PyXtal is an open source Python package which was initiated by Qiang Zhu and Scott Fredericks. The goal of PyXtal is to develop a fundamental library to allow one to design the material structure with a certain symmetry constraint. These structures can exported to various structural formats for further study. See the documentation for more information.
To contribute to this project, please check How to contribute?.
- Generation of atomic structures for a given symmetry and stoichiometry (0-3D)
- Generation of molecular crystals (1-3D) with the support of special Wyckoff positions.
- Structure manipulation via subgroup/supergroup symmetry relation
- Geometry optimization from built-in and external optimization methods.
- Internal support of
ciffile and many other formats viapymatgenorASE. - Easy access to symmetry information (e.g., Wyckoff, site symmetry and international symbols).
- X-ray diffraction analysis and its online application
To install the code, one just needs to do
pip install pyxtalor
pip install --upgrade git+https://github.com/MaterSim/PyXtal.git@masterIf you want to add the Julia package install (required by the use of pyxtal.lego module), please use
export INSTALL_JULIA=1 && pip install pyxtal To check if the installation is successful, run the following script,
from juliacall import Main as jl
jl.seval("using CrystalNets")
