【生信分析】基于TCGA肿瘤数据进行基因共表达网络分析

WGCNA概述

WGCNA（Weighted Gene Coexpression Network Analysis）是一个基于基因表达数据构建基因共表达网络的方法。WGCNA和差异基因分析的区别在于:

• 差异基因分析主要针对样本之间的差异，
• WGCNA主要针对基因之间的关系。

WGCNA原文

WGCNA begins with the understanding that the information captured by microarray experiments is far richer than a list of
differentially expressed genes. Rather, microarray data are more completely represented by considering the relationships 
between measured transcripts, which can be assessed by pai
