Geometry optimization for quantum chemistry
Project description
GeomeTRIC
This is an open-source geometry optimization code for quantum chemistry. The code works by calling external software for the energy and gradient through wrapper functions. Currently Q-Chem, TeraChem Psi4, and Molpro are supported.

Quick Help
Package dependencies are: Python 2.7, 3.6+ NumPy, Scipy, NetworkX
To install the code, run "python setup.py install". To execute the geometry optimizer, run "geometric-optimize".
You will need a .xyz file for the coordinates and one of the supported quantum chemistry software packages. The supported packages are: TeraChem, Q-Chem, and Psi4. You can also call Gromacs for MM forces.
Please refer to the example calculations for how to run the code.
The commands to execute the code are contained in "command.sh".
