The mission of CGHub is to facilitate the work of scientific researchers. CGHub is designed to be a fully automated resource, appearing to users as an extension of their home institute computing resource. User scripts employ the CGHub Application Programming Interface (API) to retrieve the CGHub catalog (index) of files; to select files for download based on metadata attributes such as cancer type, sequence type, source sequencing center or date range; then to initiate download, and finally to confirm success. CGHub is managed by the University of California, Santa Cruz (UCSC), under a subcontract from SAIC-Frederick.
