The AutoCN program
This program calculates the adjacency matrix, which keeps the information about connectivity of atoms in the crystal structure.

The Crystal Data window
This window allows you to look through and edit the crystal structure information.

The main features of the IsoCryst program
This program draws crystal structures and calculates their geometrical parameters.

The ToposPro Topological collections
These collections store the topological descriptors for classification of periodic nets.

The standard simplification method
This method allows you to construct underlying nets, which keep the information about connection of structural groups, and ignores the information about their geometrical properties and internal structure.

Special methods of simplification
This lesson describes the cluster, skeleton, edge net and ring net simplifications methods.
