In thomazbastiaanssen/anansi: Annotation-Based Analysis of Specific Interactions

Knowledge-based multi-modal integration using anansi

Introduction

The anansi package computes and compares the association between the features of two ’omics data sets that are known to interact based on a database such as KEGG. Studies including both microbiome and metabolomics data are becoming more common. Often, it would be helpful to integrate both data sets in order to see if they corroborate each others patterns. All vs all association is imprecise and likely to yield spurious associations. This package takes a knowledge-based approach to constrain association search space, only considering metabolite-function interactions that have been recorded in a pathway database. This package also provides a framework to assess differential association.

While anansi is geared towards metabolite-function interactions in the context of host-microbe interactions, it is perfectly capable of handling any other pair of data sets where some features interact canonically.

Installation instructions

Get the latest stable R release from CRAN. Then install anansi from Bioconductor using the following code:

if (!requireNamespace("BiocManager", quietly = TRUE)) {
    install.packages("BiocManager")
}

BiocManager::install("anansi")

And the development version from GitHub with remotes:

install.packages("remotes")
remotes::install_github("thomazbastiaanssen/anansi")

Getting started using anansi

See the vignettes on the package site. Additionally, a preprint is available.
