cosymlib

Cosymlib is a python library for computing continuous symmetry & shape measures (CSMs & CShMs). Although its main aim is to provide simple and ready-to-use tools for the analysis of the symmetry & shape of molecules, many of the procedures contained in cosymlib can be easily applied to any finite geometrical object defined by a set of vertices or a by mass distribution function.

The basic tasks included in the current version of cosymlib are:

1. Molecular structure analysis

   • Calculation of Continuous Shape Measures (CShMs)
   • Calculation of Continuous Symmetry Measures (CSMs)
   • Calculation of Continuous Chirality Measures (CCMs)

2. Electronic structure analysis

   • Pseudosymmetry analysis of molecular orbitals & wavefunctions
   • Continuous Symmetry & Chirality Measures for the molecular electron density
