MPinterfaces is a python package that enables high throughput Density Functional Theory(DFT) analysis of arbitrary material interfaces(two dimensional materials, hetero-structure, ligand capped nanoparticles and surfaces in the presence of solvents) using VASP, VASPsol, LAMMPS, materialsproject database as well as their open source tools and a little bit of ase.

Installation

Install Pymatgen

See http://pymatgen.org/#getting-pymatgen

Note: for hpg2 users refer to ufhpc_readme.md in the docs and follow it for installation

Get the latest version

If you already have a local copy, steps 1 and 2 of the following instructions can be skipped. Just do a “git pull” from the MPInterfaces folder and go to step 3(if the local copy was installed in the develop mode this step can be skipped too).

1. Clone the latest version from github

• git clone https://github.com/henniggroup/MPInterfaces.git

2. cd MPInterfaces
3. python setup.py install(or develop)
4. (optional) Copy the config.yaml file to mpinterfaces/config_mine.yaml and update the file so that you have the following environment variables :
   • MAPI_KEY=the_key_obtained_from_materialsproject
   • VASP_PSP_DIR=path_to_vasp_potcar_files

Documentation

A very minimal documentation is avaiable at

http://henniggroup.github.io/MPInterfaces/

and work is underway to improve it.

Usage

We use pymatgen tools for all structure manipulation tasks, so it would be a good idea to start from here:

http://pymatgen.org/#using-pymatgen

The examples folder contain some sample scripts that demonstrate the usage of mpinterfaces as well as materialsproject packages. For basic usage please see docs/usage.rst.
