Fig. 2From: NGS data vectorization, clustering, and finding key codons in SARS-CoV-2 variationsResults of clustering using Density Based Spatial Clustering of Application with Noise (DBSCAN): a shows clusters containing over 1,120 data points, and b shows the types of variants tagged in each virus by colour: In (a), it can be seen that numerous viruses gather to form a specific cluster, and in (b), it can be seen that one cluster tends to consist of a specific mutant virusBack to article page
