mne.viz.plot_snr_estimate(evoked, inv, show=True, axes=None, verbose=None)[source]#

Plot a data SNR estimate.

Parameters
evokedinstance of Evoked

The evoked instance. This should probably be baseline-corrected.

invinstance of InverseOperator

The minimum-norm inverse operator.

showbool

Show figure if True.

axesinstance of Axes | None

The axes to plot into.

New in version 0.21.0.

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
figinstance of matplotlib.figure.Figure

Notes

The bluish green line is the SNR determined by the GFP of the whitened evoked data. The orange line is the SNR estimated based on the mismatch between the data and the data re-estimated from the regularized inverse.

New in version 0.9.0.
