I used WGCNA to construct co-expression network based on RNA_seq data from 18 samples. I got around 60 modules. Half of the modules have less than 100 genes. I selected several modules and plot the heatmap using the expression values. I found that nearly all of the modules I checked have two expression patterns. See one example below.
My questions: is it possible that I can adjust the parameters to separate this module into two different ones? How to do that? Or it's better I do the separation myself? Thanks.
