Classification of clusters with regard to strandedness, differential expression, and phasing. Venn diagrams indicating the classification of 21-mer clusters (left) and 24-mer clusters (right) according to three binary criteria: origin from dsRNA (ds) versus origin from ssRNA (ss) (solid gray circle), differentially expressed (diff expr) versus not differentially expressed (not diff expr) (dashed gray circle), and phased versus unphased (black circle). Small RNAs were classified as having originated from ssRNA if >80% of the small RNAs in the cluster were of the same polarity. Classification as differentially expressed was at the 99.9% confidence level and classification as phased was with a FDR of 1.2% for 21-mer clusters and 10% for 24-mer clusters.
