Hello! I am working on a WGCNA analysis to find co-expressed genes between different cell types. I created multi expression matrix based on timepoints to find co-expressed genes. However, when I use the plotDendroAndColors function, I get an error that says " object 'moduleColor' not found."
I also wanted to know the minimum amount of samples required for the WGCNA analysis. Because, when I try to compare data of two replicates of a cell type with two other replicates of a different cell type, the function returns an error saying that the number of genes isn't enough.
Any other advice on how to go about the WGCNA consensus analysis will also be much appreciated.
