Volcano plots for RNA-seq and Exon array. (A). p-value vs. log10 fold change (SCD vs. control) for RNA-seq data.(B). p-value vs. log10 fold change for Affymetrix human Exon array data. Points in the lower right and lower left hand corners of the plots represent transcript clusters that are significant and differentially expressed. ●Blue circles represent transcripts with a FC greater or equal to 4 in RNA-seq and Δ Red triangles represent FC greater or equal to 2 in Exon arrays. *Green asterisks represent transcripts with a FC greater than or equal to 4 on RNA-seq only.
