In particular, the truncated dendrogram of Figure shows the final 10 AEs considered in the analysis. The b AE collects all NP bulk environments. The ss and ss' AEs collect all sub-surface AEs: ss identify the AEs under the FCC(111) and FCC(001) NP faces and those under the NP edges, ss' identify the "non-standard" subsurface AEs under the vertexes and the convex elements. The c and c' AEs enclose the concave environments. The s, e and e' enclose all surface AEs: s collects the AEs proper of FCC(111) and FCC(001) faces, e and e' collects edge AEs, while v and v' those proper of vertexes. We used the "coarse-grained" SOAP dictionary for analyzing our MD simulations and distinguishing between native and non-native AEs emerging in the simulated NPs.
