ETP program is designed to be a comprehensive package satisfying the versatile needs to study electron tunneling process in proteins.

ETP program is developed and maintained solely by Dr. Muhammad Hagras.

ETP Main Features:

- Different visualization schemes based on two OpenGL engines.

-  Different GUI interfaces to well-known packages including Gaussian program.

- Supports MM/MD simulation using AMBER force field.

- Tunneling pathway calculation and visualization using different schemes.
