Sequence logos and analysis results from MetaLogo on the C-terminal sequences of the Coronavirus spike S1 protein. (A) Sequence logos for all the S1 C-terminal sequences. The left tree indicates the relationships among groups. The red dot on the tree indicates the group to which the target sequence (first sequence of the input) belongs. Conserved positions among groups are connected by colored bands. (B) Clustering result of sequence logo groups to reveal the relationships among them. (C) Distribution of pairwise distances of the nodes in the phylogenetic tree. (D) Taxonomy classifications of sequences in each group.
