Figure 7

The data rotation. An illustration of the data rotation. Present (dark gray) and divergent (light gray) genes are presumed to group themselves into a V-shaped pattern in the MA-plot. The divergent genes populates along a line of slope -2 (broken line). After rotation the A* axis will be parallell to this line, and genes can be ranked according to their M*-value.
