Who it is for
- Researchers analysing periodic crystal structures through Python.
How to use it
- Prepare the documented cell tuple and check coordinate conventions.
- Choose a symmetry or standardization routine from the API summary.
AIPOCH has not verified execution.
Read usage documentationInputs
- Lattice vectors, fractional atomic positions and integer species labels; selected symmetry tolerances.
Outputs
- Symmetry datasets or standardized cells, depending on the selected routine.

Access conditions
- BSD-3-Clause
- Tolerance affects symmetry determination; this capability does not predict material properties.
- Community indexing of core software only. External components, models, datasets and services have separate terms. Installation, scientific accuracy and suitability were not validated.
- Symmetry searches use distance tolerances; check symprec and coordinate conventions for your structure.
