Data workflow and analysis summary.

<p>An overview of experimental and data analysis workflow adopted in the study for identification of known and putative novel cardiac chamber-restricted protein coding genes. (B) Venn diagram representing the total number of known protein coding genes (7,260) identified with expression level > = 10 FPKM across the three cardiac chambers. (C) A heat map representing expression pattern of 7,260 RefSeq protein coding genes with expression level > = 10 FPKM in the three cardiac chambers. The colour key represents transcripts in the range of 0 for transcripts with least expression to 15 for transcripts with maximum expression.
