Clustering of samples using RPKM values of sense transcripts.

<p>Hierarchical clustering of samples was performed using RPKM values of sense transcripts from all gene models. The trees were depicted with MeV [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0141586#pone.0141586.ref063" target="_blank">63</a>] by using average linkage distance measurement and Pearson’s correlation (A) and Spearman’s correlation (B). The vertical scale is correlation coefficient. Red dots indicate separated 2_Knot samples. Green, blue and yellow dots also indicate duplicate samples that are not located in a single clade.
