mne.sensitivity_map#

mne.sensitivity_map(fwd, projs=None, ch_type='grad', mode='fixed', exclude=[], verbose=None)[source]#

Compute sensitivity map.

Such maps are used to know how much sources are visible by a type of sensor, and how much projections shadow some sources.

Parameters:
fwdForward

The forward operator.

projslist

List of projection vectors.

ch_type‘grad’ | ‘mag’ | ‘eeg’

The type of sensors to use.

modestr

The type of sensitivity map computed. See manual. Should be ‘free’, ‘fixed’, ‘ratio’, ‘radiality’, ‘angle’, ‘remaining’, or ‘dampening’ corresponding to the argument –map 1, 2, 3, 4, 5, 6 and 7 of the command mne_sensitivity_map.

excludelist of str | str

List of channels to exclude. If empty do not exclude any (default). If ‘bads’, exclude channels in fwd[‘info’][‘bads’].

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:
stcSourceEstimate | VolSourceEstimate

The sensitivity map as a SourceEstimate or VolSourceEstimate instance for visualization.
