Software for the integration of multi-omics experiments in Bioconductor

https://doi.org/10.1158/0008-5472.CAN-17-0344

Installation

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

if (!require("BiocManager"))
    install.packages("BiocManager")

library(BiocManager)

install("MultiAssayExperiment")

Schematic

Here is a visual overview of the MultiAssayExperiment class. The three main components are:

colData - phenotype data
ExperimentList - a list of tables from experimental results
sampleMap - a graph representation of ‘samples’ and ‘participants’

Note. For simplicity, we use the terms ‘samples’ and ‘participants’ to elucidate the relationship although MultiAssayExperiment can work on other biological specimens.

Cheatsheet

Ready-to-use `MultiAssayExperiment` objects

For easy-to-use and ready-made MultiAssayExperiment objects, use the curatedTCGAData experiment data package.

install("curatedTCGAData")

Companion package for working with TCGA data

TCGAutils is a handy package for working with MultiAssayExperiment data objects from curatedTCGAData. It is highly recommended to use TCGAutils for identifier manipulation, sample identification and more.

install("TCGAutils")

Documentation

The MultiAssayExperiment API is available by browsing to the API wiki.

The `MultiAssayExperiment` Bioconductor Special Interest Group

This group meets remotely to discuss this project approximately every 3 weeks. If you are interested, please join the MultiAssayExperiment Google Group and see the calendar of upcoming meetings.
