Top35 heat map of species abundance clustering: longitudinal are the sample information, horizontal are the species annotation information. The cluster tree on the left is a species cluster tree, and the contrast between the two groups is on the right. The corresponding value of the heat map is the Z value of the relative abundance of species in each row after the normalization treatment
