PLINK is a popular and well-documented tool for the association and population-based linkage analyses for genome-wide association studies (GWAS). PLINK is typically used as a command-line tool. In this article, we will show you how to install PLINK 1.90 on a Linux Virtual Machine in the Aridhia DRE Workspace.
Installing PLINK on a Linux VM
1. Download PLINK to your local machine.
From your web browser, go to the PLINK Releases page and download the latest stable Linux 64 bit release.
2. Upload PLINK to the Workspace

uploads folder and unzip PLINK:
cd /files/uploads sudo unzip plink_linux_x86_64_20200616.zip -d plink_install
4. Make PLINK accessible from the command line
To make PLINK accessible from the command line anywhere in the file system, we need to copy the PLINK executable to the

cd plink_install sudo cp plink /usr/local/bin sudo chmod 755 /usr/local/bin/plink
Next, you need to add PLINK to PATH. To do this, run:
sudo nano ~/.bashrc
This will open the nano editor in the terminal. Scroll down to the bottom of the file and add the following line:
Click Ctrl+S and Ctrl+X to save and exit the file.
