 The data comes in `.extxyz` format and we follow the units of style `real` from [LAMMPS](https://docs.lammps.org/units.html). Each entry correspondgs to an atomic configuration and includes the following fields:
 
-- **species**: The type of atom (e.g., C for Carbon, O for Oxygen (O), ...).
+- **species**: The type of atom (e.g., C for Carbon, O for Oxygen, ...).
 - **positions**: 3D atomic positions (in Angstroms).
 - **velocities**: 3D atomic velocities (in Angstroms per fs).
 - **displacements**: 3D atomic displacements to the new positions after time interval Δt (in Angstroms).
 - **update_velocities**: 3D atomic velocities at time interval Δt (in Angstroms per fs).
 - **timestep**: Time interval Δt (in femtoseconds).
 - **pbc**: Information about periodic boundary conditions (e.g., `T T T`).
-- **Lattice**: The lattice vectors of the simulation box.
+- **Lattice**: The lattice vectors of the simulation box (in Angstroms).
 - **num_atoms**: The total number of atoms in the system (first line).
