WGCNA, analysis on two data sets

Hello, I have two healthy and cancer data sets and want to do WGCNA analysis. My goal is to detect the genes that are significant/different in these two data sets comparing to each other. My questions is should I follow the second part (II. Consensus analysis of female and male liver expression data) in this page: https://horvath.genetics.ucla.edu/html/CoexpressionNetwork/Rpackages/WGCNA/Tutorials/

Or the third tutorial also consider the traits in calculation? I didn't see anything related to traits identifying in Adjacency and TOM calculation. But gene significance calculation get the traits information. So I am confused how the traits information is been considered in analysis. I will be thankful if you advice me what is the best way to use WGCNA for two data sets analysis.

Thanks, Haleh

Please read question 1 of the FAQ: https://horvath.genetics.ucla.edu/html/CoexpressionNetwork/Rpackages/WGCNA/faq.html

TLDR: you don't have enough samples

Thank you for your response. I think my question wasn't clear. I have more than 20 samples, having two conditions (HC vs Non-HC). My question is when I have data sets of two conditions, how to use WGCNA that consider the condition in correlation calculation. What I see, even in Male and Female liver example, they do the analysis separately and then get the consensus one. Here I am not looking for consensus, I am looking for differences.

I will be thankful is someone can help me out. Thanks

Hello, how is everything? Have you had any opinions on this issue? If yes, you could share the information with me, because I am having the same problem.

Thank you
