Nature of problem:
Determining crystal structure parameters of a material is a quite important issue in crystallography. Knowing the crystal structure parameters helps to understand physical behavior of material. For complex structures, particularly for materials which also contain local symmetry as well as global symmetry, obtaining crystal parameters can be quite hard.
The tool extracts crystal parameters such as primitive vectors, basis vectors and identify the space group from atomic coordinates of crystal structures.
Assumptions are explained in the paper. However, none of them can be considered as a restriction onto the complexity of the problem.
All the examples presented in the paper take less than 30 seconds on a 2.4 GHz Pentium Pro computer.
