Figure 2From: Filtering of false positive microRNA candidates by a clustering-based approachSimilarity analyses of a clustered miRNA with four groups of sequences. A clustered miRNA is aligned with sequences from four categories: (i) miRNA(s) in the same cluster; (ii) miRNAs outside its cluster; (iii) random sequences extracted from the genome; and (iv) random sequences extracted from its flanking 3000 nt region.Back to article page
