Hierarchical clustering was also performed with a more stringent set of DE lncRNAs between WT and BRAFV600E, which allowed the clustering of two groups enriched with WT and BRAFV600E patients, respectively (Supplemental Fig. S2B). Clustering lncRNAs by Spearman correlation among all DE lncRNAs also identified two groups highly positively correlated or negatively correlated lncRNAs (Supplemental Fig. S3B).
