Thank you for the advice Abraham! I will look into the article and try changing the bandtolerance parameter.

Regards,
Christian

Calculating the boundaries of the bands when using wavelet is quite complex. If you want the details you can consult the attached article ...

You may try the bandtolerance parameter ad decrease it. However, a small value will lead to descending to lower levels in the frequency decomposition tree when looking for a suitable node cover for a fre-quency band. This menas that frequency resolution increases and tem-poral resolution decreases because of the Gabor-Heisenberg uncertainty principle for signals. See details in the article attached.

Error in LFmin setting of CalculatePowerBand() when using the wavelet method? [ reply ]

I have been using the CalculatePowerBand() function to calculate both the LF (0.04 - 0.15 Hz) and MF (0.07 - 0.15 Hz) activity by calling this function twice (using two different CreateFreqAnalysis() functions) with different settings for the LFmin. This is working fine when using the Fourier method (confirmed by obtaining different values for LF and MF), but for the wavelet method, the LF and MF values become exactly the same.
Does anyone have any advice on how to obtain both the LF and MF activity using the wavelet method?
