eelbrain.VolumeSourceSpace

class eelbrain.VolumeSourceSpace(vertices, subject=None, src=None, subjects_dir=None, parc=None, connectivity='custom', name='source', filename='{subject}-{src}-src.fif')

MNE volume source space

Parameters:
vertices : list of 2 int arrays

The vertex identities of the dipoles in the source space (left and right hemisphere separately).

subject : str

The mri-subject name.

src : str

The kind of source space used (e.g., ‘ico-4’; only ico is currently supported.

subjects_dir : str

The path to the subjects_dir (needed to locate the source space file).

parc : None | str

Add a parcellation to the source space to identify vertex location. Only applies to ico source spaces, default is ‘aparc’.

connectivity : ‘grid’ | ‘none’ | array of int, (n_edges, 2)

Connectivity between elements. Set to "none" for no connections or "grid" to use adjacency in the sequence of elements as connection. Set to numpy.ndarray to specify custom connectivity. The array should be of shape (n_edges, 2), and each row should specify one connection [i, j] with i < j, with rows sorted in ascending order. If the array’s dtype is uint32, property checks are disabled to improve efficiency.

name : str

Dimension name (default "source").

filename : str

Filename template for the MNE source space file.
