The first number of each cell is the optimal cluster number and the second number is the Silhouette score. The optimal cluster number corresponding to the maximum score was picked from a limited series of cluster numbers (k ≤ 10)
^aBeta matrix was applied as the input
^bCoordinate (PC1–PC3) of each sample was applied as the input. Coordinate was generated by the classical multidimensional scaling method from the beta matrix
