Accessing public data hosted by Google
For each set of Google Genomics public data, you can access data programmatically, interactively or as files.
Programmatic access is available via the Genomics API which implements the Global Alliance for Genomics and Health APIs as demonstrated with numerous open source examples in GitHub, including a sample genome browser.
Go to the genomics-public-data project in BigQuery.
File access is available from Google Cloud Storage. Files are available in BAM, VCF and FASTA formats. Just copy the files you need to local disk on a Compute Engine VM for access from your favorite bioinformatics tools. Use gsutil to access data in the Cloud Storage bucket located at:
For public data hosted by the community on Google, it's up to each data provider as to what modes of access they support.
