Introduction

In the realm of molecular modeling and visualization, PyMOL has emerged as a powerful tool for researchers and scientists. Its versatility and user-friendly interface have made it a go-to choice for a wide range of applications, from protein structure analysis to molecular dynamics simulations. One of the key features that sets PyMOL apart is its ability to integrate with other tools and plugins, expanding its capabilities and making it an even more valuable resource for researchers. In this article, we will delve into the world of MSMS Plugin for PyMOL, a program that provides a graphical user interface to run MSMS and view its results in PyMOL.

What is MSMS?

MSMS, or Molecular Surface Modeler, is a software tool used to compute the solvent-excluded surface (SES) of a molecule. This surface represents the region of space that is inaccessible to a solvent molecule, such as water, due to the presence of the molecule's atoms. The SES is an important concept in molecular modeling, as it can be used to study protein-ligand interactions, predict binding sites, and analyze the accessibility of a protein's surface.
