What is the best way to choose 'ntw' using wavelet coherence?

I am comparing EEG signals. I don't know what the optimum value of ntw should be. It is the length of the smoothing window. The default is roughly half the length of the signal. Does anyone have any suggestions? Thanks Kim

NTW gives the order of a moving average filter on the wavelet coefficients so the optimum value depends really on what scales are most important for you and how noisy the signal is.
The default is the minimum of 20 and 1/20*length(signal) so how does that lead to 1/2 the signal length?
