mne.vertex_to_mni¶

mne.vertex_to_mni(vertices, hemis, subject, subjects_dir=None, mode=None, verbose=None)[source]¶

Convert the array of vertices for a hemisphere to MNI coordinates.

Parameters:

Parameters:	vertices : int, or list of int Vertex number(s) to convert hemis : int, or list of int Hemisphere(s) the vertices belong to subject : string Name of the subject to load surfaces from. subjects_dir : string, or None Path to SUBJECTS_DIR if it is not set in the environment. mode : string \| None Either ‘nibabel’ or ‘freesurfer’ for the software to use to obtain the transforms. If None, ‘nibabel’ is tried first, falling back to ‘freesurfer’ if it fails. Results should be equivalent with either option, but nibabel may be quicker (and more pythonic). verbose : bool, str, int, or None If not None, override default verbose level (see `mne.verbose()` and Logging documentation for more).
Returns:	coordinates : n_vertices x 3 array of float The MNI coordinates (in mm) of the vertices

vertices : int, or list of int: Vertex number(s) to convert
hemis : int, or list of int: Hemisphere(s) the vertices belong to
subject : string: Name of the subject to load surfaces from.
subjects_dir : string, or None: Path to SUBJECTS_DIR if it is not set in the environment.
mode : string | None: Either ‘nibabel’ or ‘freesurfer’ for the software to use to obtain the transforms. If None, ‘nibabel’ is tried first, falling back to ‘freesurfer’ if it fails. Results should be equivalent with either option, but nibabel may be quicker (and more pythonic).
verbose : bool, str, int, or None: If not None, override default verbose level (see mne.verbose() and Logging documentation for more).

Returns:

coordinates : n_vertices x 3 array of float: The MNI coordinates (in mm) of the vertices

Notes

This function requires either nibabel (in Python) or Freesurfer (with utility “mri_info”) to be correctly installed.
