How To Install packmol on CentOS 8

packmol is Packing optimization for molecular dynamics simulations

Introduction

In this tutorial we learn how to install packmol on CentOS 8.

What is packmol

Packmol creates an initial point for molecular dynamics simulations by packing molecules in defined regions of space. The packing guarantees that short range repulsive interactions do not disrupt the simulations. The great variety of types of spatial constraints that can be attributed to the molecules, or atoms within the molecules, makes it easy to create ordered systems, such as lamellar, spherical or tubular lipid layers. The user must provide only the coordinates of one molecule of each type, the number of molecules of each type and the spatial constraints that each type of molecule must satisfy. The package is compatible with input files of PDB, TINKER, XYZ and MOLDY formats.

We can use yum or dnf to install packmol on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install packmol.

Install packmol on CentOS 8 Using dnf

Update yum database with dnf using the following command.

sudo dnf makecache --refresh

The output should look something like this:
