Genome Viewer Upgrades

April 20, 2015

The 2012 tracks have been added to the CHO-K1 JBrowse genome viewer tool. In addition, the 2014 Chinese hamster RefSeq browser has been created with annotation tracks. A new portal page provides access to these browsers by selecting the Genome Viewer tab or button. Also, new links are available in the RefSeq gene details page that link directly to the appropriate JBrowse viewer and scaffold.
