Please read the README.md in the repository linked below for instructions on how to extract the COMP6 HDF5 (extention *.h5) files. https://github.com/isayev/ANI1_dataset
The following paper contains a description of the file format: https://www.nature.com/articles/sdata2017193
These results represent the errors (MAE/RMSE) over the entire benchmark using a single ML potential (column 1). Please read https://aip.scitation.org/doi/abs/10.1063/1.5023802 Section IID for a detailed description of the error metrics.
Please contact Justin S. Smith at jussmith48@gmail.com if you'd like to add your results from the COMP6 benchmark.
