brainprep.interfaces.freesurfer_features_summary

brainprep.interfaces.freesurfer_features_summary(workspace_dir, output_dir)

Summarizes the generated FreeSurfer features for all subjects.

Generate text/ascii tables of FreeSurfer parcellation stats data ‘?h.aparc.stats’ for both templates (Desikan & Destrieux) and volumetric data for subcortical brain structures ‘aseg.stats’. Parcellation stats includes: - area - volume - thickness - thicknessstd - meancurv - gauscurv - foldind - curvind

Parameters:

workspace_dir: Directory

Working directory where FreeSurfer outputs are reorganized to run new commands.

output_dirDirectory

FreeSurfer working directory containing all the subjects.

Returns:

statfiles: tuple[File]

A tuple containing FreeSurfer summary stats. The data are returned in the following order (the results for each timepoint are stacked): - desikan_stat_lh_<meas>_file - destrieux_stat_lh_<meas>_file - desikan_stat_rh_<meas>_file - destrieux_stat_rh_<meas>_file - volume_stat_file

Notes

• Creates FreeSurfer ‘SUBJECTS_DIR’ for each timepoint in a working directory using symlinks.
