Fig. S3.

$Q$-function scores obtained trying to distinguish 2,500 particles near the center versus the edge of the thin film, as a function of the set of structure functions used. The three circles correspond to using only local structural information: $\{S\}$ are the standard softness, $\{S_2\}=\{S,G_{Q_l},G_{Y_{lm}}\}$, and $\{S_3\}=\{S_2,G_S\}$.The three diamonds correspond to adding dynamical information (logarithmically spaced data on the magnitude of particle displacement, $\mathrm{\Delta }{r}_i$, out to a maximum time of $t_i=2\tau ,200\tau ,2,000\tau$.
