I am analyzing a microarray dataset composed by 32 samples and 50.000 genes. My goal is to create some gene networks, more precisely, I want to know the interaction type between genes (activation/inhibition for example)
I found some interesting modules using the WGCNA package. In each module, genes are more or less highly connected and I want to discover the nature of this connection.
Working on each module separately to build one gene regulatory network by module was my idea.
The question is : Is this method biologically or mathematically relevant ?
Thanking you in advance.
