Evaluation of single-pMMS and differential-pMMS configurations. a and b show NRMS errors of single-pMMS half-amplitude and half-frequency sweep trials (S.H.H), single-pMMS full-amplitude and full-frequency sweep trials (S.F.F.), and differential-pMMS full-amplitude and full-frequency sweep trials (D.F.F.). c and d indicate R-value of S.H.H., S.F.F., and D.F.F. Data are reported as mean ± 1 S.D. Asterisks above bars indicates significant differences between different pMMS configurations. * p<1×10−3, ** p<5×10−4, *** p<1×10−4, **** p<5×10−5, one-way ANOVA with Tukey-Kramer multiple comparison tests. Where no significance was seen, a p value is shown
