Introduction

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

What is `tng`

TRAJNG (Trajectory next generation) is a program library for handling molecular dynamics (MD) trajectories. It can store coordinates, and optionally velocities and the H-matrix. Coordinates and velocities are stored with user-specified precision. In addition, program specific information (text strings) can optionally be stored in the beginning of each file. Atomic labels can also optionally be stored once in the beginning of the file.

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