Visualizing gene and gene isoform expression data in the cell line H929. This is a system generated graphic illustration of table 2. Section A shows the gene expression values for both the microarray and corresponding RNA-seq experiments. Here, for RNA-seq data, Log2(Expression) corresponds to Log2(FPKM). For microarray data, Log2(Expression) corresponds to the log2 function applied to the normalized absolute intensities from the microarray. Bar plots are used as a visualization aid for the tabular data, and are not meant as a direct comparison between the two different platform technologies. Section B shows an isoform-based comparison, on a gene-by-gene basis, for the RNA-seq gene expression values and allows for an easier identification of dominant forms.
