SHAMAN is a shiny application for differential analysis of metagenomic data (16S, 18S, 23S, 28S, ITS and WGS) including bioinformatics treatment of raw reads for targeted metagenomics, statistical analysis and results visualization with a large variety of plots (barplot, boxplot, heatmap, …).
The bioinformatics treatment is based on Vsearch [Rognes 2016] which showed to be both accurate and fast [Wescott 2015].The statistical analysis is based on DESeq2 R package [Anders and Huber 2010] which robustly identifies the differential abundant features as suggested in [McMurdie and Holmes 2014] and [Jonsson2016].
SHAMAN robustly identifies the differential abundant genera with the Generalized Linear Model implemented in DESeq2 [Love 2014].
SHAMAN is compatible with standard formats for metagenomic analysis (.csv, .tsv, .biom) and figures can be downloaded in several formats.
A presentation about SHAMAN is available here and a poster here.
Hereafter is the global workflow of the SHAMAN application:
SHAMAN is available for R 3.6.2. Here are different ways to install the application:
Docker install is the easiest way to use SHAMAN locally. First, install docker:
- Install docker on ubuntu (Linux): https://docs.docker.com/engine/installation/linux/ubuntulinux/
- Install docker on Windows and Mac: https://www.docker.com/
Now in your terminal:
docker pull aghozlane/shaman && docker run --rm -p 80:80 -p 5438:5438 aghozlane/shaman
Then connect to http://localhost/ or http://0.0.0.0/ with your favorite web navigator. Failed: port is already allocated ?
docker run --rm -p 3838:80 -p 5438:5438 aghozlane/shaman
Then connect to http://localhost:3838/ or http://0.0.0.0:3838/. Docker update after an update of SHAMAN:
docker pull aghozlane/shaman
SHAMAN is available for R=3.6.2. Packrat framework allows an easy installation of all the dependencies. Of note, raw data submission is not possible with this version.
# Download packrat package
wget https://zenodo.org/record/7418309/files/shaman_package_202204.tar.gz
mkdir packrat/
Now you can run R:
install.packages("renv")
renv::restore(project="./")
system("Rscript -e 'shiny::runGitHub("pierreLec/KronaRShy",port=5438)'",wait=FALSE),
shiny::runGitHub('aghozlane/shaman')
R install will require Gfortran on mac (https://cran.r-project.org/bin/macosx/tools/) and Rtools on windows (https://cran.r-project.org/bin/windows/Rtools/index.html). Of note, raw data submission is not possible with this version.The installation, download and execution can all be performed with a small R script :
# Load shiny packages
if(!require('shiny')){
install.packages('shiny')
library(shiny)
}
# Install dependencies, download last version of SHAMAN from github and run shaman in one command :
runGitHub('aghozlane/shaman')
This script can also be executed as following :
chmod +x ./shaman/www/shaman.R && Rscript ./shaman/www/shaman.R
Conda installation of SHAMAN is available for linux and mac. It can be performed as follow:
# Download and install SHAMAN
conda install -c aghozlane shaman
# Now run shaman
shaman_conda.R
Then connect to http://localhost/ or http://0.0.0.0/.
