    ERmod

    Approximate solvation free energy calculator

    ERmod (Energy Representation Module) is a program to calculate the solvation free energy based on the energy representation method (J. Chem. Phys. 113, 6070 (2000)). The program allows users to calculate the solvation free energy to arbitrary solvents, including inhomogeneous systems, and can run in cooperation with state-of-art molecular simulation software, such as LAMMPS, GROMACS and/or AMBER.

    MESMER is designed to analyze and simulate reactions in the gas phase that take place on a potential energy surface that is characterized by having one or more potential wells, and which are typically described by rate coefficients that depend on pressure (or concentration) as well as temperature. MESMER allows you to simulate systems over a wide range of pressures and temperatures, extract rate coefficients, analyze experimental data, fit model parameters and represent rate coefficients in formats that can be used directly in large scale simulations (e.g. ...

    Argo

    Argo

    ARGO is a program for analysis of electronic structure calculations

    The `Argo' program draws its name from ancient Greek, referencing the vessel of the same name commissioned for Jason's renowned Argonauts expedition. This choice symbolizes the pursuit of making the best use of quantum chemical calculation results. ARGO facilitates the analysis of results obtained from quantum chemistry codes, specifically Gaussian. This task is achieved through a set of Python scripts. Our code is freely available throughout the academic community with the ambition to...

    ParamIT

    a Toolset for Molecular Mechanical Force Field Parameterization

    ...The developed tools include: 1) generator of molecule-water complexes with graphical user interface (GUI), 2) semi-automatic frequency analysis using symbolic potential energy distribution matrix and comparison of optimized internal coordinates, 3) GUI for charge fitting with three modes: manual, Monte-Carlo sampling or brute force, and 4) GUI for dihedral terms fitting. The usage of these tools decreases the labor effort, lowers manual input errors and reduces the time needed for accurate MM parameterization efforts.
