Heatmap and unsupervised hierarchical clustering of genes changed in Array-191 and cell lines used (built using R package ‘pheatmap’). Each row represents the gene that had a change in at least one cell line, and each column represents the cell line used in the experiment. Preferential exon exclusion shown in blue; preferential exon inclusion shown in red. The Euclidean distance metric was used for clustering, while the linkage was done using the “ward.D” algorithm
