TopologyFinder
Script for determining the topology of the crystal structure from the CIF file. The procedure for determining the topology includes the detection of chemical bonds in the crystal structure, the identification of the structure belonging to one of the chemical classes with the fixation of building units, the simplification of the structure to the base grid, the calculation of a set of topological indices, and the determination of the topology of the base grid from the base of topological types.

OxidationStatePredictor
Script for determining the degree of oxidation for metal atoms in an oxygen environment according to the CIF file. The procedure for calculating the degree of oxidation is based on a predictive scheme detailed in the article. The position of an atom in the periodic system and the geometric characteristics of its Voronoi polyhedron in the crystal structure are used as descriptors.

StructureStability
Script for determining the stability of intermetallic compounds based on CIF file data. The calculation procedure is based on an analysis of the density of the spherical packing, in which the sizes of the balls correspond to the radii of the metal atoms; the method is described in detail in the article. The script allows you to calculate stability factors for the entire structure and for each individual atom of the structure, provided that the atoms have a coordination number ranging from 6 to 24. In accordance with the values of the stability factors, the script automatically draws a conclusion about the geometric stability/instability of the structure as a whole or the environment specific atom. The script allows you to analyze both completely ordered and disordered structures of intermetallic compounds.

PathFinder
Script for determining the migration map of working ions from CIF and POSCAR files. The path search procedure based on analysis of distances between nearest neighbors and the crystallographic symmetry of atomic positions.
