1. Source the correct version of FreeSurfer:

source your_freesurfer_dir/SetUpFreeSurfer.csh

setenv SUBJECTS_DIR your_subjects_dir

mksubjdirs your_subject_name

4. Convert the DICOM files to .mgz files in the $SUBJECTS_DIR/your_subjects_name/mri/orig directory:

mri_convert your_dicom_file your_subject_name/mri/orig/001.mgz

If you have multiple scans from the same session, convert additional scans like:

mri_convert your_other_dicom_file your_subject_name/mri/orig/002.mgz

5. Start the script recon-all. See the BasicReconTable for individual steps that will be run.

recon-all -autorecon-all -subjid your_subject_name

6.1 Make sure the talairach subject is linked to $SUBJECTS_DIR
- if not: ln -s $FREESURFER_HOME/subjects/talairach $SUBJECTS_DIR/.
6.2 tkregister2 --mgz --s your_subject_name --fstal 6.3 Check the white and pial surfaces:
- tkmedit your_subject_name wm.mgz rh.white -aux brain.mgz tkmedit your_subject_name wm.mgz lh.white -aux brain.mgz
