Supposing had run 100 permutations of my expression data in WGCNA using sampledBlockwiseModules() and I wanted to see if a module I had observed in a previous run of that same data was preserved (specifically if I am aiming to get the preservation statistics) how would i go about doing that? Is there a simple function in WGCNA that allows me to do that, as there are so many handy/elegant functions in the package?
