Chemical Motif Identifier

Project description

ChemicalMotifIdentifier

PyPI Version PyPI Downloads

This repository contains the codes necessary to perform a chemical-motif characterization of short-range order, as described in our Quantifying chemical short-range order in metallic alloys paper and our Chemical-motif characterization of short-range order using E(3)-equivariant graph neural networks paper.

This framework allows for correlating any per-atom property to their local chemical motif. It also allows for the determination of predictive short-range chemical fluctuations length scale. It is based on E(3)-equivariant graph neural networks. Our framework has 100% accuracy in the identification of any motif that could ever be found in an fcc, bcc, or hcp solid solution with up to 5 chemical elements.

Instalation

# To install the latest PyPi release
pip install --upgrade chemicalmotifidentifier

# To install the latest git commit 
pip install --upgrade git+https://github.com/killiansheriff/ChemicalMotifIdentifier.git

You will also need to install torch, torch_scatter and torch_geometric.

Example of usage

A jupyter notebook presenting a few test cases can be found in the examples/ folder.
