mne.simulation.simulate_stc

mne.simulation.simulate_stc(src, labels, stc_data, tmin, tstep, value_fun=None)

Simulate sources time courses from waveforms and labels

This function generates a source estimate with extended sources by filling the labels with the waveforms given in stc_data.

By default, the vertices within a label are assigned the same waveform. The waveforms can be scaled for each vertex by using the label values and value_fun. E.g.,

# create a source label where the values are the distance from the center labels = circular_source_labels(‘sample’, 0, 10, 0)

# sources with decaying strength (x will be the distance from the center) fun = lambda x: exp(- x / 10) stc = generate_stc(fwd, labels, stc_data, tmin, tstep, fun)

Parameters:

src : list of dict

The source space

labels : list of Labels

The labels

stc_data : array (shape: len(labels) x n_times)

The waveforms

tmin : float

The beginning of the timeseries

tstep : float

The time step (1 / sampling frequency)

value_fun : function

Function to apply to the label values

Returns:

stc : SourceEstimate

The generated source time courses.
