# mne.simulation.select_source_in_label¶

mne.simulation.select_source_in_label(src, label, random_state=None, location='random', subject=None, subjects_dir=None, surf='sphere')[source]

Select source positions using a label.

Parameters
src

The source space

labelLabel

random_stateNone | int | instance of RandomState

If random_state is an int, it will be used as a seed for RandomState. If None, the seed will be obtained from the operating system (see RandomState for details). Default is None.

locationstr

The label location to choose. Can be ‘random’ (default) or ‘center’ to use mne.Label.center_of_mass() (restricting to vertices both in the label and in the source space). Note that for ‘center’ mode the label values are used as weights.

New in version 0.13.

subject

The subject the label is defined for. Only used with location='center'.

New in version 0.13.

subjects_dir

Path to the SUBJECTS_DIR. If None, the path is obtained by using the environment variable SUBJECTS_DIR. Only used with location='center'.

New in version 0.13.

surfstr

The surface to use for Euclidean distance center of mass finding. The default here is “sphere”, which finds the center of mass on the spherical surface to help avoid potential issues with cortical folding.

New in version 0.13.

Returns
lh_vertnolist

selected source coefficients on the left hemisphere

rh_vertnolist

selected source coefficients on the right hemisphere
