## Dataset Description
This dataset contains a collection of 3D atomistic datasets with force and energy labels gathered from a series of sources:
- [Open Catalyst Project](https://github.com/FAIR-Chem/fairchem)
- OC20, OC22, ODAC23
- [Materials Project Trajectory Dataset (MPtrj)](https://figshare.com/articles/dataset/Materials_Project_Trjectory_MPtrj_Dataset/23713842)
- [SPICE 1.1.4](https://www.nature.com/articles/s41597-022-01882-6)
## Dataset Structure
### Data Instances
For each instance, there is set of atomic numbers (`input_ids`), 3-D coordinates (`coords`), a set of forces per atom (`forces`), the total and formation energy per
system (`total_energy`/`formation_energy`) and a boolean `has_formation_energy` that signifies whether the dataset has a valid formation energy.

The numbers of atoms within each sample for each dataset varies but the number of samples for each dataset is balanced.
`MPtrj` and `SPICE` are upsampled 2x and 3x respectively to ensure a balanced dataset distribution. The datasets are
interleaved until we run out of samples where there are 3,160,790 systems from each dataset (2x MPtrj runs out of samples first).
