Figure 2From: Metabolite-based clustering and visualization of mass spectrometry data using one-dimensional self-organizing mapsVisualization of one-dimensional self-organizing map after clustering. 1D-SOM matrix after metabolite-based clustering with 33 prototypes. The horizontal and vertical dimensions correspond to prototypes and experimental conditions, respectively. The color of matrix elements represent (average) intensity values according to the color map on the right hand side.Back to article page
