get.atlas.region.names(
  atlas,
  template_subjects_dir = NULL,
  template_subject = "fsaverage",
  hemi = "lh"
)

Arguments

atlas,

string. The atlas name. E.g., "aparc", "aparc.2009s", or "aparc.DKTatlas". Used to construct the name of the annotation file to be loaded.

template_subjects_dir,

string. The directory containing the dir of the template_subject. E.g., the path to FREESURFER_HOME/subjects. If NULL, env vars will be searched for candidates, and the function will fail if they are not set correctly. Defaults to NULL.

template_subject,

string. The subject identifier. Defaults to 'fsaverage'.

hemi,

string, one of 'lh' or 'rh'. The hemisphere name. Used to construct the names of the annotation and morphometry data files to be loaded. Defaults to 'lh'. Should not matter much, unless you do not have the file for one of the hemis for some reason.

Value

vector of strings, the region names.
