Hi All,

This is a little off topic in the context of Material Studio, but is there any known code for finding the Qn distribution in glasses? Qn distribution is the number of tetrahedra sorrounding by any tetrahedra. For example for silica glass Qn distribution is Q4(100% maybe). That means every Si tetrahedra is surrounded by 4 other Si tetrahedra. similary, for aluminosilicate glass it can be Q4Si (4Al) or Q4Si (3Al) which means Si tetrahedra is surrounded by 4 and 3 Al tetrahedra respectively. Does anybody know about any known scripts to find such distribution? I need to find the distribution in a glass system. Thanks!
