OVITO (Open Visualization Tool) is a scientific data visualization and analysis software for atomistic and particle simulation data. Version 3.15.3 supports Python 3.10+. It provides a Python module for scripting data import, modification, visualization, and analysis. The library is under active development by OVITO GmbH.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

ovito

✓ import ovito

The main entry point; all modules are accessed via ovito.io, ovito.modifiers, ovito.data, etc.

DataCollection

✓ from ovito.data import DataCollection

After loading a simulation file, the pipeline's compute method returns a DataCollection object.

Load a simulation file, add a modifier to select atoms, compute the pipeline, and print the count.

import ovito from ovito.io import import_file from ovito.modifiers import SelectTypeModifier pipeline = import_file('simulation.dump') mod = SelectTypeModifier(types=['Atom']) pipeline.modifiers.append(mod) data = pipeline.compute() print(data.attributes['SelectType.count'])

Debug

Known issues

breakingOVITO 3.0+ uses a new Python API that is not backwards compatible with OVITO 2.x scripts.

fix

Rewrite scripts to use the new module structure (e.g., ovito.io instead of ovito.import_file). Refer to the migration guide.

affects: >=3.0

gotchaThe ovito Python module is only available in the OVITO Python interpreter or when installed via pip. Running 'import ovito' in a standard Python environment may fail if the OVITO conda/pip package is not installed.

fix

Install OVITO via 'pip install ovito' or use the bundled Python interpreter that comes with the OVITO desktop application.

affects: all

gotchaModifiers are applied lazily: calling pipeline.compute() is required to get the data. Reading data before compute returns an empty DataCollection.

fix

Always call pipeline.compute() before accessing data or attributes.

affects: all

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'ovito'

OVITO Python package not installed in the current environment.

fix

Run 'pip install ovito' or install the OVITO conda package.

AttributeError: module 'ovito' has no attribute 'import_file'

Importing from the wrong module path: ovito.import_file is deprecated since OVITO 3.0.

fix

Use 'from ovito.io import import_file' instead.

RuntimeError: This operation is not supported in the current interpreter mode

Attempting to use ovito in a non-OVITO Python interpreter without a valid license or without installing the pip package.

fix

Ensure you have installed 'ovito' via pip and have a valid license if required for certain features.
