Caption of KEGGview and Graphviz Pathway figures

Each figure shows the KEGG representation of the enriched pathway.
The box of the genes which are expressed during the measured time period are colored.
Each gene-box is partioned into ten parts, each representing one time point, so that the whole time course for the gene is shown.
The colors represent the log2-foldchange between epi and ing expression levels. The log2FC is normalized to the range of -1 to 1.
When the gene is higher expressed in ing the color is in a shade of green, while it is red, when the gene is higher expressed in epi.
Grey color indicates a similar expression intenisy in both adipose tissues, and no filling means no expression was measured in both depots.
