Dataset Name

ANI-1xnr

Description

ANI-1xnr was developed to train the ANI-1xnr model, intended to model reactive chemistry. Specifically, ANI-1xnr is meant to represent carbon solid-phase nucleation, graphene ring formation from acetylene, biofuel additives, combustion of methane and the spontaneous formation of glycine from early earth small molecules. The dataset was generated using an active learning method in which ab initio nanoreactor simulations supplied MLIP training; the MLIP was subsequently tested and new simulations were generated based on structures tested with high uncertainty to supply the next cycle of MLIP training.

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:
