subject.morph.standard: Retrieve standard space morphometry data for a single subject.

Description

Load standard space morphometry data (like 'surf/lh.area.fwhm10.fsaverage.mgh') for a subject from disk. Uses knowledge about the FreeSurfer directory structure to load the correct file.

Usage

subject.morph.standard(subjects_dir, subject_id, measure, hemi,
  fwhm = "10", template_subject = "fsaverage", format = "mgh")

Arguments

subjects_dir,

string. The FreeSurfer SUBJECTS_DIR, i.e., a directory containing the data for all your subjects, each in a subdir named after the subject identifier.

subject_id,

string. The subject identifier

measure,

string. Name of the vertex-wise measure of morphometry data file. E.g., "area" or "thickness". Used to construct the name of the morphometry file to be loaded.

hemi,

string, one of 'lh', 'rh', or 'both'. The hemisphere name. Used to construct the names of the annotation and morphometry data files to be loaded.

fwhm,

string. Smoothing as string, e.g. '10' or '25'.

template_subject,

string. Template subject name, defaults to 'fsaverage'.

format,

string. One of 'mgh', 'mgz', 'curv'. Defaults to 'mgh'.
