Dataset Name

water ice NEP 2023

Description

The main part of the dataset consists of structures of liquid water at 300 K from first-principles molecular dynamics (FPMD) simulations using a hybrid density functional with dispersion corrections. The dataset is expanded to include nuclear quantum effects by adding structures from path-integral molecular dynamics (PIMD) simulations. The final dataset contains 814 structures of liquid water at different temperatures and pressures, water slab, and ice Ih and ice VIII. These systems cover a wide range of structural and dynamical properties of water and ice. This dataset builds on the dataset from Schran, et al (2020) https://doi.org/10.1063/5.0016004

Usage

  • ds.parquet : Aggregated dataset information.
  • co/ directory: Configuration rows each include a structure, calculated properties, and metadata.
  • cs/ directory : Configuration sets are subsets of configurations grouped by some common characteristic. If cs/ does not exist, no configurations sets have been defined for this dataset.
  • cs_co_map/ directory : The mapping of configurations to configuration sets (if defined).

ColabFit Exchange documentation includes descriptions of content and example code for parsing parquet files:
