piv_clustering
structural clustering of atomic trajectories based on PIV
...Alternatively, also the SPRINT topological coordinates can be employed, that are particularly suited for nanostructures.
The output is a partitioning of the trajectory into a few structural clusters (i.e., sets of frames), allowing for simpler analysis and visualization.
