SOVA (Structural Order Visualization and Analysis tools)

[ソヴァ]

Openness:3 ★★★
Document quality:2 ★★☆

A Python package and graphical user interface for extracting structural order in materials. From atomic structure data, it can extract various structural features such as polyhedra, rings, and cavities. It can also be used to calculate pair distribution functions and angular distributions, as well as structure factors obtained from neutron diffraction and X-ray diffraction.
