MatPL

Dataset Description

The MatPL dataset is an example dataset for training material potentials with OneScience/NEP. It contains multiple material systems, including AuAg, Cu, HfO2, and LiSiC, and covers the pwmat/movement, pwmlff/npy, and extxyz data formats. The data include atomic coordinates, simulation cell information, energies, and forces for different material systems in different configurations, and serve as a standard benchmark dataset for learning and validating machine-learning interatomic potential methods such as NEP.

The current data package contains approximately 636 files and is approximately 38 MB in size.

Supported Tasks

This standardized data repository provides the complete data package for the official MatPL examples, including four material systems. It can be used for:

• Training and validation of machine-learning interatomic potential models
• Potential energy surface fitting for material simulations
• Functional testing and benchmark evaluation of the NEP framework
