Search rRFs by biogenesis on precursor rRNAs. (A,B) Secondary structures of rRNAs in the large ribosomal subunit. The shade of color in each circle represents the total CLASH chimeric reads supporting the rRFs covering that nucleotide. As the linear scale indicates a few regions of most abundance of rRFs and may seem too faint (A), so users may opt for a differently shaded log scale (B). The colormaps reflect coverage by all chimeric reads, not only those passing the default filters. (C) rRFs presented after clicking the nucleotides pointed by arrows in A,B with default filters for rRFs supported by at least five CLASH chimeric reads and five UHs. Ten first lines with rRFs are shown, red letters indicate a motif for one of the rRFs. As is common, motif significance comes hand in hand with the high read count (RC) and UH support.
