Figure 2

Correlation between some dinucleotide step parameters for RR, RY and YR type steps in free-RNA dataset. Panels (a-f) show the correlations between the same pairs of dinucleotide step parameters as shown in Figure1. A Mahalanobis ellipse fitted with the mean as centre. Correlation coefficient (r) and best-fit line calculated for each group, are also shown. An 'r' value ≥ 0.14, ≥ 0.18, ≥0.18 is significant at 99.9% confidence level for RR, RY and YR steps respectively. The data points as well as ‘r’ values for RR, RY and YR steps are shown in red: RR (n = 347), blue: RY (n = 210), green: YR (n = 240).
