We have 3369 freesurfer 5.3 extractions stored on backup. It amounts to about 1.5TB of data. We would like to run the amygdala / hippocampal subField extraction on that data. I am hesitant to run the extraction on our backup copy so I was going to restore the data onto our servers and run from there. However 1.5TB is a lot to restore. Is there a file or directory list from the initial freesurfer extraction the subField calculation requires that could be restored in lieu of each subject's entire directory? 

Thank you,
Keith
