Sharing and Managing Lower Level Sequence Data

As TCGA continues to generate massive amounts of data, the size of lower level sequence files has made it necessary for these data to be stored in a larger database. The Cancer Genomics Hub (CGHub) is a secure repository for storing, cataloging and accessing lower levels of sequence data such as sequences and alignments. CGHub is located at University of California Santa Cruz.

Lower level sequence data and metadata are transmitted from the Genome Sequencing Centers (GSCs) and Genome Characterization Centers (GCCs) to CGHub, where they can be accessed by the research community.

All of the TCGA sequence data on CGHub are under Controlled Access, meaning that user certification is required. Metadata are the exception, which are Open Access.
