Replica Exchange Molecular Dynamics (REMD) Services


Replica Exchange Molecular Dynamics (REMD) Services

Molecular Dynamics (MD) simulation is a computer-based method to study the physical movements of molecules used extensively in the realm of chemical physics, biophysics, and materials science. As an extension of MD, Replica Exchange Molecular Dynamics (REMD) introduces the concept of performing simulations with multiple identical replicas of the system under different thermodynamic or Hamiltonian conditions to make the sampling more efficient. CD ComputaBio is a world-leading bioinformatics company specializing in mechanistic modeling, chemoinformatics, biology services, and more. We are proud to provide one of our latest services, REMD Services.

Algorithm in REMD Simulation

Enhanced Sampling

We employ a range of enhanced sampling techniques within our algorithm, such as replica-exchange metadynamics, umbrella sampling, and Hamiltonian replica exchange, to accelerate the convergence of simulations and improve sampling efficiency.

Machine Learning

To further optimize our REMD services, we have integrated machine learning algorithms into our platform. By leveraging machine learning models, we can enhance the accuracy of predictions and accelerate the identification of promising drug candidates.

Temperature Exchange

At the heart of our REMD services is a proprietary algorithm developed by our team of experts. Our algorithm incorporates a temperature exchange protocol that enables efficient exploration of the conformational space by enhancing the exchange of configurations between replicas.
