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", quietly = TRUE))
    install.packages("BiocManager")

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.

Ready-to-use MultiAssayExperiment objects

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

BiocManager::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.

BiocManager::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.
