Visualizing microarray and RNA-Seq gene expression data with IGV. Joint visualization in IGV of three datasets: two microarray (GSE20711 and ISDB6354) and one RNA-Seq (GSE27003). The three datasets share the ER pathway activation status annotation (ER+/ER-). The top part of the central panel displays gene expression heatmaps. The bottom view displays the splice variants for the RNA-Seq dataset. The view is zoomed in on the locus containing an example gene, GREB1, in chromosome 2 that is regulated in the two microarray datasets.
