Figure 2From: A computational procedure for functional characterization of potential marker genes from molecular data: Alzheimer's as a case study Heatmap for the proteomic signature. Heatmap representing the abundance of the 21 selected proteins by l 1 l 2FS . The thick black lines show the gene groups identified with the k-means clustering technique. The samples are divided in two classes: AD and control. The red and green colors represent high and low abundance respectively. For visualization purposes the expressions have been scaled between 0 and 1.Back to article page
