mne.read_surface¶

mne.read_surface(fname, read_metadata=False, return_dict=False, file_format='auto', verbose=None)[source]¶

Load a Freesurfer surface mesh in triangular format.

Parameters

fnamestr

The name of the file containing the surface.

read_metadatabool

Read metadata as key-value pairs. Only works when reading a FreeSurfer surface file. For .obj files this dictionary will be empty.

Valid keys:

‘head’ : array of int

‘valid’ : str

‘filename’ : str

‘volume’ : array of int, shape (3,)

‘voxelsize’ : array of float, shape (3,)

‘xras’ : array of float, shape (3,)

‘yras’ : array of float, shape (3,)

‘zras’ : array of float, shape (3,)

‘cras’ : array of float, shape (3,)

New in version 0.13.0.

return_dictbool

If True, a dictionary with surface parameters is returned.

file_format‘auto’ | ‘freesurfer’ | ‘obj’

File format to use. Can be ‘freesurfer’ to read a FreeSurfer surface file, or ‘obj’ to read a Wavefront .obj file (common format for importing in other software), or ‘auto’ to attempt to infer from the file name. Defaults to ‘auto’.

New in version 0.21.0.

verbosebool | str | int | None

Control verbosity of the logging output. If None, use the default verbosity level. See the logging documentation and mne.verbose() for details. Should only be passed as a keyword argument.

Returns

rrarray, shape=(n_vertices, 3): Coordinate points.
trisint array, shape=(n_faces, 3): Triangulation (each line contains indices for three points which together form a face).
volume_infodict-like: If read_metadata is true, key-value pairs found in the geometry file.
surfdict: The surface parameters. Only returned if return_dict is True.
