mne.grade_to_vertices(subject, grade, subjects_dir=None, n_jobs=1, verbose=None)[source]

Convert a grade to source space vertices for a given subject.


Name of the subject.

gradeint | list

Resolution of the icosahedral mesh (typically 5). If None, all vertices will be used (potentially filling the surface). If a list, then values will be morphed to the set of vertices specified in in grade[0] and grade[1]. Note that specifying the vertices (e.g., grade=[np.arange(10242), np.arange(10242)] for fsaverage on a standard grade 5 source space) can be substantially faster than computing vertex locations. Note that if subject=’fsaverage’ and ‘grade=5’, this set of vertices will automatically be used (instead of computed) for speed, since this is a common morph.

subjects_dirstr | None

The path to the freesurfer subjects reconstructions. It corresponds to Freesurfer environment variable SUBJECTS_DIR.


The number of jobs to run in parallel (default 1). Requires the joblib package.

verbosebool, str, int, or None

If not None, override default verbose level (see mne.verbose() and Logging documentation for more). If used, it should be passed as a keyword-argument only.

verticeslist of array of int

Vertex numbers for LH and RH.
