mne.time_frequency.compute_raw_psd¶

mne.time_frequency.compute_raw_psd(raw, tmin=0.0, tmax=None, picks=None, fmin=0, fmax=inf, n_fft=2048, n_overlap=0, proj=False, n_jobs=1, verbose=None)¶

Compute power spectral density with average periodograms.

Parameters:

raw : instance of Raw The raw data. tmin : float Minimum time instant to consider (in seconds). tmax : float | None Maximum time instant to consider (in seconds). None will use the end of the file. picks : array-like of int | None The selection of channels to include in the computation. If None, take all channels. fmin : float Min frequency of interest fmax : float Max frequency of interest n_fft : int The length of the tapers ie. the windows. The smaller it is the smoother are the PSDs. n_overlap : int The number of points of overlap between blocks. The default value is 0 (no overlap). proj : bool Apply SSP projection vectors. n_jobs : int Number of CPUs to use in the computation. verbose : bool, str, int, or None If not None, override default verbose level (see mne.verbose).

Returns:

psd : array of float The PSD for all channels freqs: array of float : The frequencies
