Fieldtrip time frequency

WebJun 1, 2024 · In FieldTrip, a 500 ms Hanning taper can be used while in MNE-Python a single taper from the Slepian sequence is recommended. These will result in about ∼3 Hz spectral smoothing. For the faster frequency range (>30 Hz) we recommend a multitaper approach (Percival and Walden, 1993) with a 250 ms sliding time window and K = 5 WebIn FieldTrip, the time-frequency decomposition is computed by the function ft_freqanalysis, specifying one of the supported algorithms in cfg.method. The method mtmconvol implements a STFT, whereas the method wavelet is based on Morlet wavelets (a Morlet wavelet is a complex sinusoid tapered with a Gaussian function).
