MRI: Cortical Surface Models

There is a simple three step process for creating surface models. The steps assume that you are in the afni subdirectory of the subject for which a surface is to be created.

 cd /Volumes/data/UT/IZ/afni

Step 1: Prepare the FreeSurfer directory tree

 /Volumes/data/scripts/@prep_dir IZanatavg+orig.BRIK  

Step 2: Reconstruct the surface. Note that the name of the anatomy is not needed, but if you are using the up arrow in the UNIX shell to recall the last command and edit it, there is no need to delete the filename. This step takes many hours!

 /Volumes/data/scripts/@recon IZanatavg+orig.BRIK

Step 3: Finish the surface

 /Volumes/data/scripts/@finish IZanatavg+orig.BRIK

step 4: Check the created surface

 cd ..
 ./@ec

Or in a more economical way:

 set ec = IZ
 cd /Volumes/data/UT/{$ec}/afni
 /Volumes/data/scripts/@prep_dir {$ec}anatavg+orig.BRIK  
 /Volumes/data/scripts/@recon {$ec}anatavg+orig.BRIK
 /Volumes/data/scripts/@finish {$ec}anatavg+orig.BRIK
 cd ..
 ./@ec
