Figure 5From: From co-expression to co-regulation: how many microarray experiments do we need?Effect of the number of microarray experiments on the environmental stress data subset with 205 genes. Using SCPD as the evaluation criterion, we compared the extent of co-regulated genes using different numbers of microarray experiments on the subset of environmental stress data with 205 genes and 205 experiments at 20 clusters. The median z-scores (and hence, proportions of co-regulated genes) increase as the number of experiments increases, and MCLUST typically produces relatively high median z-scores. We observed very similar results using ChIP data as the evaluation criterion.Back to article page
