Multilayer omics data and clustering. Three data types are considered: proteins in the upper layer; gene expressions in the middle layer; and CNVs in the lower layer. One dot represents one variable. Two dots are connected by a line if the corresponding variables are interconnected). Left panel: the true data structure with four clusters. Middle panel: MuNCut clustering. Right panel: K-means clustering. For K-means and MuNCut, different clusters are represented using different colors. a Truth. b MuNCut. c K-means
