Dear guys, I tried to replicate the WGCNA tutorial step by step (https://horvath.genetics.ucla.edu/html/CoexpressionNetwork/Rpackages/WGCNA/Tutorials/FemaleLiver-05-Visualization.pdf) Therefore I used the code exactly the same as the tutorial. However I got the TOM heatmap like this, with red background and golden modules. It's so wired that the colors are opposite to the figure in the tutorial. I googled a lot and found no similar phenomenon. How could I get this TOM heatmap like the tutorial? Thanks very much.
