 1. **Accuracy.** MatPES is computed using static DFT calculations with stringent converegence criteria.
    Please refer to the `MatPESStaticSet` in [pymatgen] for details.
 2. **Comprehensiveness.** MatPES structures are sampled using a 2-stage version of DImensionality-Reduced
-   Encoded Clusters with sTratified ([DIRECT]) sampling from a greatly expanded configuration of MD structures.
