Figure 5From: Correction of technical bias in clinical microarray data improves concordance with known biological informationBias correction improves concordance of replicates in a glioma gene expression study. Hierarchical clustering was performed as in Figure 1. (a) The unfiltered, uncorrected data results in neither of the two replicate pairs together. (b) Bias correction as described in this paper results in one of two replicate pairs clustered together.Back to article page
