A recent email of Donna Karolchik – the maintainer of my favorite human genome viewer – reports
The UCSC ENCODE browser for the human genome assembly hg18 (NCBI Build 36) is now available. You can access the browser directly at http://genome.ucsc.edu/ENCODE/encode.hg18.html or by clicking the ENCODE link in the sidebar menu on this page, then clicking the Regions (hg18) link in the sidebar menu on the ENCODE portal page. The hg18 ENCODE browser includes 540 data tables in 59 browser tracks that were migrated from the hg17 browser. The hg17 data coordinates were converted to hg18 coordinates using the UCSC liftOver process. To improve the accessibility of the data, related ENCODE tracks have been gathered into new configuration groupings (“super-tracks”) that can be displayed or hidden using a single visiblity control.
