hubs in a single file

Historically, a hub needed a set of text files to specify properties for a track hub and each of the data tracks within the hub. The track hub settings were stored in a three file structure: hub.txt, genomes.txt, and trackDb.txt

 myHub/          - directory containing track hub files
 * hub.txt       - a short description of hub properties
 * genomes.txt   - list of genome assemblies included in the hub data
 * hg19/         - directory of data for the hg19 (GRCh37) human assembly
 ** trackDb.txt  - display properties for tracks in this directory

Now, there is a trackDb option to have your entire track hub inside of one file, useOneFile on. Adding the useOneFile on line to the hub.txt section of the file allows the contents of all three files to be referenced inside of one file. We recommend the
