Fig. 1From: DGCA: A comprehensive R package for Differential Gene Correlation AnalysisAn example demonstrating the theoretical difference between differential expression and differential correlation. The top panel shows the RNA expression levels for two example genes in two example conditions. The bottom left panel shows that both of these genes have decreased expression values from condition A to condition B. On the other hand, the bottom right panel shows that these genes have positive correlation in condition A but no correlation in condition B, which could not have been predicted on the basis of the differential expression relationships aloneBack to article page
