We present a novel method to identify local structures in disordered systems according to topological criteria. Its effectiveness is demonstrated in the analysis of the atomic structures in the rapid cooling of silver liquid. The method is parameter free and scale independent, and can generally be used for structural analysis of amorphous systems involving atoms or particles at different length scales.
