This file contains the regression results of the force field training compared to the ab-initio training data in the last training step. This file is written for ML_MODE = train, select.

A sample output should look like the following:

****************************************************************************************************
     Results at         52 MD step.

The first column contains the ab-initio data. The second column contains the fitted data.

  • Total energies (eV): The number of lines corresponds to the number of training structures (The number of configurations in the corresponding ML_ABN file).
  • Forces (eV ang.^-1): Contains 3 lines (Cartesian directions) for each atom in each training structure. The direction varies first, then the atoms, and last the training structures.
  • Stress (kbar): Contains 6 lines for the tensor components of each training structure.
