Setting Up

  • Note: I am using FS_0184 (semcat) as an example; fill in the parts specific to FS_0184 with the parts specific to your subject

This is an abridged version of the more detailed list provided elsewhere in the wii

Structural

  1. Slicer
    • In terminal, Slicer &
    • Load data brainmask.nii
    • Save data as brainmask.mgz
    • Results: creates brainmask.mgz file
  2. Autorecon 1
    • In terminal, autorecon1_SC.sh FS_0184
    • Don't bother editing after this step; skip to autorecon 2
    • Result: populates mri folder (includes "T1.mgz")
  3. Autorecon 2
    • In terminal, autorecon2_SC.sh FS_0184
    • Editing
      • One terminal, tksurfer FS_0184 lh inflated
      • In another terminal, tkmedit FS_0184 brainmask.mgz -aux T1.mgz -surfs
      • Look for any noticable spikes in the tksurfer brain and edit the brainmask (tkmedit). See wiki page for details; this is the most labor intensive part of anatomical so make sure you're doing it right.
    • Results: creates lh.cortex.label and rh.cortex.label in label folder
  4. Autorecon 3
    • In terminal, autorecon3_SC.sh FS_0184
    • Editing
      • In terminal, tksurfer -annot aparc FS_0184 lh pial
      • If needed, reference tksurfer -annot aparc fsaverage lh pial
      • Repeat with right hemi
      • Make sure to EXPORT ANNOTATION! Do not "save overlay!"
      • Again, be sure to see the autorecon3 page
    • Result: populates label folder (includes "lh.aparc.annot" and "rh.aparc.annot")
