Supercell Step

GitHub pull requests Build Status Code Coverage Code Quality Documentation Status Updates for Dependencies PyPi VERSION

A SEAMM plug-in for building supercells of periodic systems.


  • Currently only accepts na, nb, and nc, the numbers of cells in the three directions.

  • To do:

    • Create a supercell with a minimum dimension, e.g. 10 Å.

    • Create orthorhombic cells from hexagonal ones.

    • Build using the primitive cell rather than conventional.


This package was created with Cookiecutter and the molssi-seamm/cookiecutter-seamm-plugin project template.

Developed by the Molecular Sciences Software Institute (MolSSI), which receives funding from the National Science Foundation under award OAC-1547580 and CHE-2136142.
