The Broad GDAC standardized data runs aim to produce versioned packages representing a frozen snapshot of all TCGA analysis data at a given time:

  • Cast in a form amenable to immediate algorithmic analysis (no additional data preparation required)
  • Which provides a consistent point of reference for analysis and citation by marker papers and users of TCGA data
  • Towards a formal definition of what constitutes a given tumor dataset
  • While minimizing redundant effort across centers and groups to download & prepare data for further analysis
  • And enhancing provenance and reproducibility

Once mirrored at the DCC, the standardized data packages may be accessed by either clicking on the tumor type links given in the table below (which require DCC protected data credentials) or as described here.  Historical information on this effort is available in this presentation from the April 2011 TCGA meeting, which was refined in subsequent presentations on May 12th and May 19th, as well as the 2011 NCI TSM meeting and ongoing discussions with TCGA collaborators.  Release notes for these runs are available here.
