Molecular dynamics (MD) simulations have become a standard tool to correlate the structure and function of biomolecules, and significant advances have been made in the study of proteins and their complexes. A major drawback of conventional MD simulations is the difficulty and cost of obtaining converged results, especially when exploring potential energy surfaces containing considerable energy barriers. This limits the wide use of MD calculations to determine the thermodynamic properties of biomolecular processes. Alternatively, a wide range of Structure-Based Models (SBMs) has been used in the literature to unravel the basic mechanisms of biomolecular dynamics. In a recent article in JCIM, we introduce SBMOpenMM, a Python library to build force fields for SBMs, that uses the OpenMM framework to create and run SBM simulations. The code is flexible, user-friendly, and profits from the high customizability and performance provided by the OpenMM platform.
