Overexpression summary heatmap of selected global spots (A - H, see Figure 5 and Table 1) in all tissues studied. The tissues are grouped into different categories in horizontal direction (see the color bar on top of the map; the colors are assigned to the categories in agreement with Figure 1). Each spot refers to one row. The top-three overrepresented gene sets are assigned in the right part of the map. The expression scale refers to the metagene of maximum expression in the respective spot.
