Abstract

Abstract As molecular dynamics (MD) simulations continue to evolve into powerful computational tools for studying complex biomolecular systems, the necessity of flexible and easy-to-use software tools for the analysis of these simulations is growing. We have developed MDTraj, a modern, lightweight, and fast software package for analyzing \MD\ simulations. \MDTraj\ reads and writes trajectory data in a wide variety of commonly used formats. It provides a large number of trajectory analysis capabilities including minimal root-mean-square-deviation calculations, secondary structure assignment, and the extraction of common order parameters. The package has a strong focus on interoperability with the wider scientific Python ecosystem, bridging the gap between \MD\ data and the rapidly growing collection of industry-standard statistical analysis and visualization tools in Python. \MDTraj\ is a powerful and user-friendly software package that simplifies the analysis of \MD\ data and connects these datasets with the modern interactive data science software ecosystem in Python.
