This repository contains the data, scripts, and Jupyter notebooks associated with the manuscript "Resolving the body-order paradox of machine learning interatomic potentials" by Chong et al. (arXiv:2509.14146). It is organized into the following: == analysis_notebooks == This folder contains notebooks that were used to extract the model-specific body-order energy and force decomposition results, and also the scripts to generate the associated figures in the manuscript and its SI. == evaluation_xyzs == This folder contains all the evalutions of the 8-mers and m-mers that have been done with the models that have been trained within the study. == training_scripts == This folder contains the actual training scripts that have been used for the MLIP training for the study. == training_xyzs == This folder contains the ASE-compatible extended xyz files that served as training, validation, and test sets for the MLIP training and evaluation. == QMC_analysis_results == This folder contains the results of the QMC calculations performed for our study, the details of which appear in the Supporting Information of the manuscript above.
