DESeq2(R) Analysis environment setup


With OmicSoft Suite v11.3, you can run the R implementation of DEseq2 directly from OmicSoft Studio, right from the OmicSoft Studio GUI. Because of significant improvements of DEseq2 over the past several years, OmicSoft recommends using the R implementation instead of the native OmicSoft Suite implementation of DEseq2.

This page describes the steps to install and configure R and DEseq2 for execution by OmicSoft Suite.

Installing dependencies

To run DEseq2(R), you will need to install DEseq2 in the appropriate environment; if properly installed, OmicSoft Suite will be able to call your R installation to automatically submit your data for analysis and import full results into your OmicSoft Studio project.

1. Install the R environment on your local computer or OmicSoft Server; R version 4.0 is strongly recommended for DEseq2

2. Install the Bioconductor version compatible with your R version

3. Install the DEseq2 package

Windows Installation: R 4.0.4

Not required if you will run DEseq2 remotely on your Linux-based OmicSoft Server.

Required if you plan to run DEseq2 on your local Windows machine, or are running OmicSoft Server on a Windows Server.

Download R from and follow the executor's steps.

Then be sure to update OmicSoft Studio's SetLocalRScriptEngine.pdf.
