Spot trajectories (part above) and mutual spot correlations: The over- and under-expression spot summary maps collect the red and blue spots observed in the individual portraits into one master map, respectively. The arrows roughly illustrate the time-trajectories of over- and under-expression spots before, during and after the isolation experiment (see also the individual SOM portraits shown in Figure 1a). The correlation and ant-correlation maps visualize mutual correlations between the spots in terms of the weighted topological overlap (wto) measures for positive and negative correlations, respectively. Spots are connected by lines for strong correlations/anti-correlations.
