Fig. 5. Representation of the similarity matrix for 5B. The atomic configurations, i.e. disks, on the three sketch-maps are color-coded according to their lattice energy (bottom right), class following the heuristic classification (top right) and cluster index (gray structure do not belong to a cluster) found using HDBSCAN* on the similarity matrix (left). The structural pattern of each cluster is illustrated with a top view of the 5B polymorphs.
