Installation of LigPlot+ on Ubuntu

Published

on

LigPlot+ is a bioinformatics software to visually analyze the protein-ligand interactions in 2D [1]. It requires a Java interface to run and can be executed on Ubuntu, Windows, and macOS. In this tutorial, we will install LigPlot+ on Ubuntu. 

Preparing

At first, update and upgrade your system using the following commands:

$ sudo apt-get update
$ sudo apt-get upgrade

Also, Ligplot+ requires the latest version of the Java SE Runtime Environment (JRE) which can be found here.

Downloading Ligplot+

The latest version of LigPlot [2] can be downloaded from here. You have to register yourself first which will be valid for a year. It can be easily downloaded again.

Installing

Open a terminal and change to the directory where you have downloaded the software. Let’s say here it is ‘Downloads’.

$ cd Downloads

$ unzip LigPlus.zip

Executing LigPlot+

Open a terminal and type the following command:

$ java -cp /path/ -jar LigPlus.jar

here /path/ is the path to the directory where the LigPlus.jar file is located.

It will open the LigPlot+.

You can also create an alias.

Open the terminal and type the following commands:

$ sudo gedit ~/.bashrc

It will open the bashrc file, go to the end of the file and add the following command:

alias ligplus='java -cp /path/LigPlus/ -jar /path/LigPlus.jar'

Save the file, go back to the terminal and type:

$ source ~/.bashrc

To start, Ligplot+, type $ ligplus in a terminal.
