mne.apply_forward¶

mne.apply_forward(fwd, stc, info, start=None, stop=None, verbose=None)[source]¶

Project source space currents to sensor space using a forward operator.

The sensor space data is computed for all channels present in fwd. Use pick_channels_forward or pick_types_forward to restrict the solution to a subset of channels.

The function returns an Evoked object, which is constructed from evoked_template. The evoked_template should be from the same MEG system on which the original data was acquired. An exception will be raised if the forward operator contains channels that are not present in the template.

Parameters:

Parameters:	fwd : Forward Forward operator to use. Has to be fixed-orientation. stc : SourceEstimate The source estimate from which the sensor space data is computed. info : instance of Info Measurement info to generate the evoked. start : int, optional Index of first time sample (index not time is seconds). stop : int, optional Index of first time sample not to include (index not time is seconds). verbose : bool, str, int, or None If not None, override default verbose level (see `mne.verbose()` and Logging documentation for more).
Returns:	evoked : Evoked Evoked object with computed sensor space data.

fwd : Forward

Forward operator to use. Has to be fixed-orientation.

stc : SourceEstimate

The source estimate from which the sensor space data is computed.

info : instance of Info

Measurement info to generate the evoked.

start : int, optional

Index of first time sample (index not time is seconds).

stop : int, optional

Index of first time sample not to include (index not time is seconds).

verbose : bool, str, int, or None

If not None, override default verbose level (see mne.verbose() and Logging documentation for more).

Returns:

evoked : Evoked

Evoked object with computed sensor space data.
