In simulations of individual systems, such as yFis1(TA) peptide in a micelle with 50 and into Figure ). This analysis reveals that helicity correlates with T 2 and hetNOE values with Pearson correlation coefficients of -0.57 and 0.79, respectively, while the correlation with T 1 values is weaker with a Pearson correlation coefficient of -0.15. However, spin relaxation times depend also upon other properties besides helicity that vary between systems, such as micelle size. Therefore, we also calculated Pearson correlation coefficients between helicity and spin relaxation times separately for each individual simulation in Fig. ). In all individual simulations, correlation coefficients between helicity and hetNOE values are above 0.5, with p-values below 0.05. In the case of T 2 values, all the systems have correlation coefficients with helicity below -0.45 with p-values below 0.05 except for three systems (two replicas of hMff(TA) with 45 SDS molecules and a GWALP monomer with 50 SDS molecules) for which significant correlation was not found (correlation coefficients around -0.25 with p-values around 0.2). In the case of T 1 values, negative correlation with helicity with correlation coefficients below -0.5 and p-values below 0.05 are common, yet significant correlation is not found in many systems and some systems have also significant positive correlation.
