Visualization of the results after merging some of the gene families into one node. Some of the genes families present in the pathway were merged into single nodes. Those nodes are drawn as pie-chart, in which the number of slices equals to the number of gene merged. The colour, border and radius are preserved from the complete graph (Fig. 2 in Additional file 1). Average log fold-change is used as representative value, when the agreement between expression and interaction type is assessed
