The Genome Browser serves as the repository for human and mouse genome data that was contributed through September 2012 by the Encyclopedia of DNA Elements (ENCODE) Consortium (8,9). During the transition of the ENCODE Data Coordination Center role to a joint collaboration with Stanford University, the Genome Browser team has continued to add significant new content to the ENCODE data portal (http://encodeproject.org) and publish newly reprocessed ENCODE data sets (10).
