mne.time_frequency.csd_multitaper(epochs, fmin=0, fmax=inf, tmin=None, tmax=None, picks=None, n_fft=None, bandwidth=None, adaptive=False, low_bias=True, projs=None, n_jobs=1, verbose=None)

Estimate cross-spectral density from epochs using a multitaper method.

Parameters

epochsinstance of Epochs

The epochs to compute the CSD for.

fminfloat | None

Minimum frequency of interest, in Hertz.

fmaxfloat | numpy.inf

Maximum frequency of interest, in Hertz.

tminfloat

Minimum time instant to consider, in seconds. If None start at first sample.

tmaxfloat | None

Maximum time instant to consider, in seconds. If None end at last sample.

picksstr | list | slice | None

Channels to include. Slices and lists of integers will be interpreted as channel indices. In lists, channel type strings (e.g., ['meg', 'eeg']) will pick channels of those types, channel name strings (e.g., ['MEG0111', 'MEG2623'] will pick the given channels. Can also be the string values “all” to pick all channels, or “data” to pick data channels. None (default) will pick good data channels (excluding reference MEG channels). Note that channels in info['bads'] will be included if their names or indices are explicitly provided.

n_fftint | None

Length of the FFT. If None, the exact number of samples between tmin and tmax will be used.

bandwidthfloat | None

The bandwidth of the multitaper windowing function in Hz.

adaptivebool

Use adaptive weights to combine the tapered spectra into PSD.

low_biasbool

Only use tapers with more than 90% spectral concentration within bandwidth.

projslist of Projection | None

List of projectors to store in the CSD object. Defaults to None, which means the projectors defined in the Epochs object will by copied.

n_jobsint

The number of jobs to run in parallel (default 1). If -1, it is set to the number of CPU cores. Requires the joblib package.

verbosebool | str | int | None

Control verbosity of the logging output. If None, use the default verbosity level. See the logging documentation and mne.verbose() for details. Should only be passed as a keyword argument.

Returns

csdinstance of CrossSpectralDensity

The computed cross-spectral density.
