Software
Installation of LigPlot+ on Ubuntu
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.

![[Tutorial] Performing docking using DockingPie plugin in PyMOL.](https://img.bioinformaticsreview.com/uploads/2023/10/25151930/dockingpie1.jpg)
DockingPie [1] is a PyMOL plugin to perform computational docking within PyMOL [2]. In this article, we will perform simple docking using DockingPie1.2.
DockingPie [1] is a plugin of PyMOL [2] made to fulfill the purpose of docking within the PyMOL interface. This plugin will allow you to dock using four different algorithms, namely, Vina, RxDock, SMINA, and ADFR. It will also allow you to perform flexible docking. Though the installation procedure is the same for all OSs, in this article, we are installing this plugin on Ubuntu (Linux).
This is a video tutorial for calculating binding pocket volume using the PyVol plugin [1] in Pymol [2].
If you need to generate the topology of molecules using their SMILES, a simple Python script is available.

How to solve ‘Could NOT find CUDA: Found unsuitable version “10.1”‘ error during GROMACS installation?
Compiling GROMACS [1] with GPU can be trivial. Previously, we have provided a few articles on the same. In this article, we will solve an error frequently occurring during GROMACS installation.
Previously, we installed the Autodock suite [1] on Ubuntu. Visit this article for details. Now, let’s install it on MacOS.
Autodock suite is used for docking small molecules [1]. Recently, Autodock-GPU [2] is developed to accelerate the docking process. Its installation is described in this article. In this tutorial, we will install Autodock 4.2.6 on Ubuntu.
Discovery Studio (DS) Visualizer (from BIOVIA) is a visualization tool for viewing, sharing, and analyzing proteins [1]. Here are some uses and applications of DS Visualizer.
Remote homologs are similar protein structures that share similar functions, but there is no easily detectable sequence similarity in them. A new study has revealed that the protein folding information can be exploited from remote homologous structures. A new tool is developed to recognize such proteins and predict their structure and folding pathway. (more…)
Detecting viruses and bacteria in RNA-seq data with less false positive rate is a difficult task. A new tool is introduced to detect pathogens in RNA-seq data with high precision and recall known as Pathonoia [1].
AlphaFold is a popular artificial intelligence based protein prediction tool [1]. Though it predicts good protein structures, it lacks the capability to predict the small molecules present in the structure such as ligands. For this purpose, AlphaFill is introduced by Hekkelman et al.,[2]. (more…)
Electron density maps are available for most of the protein structures in PDB. Therefore, in this article, we are using PDB to generate electron density maps in Pymol.
PyVOL [1] is an excellent plugin of Pymol [2] for pocket visualization of proteins. In this article, we will install the PyVOL plugin in Pymol on Ubuntu. (more…)
While trying to install Matlab [1], it generally gives an error stating “matlab: command not found.”. Here, we provide a solution to this error.
Kpax is a bioinformatics program to search and align protein structures [1]. It is currently available for Linux platforms only. In this article, we are going to install the latest version of Kpax (5.1.3) on Ubuntu (Linux). (more…)
