I was wondering if someone might be able to explain why there are sometimes overlapping colors module color section of plots created by WGCNA
For example, in the manual network construction tutorial (2. Network construction and module detection -> b. Step-by-step network construction and module detection) on the WGCNA website, there is a lot of striation of the module color assignments, particularly on the left-side of the plot.
Intuitively, I would expect the color assignments (which correspond to branch cuts in the dendrogram above) to be sequential, and not mixed together in this manner -- e.g. all of the "magenta" module would be in one place, and so on.
Any ideas why the color assignments appear this way?
