Network visualization has become a strong need for studying the molecular interactions whether they are the protein or gene interactions. Network information is utilized in many contexts, from cellular functions to the identification of gene functions. Thus, an ever-increasing volume of the research has used network visualization to gain deep insight into the molecular interactions that influence our body functions.
Since the days of Flash have gone by, alternative technologies are rising. The interactive presentation used to be a dominion of Flash, It is no more same.
Cytoscape.js leads the game.
Cytoscape.js is an API (Application Program Interface, i.e., it specifies how software components should interact and used to program graphical user interface), which allows the user to assimilate graphs into interaction models and web user interfaces.
Cytoscape.js is a stand-alone tool and its architecture is broadly classified into two categories:
1. Core: The core is the main entry point for the developer. Core functions allow accessing graph elements. It represents the graph, and perform various operations on the graph.
2. Collection: It is a set of graph elements. It allows to filter, traverse, perform various operations. Sometimes, it is taken as an input by some core functions.

Cytoscape.js offers a different type of graphs such as directed, undirected, traditional, multigraphs and hypergraphs. The graphs can also be modified by adding or deleting the graph elements such as edges. It includes the Graph theory algorithm which enables the user to search for the shortest path in the interaction graph. The graph consists of nodes representing the unit i.e., a protein or a gene. These nodes can also be modified by removing or by selecting the interested nodes only. The graph can be saved either in PNG or JPG format.
Cytoscape.js is an open source software and is available at http://js.cytoscape.org. It is an improvisation over the Adobe Flash-based Cytoscape Web.
In this demo, you can drag individual nodes, zoom in and perform other routine activities.

Kpax is a bioinformatics program to search and align protein structures . 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…)
How to run do_dssp command (mkdssp) in Gromacs 2022?
In the latest version of GROMACS (2022) , there are some issues regarding the gmx do_dssp command. Apparently, this command either does not run displaying a fatal error, or if it runs then it does not read any frame from MD simulation files. In this article, we are going to run the same command for GROMACS 2022. (more…)
