mne.grade_to_vertices

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.

Parameters
subjectstr

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.

n_jobsint

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

verbosebool | str | int | 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.

Returns
verticeslist of array of int

Vertex numbers for LH and RH.
