ChIP-seq Clusters and Digital DNaseI Hypersensitivity Clusters tracks within the ENCODE Integrated Regulation super-track set, providing summary clustered views. ENCODE data hosted in the Browser has now been fully accessioned through the Gene Expressions Omnibus (GEO) repository (21) and cross-linked back to UCSC. We also added the ENCODE Integrative Analysis Data Hub to the Genome Browser public hubs page (http://genome.ucsc.edu/cgi-bin/hgHubConnect) to provide easy, integrated access to AWG data. Together with the Roadmap Epigenomic data track hub (22), the ENCODE data provide a comprehensive look at DNA landmarks across a large number of tissues.
