WebDec 1, 2024 · 1) Is it usual or correct to set the window in the peak of the preceding component (the N2) or should one rather try to set the window so that it is on the flanks of the P3? 2) In some studies the onset of the area is determined by calculating 50% of the peak-to-peak amplitude (and the offset is set to the same Webnal as a measure of latency difference. We tested the performance of DTW by comparing it to 25% - 50% fractional area, peak and 50% fractional peak. In addi-tion to the default DTW we also tested the type IIa step pattern, which constraints the resulting warping path [2]. Data were obtained from a deception detection
