a C2-110, C2-94 b C2-73. Single-sample classification system composed of a tree view. The different colors in the figure represent different classification levels, from left to right, the size of the circle represents the abundance of species, and near the fulcrum are the name of the classification and its corresponding abundance value. c Visualization of most dominant species, proteobacteria and actinobacteria classification and phylogenetic information of C2-110 and C2-94. d Visualization of most dominant species, proteobacteria, actinobacteria and Firmicutes classification and phylogenetic information of C2-73
