Select source positions using a label.
list of dictThe source space.
LabelThe label.
None | int | instance of RandomStateA seed for the NumPy random number generator (RNG). If None (default),
the seed will be obtained from the operating system
(see RandomState for details), meaning it will most
likely produce different output every time this function or method is run.
To achieve reproducible results, pass a value here to explicitly initialize
the RNG with a defined state.
strThe 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.
str | NoneThe subject the label is defined for.
Only used with location='center'.
New in version 0.13.
NoneThe path to the directory containing the FreeSurfer subjects
reconstructions. If None, defaults to the SUBJECTS_DIR environment
variable.
New in version 0.13.
strThe 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.
