Scattered plots of normalized data and unsupervised hierarchical clustering of the samples and genes. A. Raw intensity data was background-corrected and normalized as described in Materials and Methods. The normalized data from seven samples were plotted against one sample (SB13L-Intra). B. 1,115 most variable genes were used for hierarchical clustering among samples. The gene expression values were scaled by row and shown in the heat map.
