Here we introduce methylR, a complete pipeline for the analysis of both 450K and EPIC Illumina arrays which not only offers data visualization and normalization but also provide additional features such as the annotation of the genomic features resulting from the analysis, pairwise comparisons of DMCs with different graphical representation plus functional and pathway enrichment as downstream analysis, all packed in a minimal, elegant and intuitive graphical user interface which brings the analysis of array DNA methylation data.
-
All required test data except DNA methylation raw files, can be found here
i. testDataFile1 - differentially methylated data file, can be used for gene features, Volcano plot, chromosome map, gene ontology and pathway enrichment analysis modules.
ii. testDataFile2 - normalized beta value data table, can be used for MDS, PCA plots. PCA plot requires additional group data information, 'groupData'.
iii. heatmapMatrix - heatmap matrix test data file added in the testdata directory. -
DNA methylation test data can be found here
We provide Docker container for local use. Please note, the docker container was built on AMD64 OS architecture to get the full functional capabilities of Shiny/R.
- LinuxOS - (AMD64)
- Ubuntu 20.04LTS
- Docker (version 20.10.18)
- web-browser: Firefox (version 105)
- MacOS - (Intel, AMD64 only)
- Monterey (version 12.5.1)
- Docker (version 20.10.17)
- Docker Desktop (version 4.12.0)
- web-browsers:
- Google Chrome (version 106),

PLEASE NOTE: the ARM64 chipset architecture is actually not supported by methylR.
# with docker container
docker run --rm -p 3838:3838 jd21/methylr:latest
Open the web-browser (check above for your OS), and type:
http://localhost:3838
For Singularity container Thanks to WiilieYu (#3), we found a problem on running Singularity/Apptainer container on methylR and using a script from sigularity-shiny, we solved the issue. Please run the commands below for Singularity container (tested with Singularity v3.8.6) -
- To run the Singularity or Apptainer, please use the following commandlines -
# Copy prepare_template.sh to <YOUR_LOCAL_PATH> and run
/bin/bash prepare_template.sh start
The above command run will generate an script on the terminal and command to run on the server,
$ /bin/bash prepare_template.sh start
Generating shiny configuration...
port: 15910 # PLEASE NOTE THIS WILL BE CHANGED IN YOUR COMPUTER
logs: /tmp/shiny-server.ie3djR
base: /srv/shiny-server
run_as: jyotirmoy #<YOUR_USER_NAME>
Server logging will be in /tmp/shiny-server.ie3djR
To run your server:
singularity run --bind /tmp/shiny-server.ie3djR/logs:/var/log/shiny \
--bind /tmp/shiny-server.ie3djR/lib:/var/lib/shiny-server \
--bind shiny-server.conf:/etc/shiny-server/shiny-server.conf <CONTAINER>
---------------------------------------------------------------------------
For custom applications, also add --bind /srv/shiny-server:/srv/shiny-server
To see your applications, open your browser to http://127.0.0.1:15910 or
open a ssh connection from your computer to your cluster.
- Run the following command on your server
singularity run --bind /tmp/shiny-server.ie3djR/logs:/var/log/shiny \
--bind /tmp/shiny-server.ie3djR/lib:/var/lib/shiny-server \
--bind shiny-server.conf:/etc/shiny-server/shiny-server.conf docker://jd21/methylr:latest
- The terminal will prompt likes

Please follow the manual.
Check the manual for more details. You can also find a complete PDF manual here.
MethylR module mythylysis requires a zipped file as the input dataset that contains Illumina IDAT files and a Sample_sheet as CSV format (See details in the manual). To ease the task for the user, we provided a bash script ('createInputZip.sh') to make the input zip file with IDAT and sample_sheet files (See details in the manual).
A test dataset from a previously published result (GSE207426) with RAW IDAT files for Illumina EPIC array can be found at https://sourceforge.net/projects/methylr/. The test dataset contains three samples in each group and the samples collected from solid tissue (will not work for 'Cell type heterogeneity'). More about the dataset can be found on the Methylome analysis for prediction of long and short-term survival in glioblastoma patients from the Nordic trial (Lysiak, M et al; 2022).
