What wavelets function we can use in wtmm(Wavelet transform modulus maxima) and of what length of data we can use in wtmm?

I am trying to use wtmm function, but my signal is of gaussian type, so could i change the wavelet function used in wtmm?

What max length of signal i can use in wtmm, as i have close to 1lakh data points in my signal?

Hello Shweta,

I reckon the wtmm() function can handle 100000 data points. Also if your signal is of the Gaussian type, you need not change the mother wavelet as by default wtmm() uses the Mexican hat wavelet which is a second-derivative of a Gaussian.

Good luck!
