mne.minimum_norm.source_band_induced_power(epochs, inverse_operator, bands, label=None, lambda2=0.1111111111111111, method='dSPM', nave=1, n_cycles=5, df=1, use_fft=False, decim=1, baseline=None, baseline_mode='logratio', pca=True, n_jobs=1, prepared=False, verbose=None)

Compute source space induced power in given frequency bands

Parameters:

epochs : instance of Epochs

The epochs.

inverse_operator : instance of inverse operator

The inverse operator.

bands : dict

Example : bands = dict(alpha=[8, 9]).

label : Label

Restricts the source estimates to a given label.

lambda2 : float

The regularization parameter of the minimum norm.

method : “MNE” | “dSPM” | “sLORETA”

Use mininum norm, dSPM or sLORETA.

nave : int

The number of averages used to scale the noise covariance matrix.

n_cycles : float | array of float

Number of cycles. Fixed number or one per frequency.

df : float

delta frequency within bands.

use_fft : bool

Do convolutions in time or frequency domain with FFT.

decim : int

Temporal decimation factor.

baseline : None (default) or tuple of length 2

The time interval to apply baseline correction. If None do not apply it. If baseline is (a, b) the interval is between “a (s)” and “b (s)”. If a is None the beginning of the data is used and if b is None then b is set to the end of the interval. If baseline is equal ot (None, None) all the time interval is used.

baseline_mode : None | ‘logratio’ | ‘zscore’

Do baseline correction with ratio (power is divided by mean power during baseline) or zscore (power is divided by standard deviation of power during baseline after subtracting the mean, power = [power - mean(power_baseline)] / std(power_baseline)).

pca : bool

If True, the true dimension of data is estimated before running the time frequency transforms. It reduces the computation times e.g. with a dataset that was maxfiltered (true dim is 64).

n_jobs : int

Number of jobs to run in parallel.

prepared : bool

If True, do not call prepare_inverse_operator.

verbose : bool, str, int, or None

If not None, override default verbose level (see mne.verbose).

Returns:

stcs : dict with a SourceEstimate (or VolSourceEstimate) for each band

The estimated source space induced power estimates.
