Track hub

A track hub is a structured directory of genomic data, such as gene expression or epigenetic data, viewable over the web with a genome browser. Track hubs are defined by the track hub standard.[1] Originally developed as part of the UCSC genome browser, they are now supported by Ensembl, BioDalliance and JBrowse.

Track hubs are a useful and efficient tool for visualizing large data sets. Collections of wiggle plots produced by a transcriptomics study can be organized hierarchically into so called composite and super-tracks.[2]
