voronota - 1.22.3149-2+b1 main

The analysis of macromolecular structures often requires a comprehensive
definition of atomic neighborhoods. Such a definition can be based on the
Voronoi diagram of balls, where each ball represents an atom of some van
der Waals radius. Voronota is a software tool for finding all the
vertices of the Voronoi diagram of balls. Such vertices correspond to the
centers of the empty tangent spheres defined by quadruples of balls.
Voronota is especially suitable for processing three-dimensional
structures of biological macromolecules such as proteins and RNA.
.
Since version 1.2 Voronota also uses the Voronoi vertices to construct
inter-atom contact surfaces and solvent accessible surfaces. Voronota
provides tools to query contacts, generate contacts graphics, compare
contacts and evaluate quality of protein structural models using
contacts.
