BioC status Platforms Travis Build Status Build status wercker status Coverage Status Downloads


MultiAssayExperiment provides an integrative representation of multi-’omics data on a set of samples. You can choose to represent your data using this infrastructure or use pre-processed datasets from curatedTCGAData.


We recommend installing the stable release version of MultiAssayExperiment in Bioconductor. This can be done using BiocManager:

if (!require("BiocManager"))



Documentation website

The MultiAssayExperiment quick reference, vignettes, and function help pages are available by browsing to the package website.


We provide a reference cheat sheet for a summary of available functionality in MultiAssayExperiment.

Ready-to-use datasets from The Cancer Genome Atlas (TCGA)

For easy-to-use and analysis-ready MultiAssayExperiment objects, use the curatedTCGAData experiment data package:


How to make working with TCGA data easier

TCGAutils is a handy package for working with TCGA data represented as MultiAssayExperiment objects. It is highly recommended to use TCGAutils for TCGA identifier manipulation, sample identification and separation, and much more.

To install TCGAutils, run the following:


Getting help

If you find a bug or error within MultiAssayExperiment, curatedTCGAData, or TCGAutils, please provide a reproducible example in the respective GitHub issues pages: ‘’.
