A Phylogenetic relationship between the target OTU (OTU3438) and its neighboring OTUs. B OTU phylogenetic correlation rℓm under different values of the tuning parameter c, illustrated by setting m = OTU3438 as the target OTU. The x-axis is the OTUs shown in the same order as the tree tips. The y-axis is rℓm, the correlation between OTU3438 and the remaining OTUs
