# ASE trajectory reader pro

Attention

This file format reader is written in Python and therefore is only available in OVITO Pro and the OVITO Python module.

Important

The file reader requires the ASE module to work. Without this Python module, trajectory files will not be recognized by OVITO Pro or the `import_file()` function. Thus, first make sure that ASE is installed in your Python interpreter or in the embedded interpreter of OVITO Pro. See ovitos_install_modules.

Loads particle coordinates from trajectory files of the Atomic Simulation Environment (ASE).

Internally, the file reader is based on the `ovito.io.ase.ase_to_ovito()` function, which converts ASE atoms objects to OVITO’s particle datasets.
