MetaboAnalystR 3.0 contains the R functions and libraries underlying the popular MetaboAnalyst web server, including metabolomic data analysis, visualization, and functional interpretation. The package is synchronized with the MetaboAnalyst web server. After installing and loading the package, users will be able to reproduce the same results from their local computers using the corresponding R command history downloaded from MetaboAnalyst web site, thereby achieving maximum flexibility and reproducibility.
The version 3.0 aims to improve the current global metabolomics workflow by implementing a fast parameter optimization algorithm for peak picking, and automated identification of the most suitable method for batch effect correction from 12 well-established approaches. In addition, more support for functional interpretation directly from m/z peaks via mummichog2 (PMID: 23861661), and a new pathway-based method to integrate multi'omics data has been added. To demonstrate this new functionality, we provide the "MetaboAnalystR 3.0 Workflow: Towards an Optimized Workflow for Global Metabolomics" vignette, available here as a PDF. In this vignette, we perform end-to-end metabolomics data analysis on the full batch of clinical IBD samples.
To use MetaboAnalystR 3.0, first install all package dependencies. Ensure that you have necessary system environment configured.
For Linux (e.g. Ubuntu 18.04/20.04): libcairo2-dev, libnetcdf-dev, libxml2, libxt-dev and libssl-dev should be installed at frist;
For Windows (e.g. 7/8/8.1/10): Rtools should be installed.
For Mac OS: In order to compile R for Mac OS, you need Xcode and GNU Fortran compiler installed. We suggest you follow these steps to help with your installation.
R base with version > 3.6.1 is recommended. The compatibility of latest version (v4.0.0) is under evaluation. As for installation of package dependencies, there are two options:
Option 1
Enter the R function (metanr_packages) and then use the function. A printed message will appear informing you whether or not any R packages were installed.
Function to download packages:
metanr_packages <- function(){
metr_pkgs <- c("impute", "pcaMethods", "globaltest", "GlobalAncova", "Rgraphviz", "preprocessCore", "genefilter", "sva", "limma", "KEGGgraph", "siggenes","BiocParallel", "MSnbase", "multtest","RBGL","edgeR","fgsea","devtools","crmn","httr","qs")
list_installed <- installed.packages()
new_pkgs <- subset(metr_pkgs, !(metr_pkgs %in% list_installed[, "Package"]))
if(length(new_pkgs)!=0){
if (!requireNamespace("BiocManager", quietly = TRUE))
install.packages("BiocManager")
BiocManager::install(new_pkgs)
print(c(new_pkgs, " packages added..."))
}
if((length(new_pkgs)<1)){
print("No new packages added...")
}
}Usage of function:
metanr_packages()Option 2
Use the pacman R package (for those with >R 3.5.1).
install.packages("pacman")
library(pacman)
pacman::p_load(c("impute", "pcaMethods", "globaltest", "GlobalAncova", "Rgraphviz", "preprocessCore", "genefilter", "sva", "limma", "KEGGgraph", "siggenes","BiocParallel", "MSnbase", "multtest","RBGL","edgeR","fgsea","httr","qs"))MetaboAnalystR 3.0 is freely available from GitHub. The package documentation, including the vignettes for each module and user manual is available within the downloaded R package file. You can install the MetaboAnalylstR 3.0 via any of the three options: A) using the R package devtools, B) cloning the github, C) manually downloading the .tar.gz file. Note that the MetaboAnalystR 3.0 github will have the most up-to-date version of the package.
Due to issues with Latex, some users may find that they are only able to install MetaboAnalystR 3.0 without any documentation (i.e. vignettes).
# Step 1: Install devtools
install.packages("devtools")
library(devtools)
# Step 2: Install MetaboAnalystR with documentation
devtools::install_github("xia-lab/MetaboAnalystR", build = TRUE, build_vignettes = TRUE, build_manual =T)
# Step 2: Install MetaboAnalystR without documentation
devtools::install_github("xia-lab/MetaboAnalystR", build = TRUE, build_vignettes = FALSE)
The * must be replaced by what is actually downloaded and built.
git clone https://github.com/xia-lab/MetaboAnalystR.git
R CMD build MetaboAnalystR
R CMD INSTALL MetaboAnalystR_3.0.3.tar.gz
Manually download the .tar.gz file from here.
cd ~/Downloads
R CMD INSTALL MetaboAnalystR_3.0.3.tar.gz
The case studies have been preformed in our article of this version here (available online now). The example running R code of this article have been provided as a vignette inside the R package.
The R scripts to perform all of the analysis from our previous manuscript "MetaboAnalystR 2.0: From Raw Spectra to Biological Insights" can be found here.
The detailed tutorial of the outdated version to perform a comprehensive end-to-end metabolomics data workflow from raw data preprocessing to knowledge-based analysis still works. The tutorial is available as a PDF is also available inside the R package as a vignette.
To demonstrate the functionality, flexibility, and scalability of the MetaboAnalystR v1.0.0 package, three use-cases using two sets of metabolomics data is available here. In this folder you will find detailed discussions and comparisons with the MetaboAnalyst web-platform.
For detailed tutorials on how to use MetaboAnalystR 3.0, please refer to the R package vignettes. These vignettes include detailed step-by-step workflows with example data for each of the main MetaboAnalytR 3.0 modules, a case-study showcasing the new end-to-end functionality of MetaboAnalystR 3.0. The raw data processing workflow has been accelerated and gradually mature. Note, the functions below work only if the R package vignettes were built.
