FreeSurfer Troubleshooting Reconstruction Work Flow
Source the correct version of FreeSurfer:
source your_freesurfer_dir/SetUpFreeSurfer.csh
- Set your SUBJECTS_DIR variable to your subjects directory:
setenv SUBJECTS_DIR your_subjects_dir
Run the first step of recon-all. See the ReconAllDevTable for individual steps that will be run during the whole process.
recon-all -i invol1 -i invol2 -autorecon1 -subjid your_subject_name
where invol1 and invol2 are paths to your input files. You can use as many as necessary (i.e., -i invol3 -i invol4) and they can be in any format that is accepted by mri_convert
- Check the talairach transform:
tkregister2 --mgz --s your_subject_name --fstal
- For intructions on how to fix bad talairachs tranforms, refer to:
- ["FsTutorial/Talairach"]
- Check the skull strip:
tkmedit your_subject_name brainmask.mgz -aux T1.mgz
- For instructions on how to fix poor normalizations or skull strips, refer to:
After adding control points run the step [wiki:OtherUsefulFlags -autorecon2-cp] (this will run -normalization, using control points, and everything else through the end of -autorecon2.)
- After you have an accurate brain volume, run the next step of recon-all:
recon-all -autorecon2 -subjid your_subject_name
- Check the white and pial surfaces:
tkmedit your_subject_name wm.mgz rh.white -aux brainmask.mgz -aux-surface lh.white
- For intructions on editing the final surfaces, refer to:
After editing the wm.mgz volume run the step [wiki:OtherUsefulFlags -autorecon2-wm] (this will run -fill, using new wm.mgz volume, and everything else through the end of -autorecon2.)
After editing the brainmask.mgz volume run the step [wiki:OtherUsefulFlags -autorecon2-pial] (this will run -finalsurfs, using new brainmask.mgz volume, and everything else through the end of -autorecon2.)
- After you have accurate pial and white surfaces run the final step of recon-all:
recon-all -autorecon3 -subjid your_subject_name
