Workshop Description

This workshop demonstrates how to leverage public multi-omics databases, such as the cBioPortal and The Cancer Genome Atlas (TCGA). Workshop participants are given an overview of the cBioPortalData, curatedTCGAData, terraTCGAdata, and SingleCellMultiModal, data packages. It introduces users to minimal data management with MultiAssayExperiment and TCGAutils, packages that organize and manage multi-omics datasets. The workshop will provide participants with ways to improve the ease-of-use of TCGA data, and introduce them to common Bioconductor data classes including SummarizedExperiment, MultiAssayExperiment, and RaggedExperiment. The workshop will also demonstrate the experimental terraTCGAdata package for working with TCGA data on the AnVIL Terra platform, as well as, a review of updates to existing functionality in cBioPortalData, MultiAssayExperiment, TCGAutils, TENxIO, and SingleCellMultiModal.

Keywords: Data Representation, Infrastructure, cBioPortal, MultiOmic Integration


  • Basic knowledge of R syntax
  • Familiarity with the GRanges and SummarizedExperiment classes
  • Familiarity with ’omics data types including copy number and gene expression

Workshop Participation

Participants will have a chance to build a MultiAssayExperiment object from scratch, and will also work with data and interfaces from the the curatedTCGAData and cBioPortalData packages.
