Figure 2. Clustering identification of the 59 SARS-CoV-2 potential variants (PVs).
Spatial distribution of the 59 identified clusters on a t-distributed stochastic neighbor embedding (t-SNE) map. The L strain sequence is highlighted in black, the 59 PVs (i.e., medoids of each cluster) are highlighted in red, and the active potential variants (i.e., validated for Fc-Ace2 binding and/or infectivity) are highlighted in green.
