The server at http://hgdownload.cse.ucsc.edu/ provides bulk downloads of the browser sequence and annotation data, as well as the Genome Browser source code. The source can be used to set up a mirror site (see instructions at http://genome.ucsc.edu/admin/mirror.html) or to install the large collection of browser bioinformatics command-line utilities on a local computer (see a list at http://genomewiki.ucsc.edu/index.php/Kent_source_utilities). Mirrors of the Genome Browser need not host all of the data hosted by UCSC; assemblies and data of interest can be selectively mirrored (see http://genomewiki.ucsc.edu/index.php/Minimal_Browser_Installation). Users may be interested in setting up a mirror site to host confidential data, to display customized browsers and tracks, and for faster data access.
