Extended Data Fig. 4: Pairwise ANI and clustering of genomes with MAGs suggests population structure.

Genomes were compared pairwise using FastANI72 and the resulting ANI values were hierarchically clustered using a complete linkage algorithm. The resulting clusters are represented by a dendrogram on the top and are named, as referred to throughout the paper, on the side of the heatmap. Values representing comparisons of genomes from the two major clusters (containing MAG 61 and 73) are coloured in grey.
