Example of an explanatory variable. Nucleotide sequences were used as explanatory variables (features) around cleavage sites (a) or in whole RNA (b). Search regions were comprehensively changed, and nucleotide frequencies were calculated in the selected region. Similar data processing was conducted in the whole RNA. Nucleotide frequencies were calculated in the 5′-UTR, CDS, 3′-UTR, or whole RNA and were also calculated in 50-nucleotide sequences from the 5’ or 3’ end of each region (5′-UTR, CDS, 3′-UTR, or whole RNA).
