Users are now encouraged to contribute information to the Genome Browser via the Wiki track, available in the Mapping and Sequencing Tracks section on the hg18 and hg19 human browsers and the mm9 mouse browser. The Wiki track contains user-added annotations that are displayed like regular annotations; clicking on an item in the track opens a corresponding page for the gene or region on the Genome Browser wiki site (http://genomewiki.cse.ucsc.edu/), where any user can log in and create or edit pages (9). Wiki track annotations may be added for a specific gene locus in the UCSC Genes track by clicking on a gene and then the ‘User annotations’ link. Alternatively, annotations to any genomic region within a chromosome may be made by clicking on the red ‘Make new entry’ bar at the top of the Wiki track. This interactive mode of adding content to the browser allows researchers to directly annotate genes in their areas of expertise.
