How to install IQ-TREE on Ubuntu (Linux)?

IQ-TREE [1] is a bioinformatics software for phylogenetic/phylogenomic inference. It is available as a webserver and a standalone tool. In this article, we are going to install IQ-TREE on Ubuntu.

Preparing system

Open a terminal by pressing Ctrl+Alt+T. Update and upgrade your system using the following commands:

$ sudo apt-get update

$ sudo apt-get upgrade

Downloading IQ-TREE

Let’s change to a directory where you want to download the software. We are downloading in ‘Downloads‘.

$ cd Downloads/

To download the software either visit this page or paste the following commands. We are installing stable version 1.6.12 of IQ-TREE for 64-bit multicore Linux. You can also download for 32-bit.

$ wget https://github.com/Cibiv/IQ-TREE/releases/download/v1.6.12/iqtree-1.6.12-Linux.tar.gz

Installing IQ-TREE

Now extract the downloaded file.

$ tar xvzf iqtree-1.6.12-Linux.tar.gz

A new directory will be created namely, ‘iqtree-1.6.12-Linux‘. Move inside this directory and then to the bin directory.

$ cd iqtree-1.6.12-Linux/bin/

Here you will find an executable file namely, iqtree. Move or copy this file to the /usr/bin/ directory so that you can execute it from anywhere you want.

$ sudo cp iqtree /usr/bin/

Now IQ-TREE can be easily run by typing $ iqtree in the terminal.
