All of the steps below are contained in the scripts file /Volumes/data9/surface/scripts/@prep_dir
To run this command first change into the directory where a subject's anatomy (in AFNI format) is stored in a file name ECanatavg. e.g.
/Volumes/data9/surfaces/scripts/@prep_dir ec subjname
Where ec is the two-letter experiment code and subjname is the subject's name in the format lastname_firstname. The scripts assumes that an anatomical named ECanatavg+orig exists in the current directory. e.g.
/Volumes/data9/surfaces/scripts/@prep_dir DB doe_jane
This will create surfaces in the directory doe_jane
Initial setup in /surfaces
Make subject directory in /Volumes/data9/surfaces
cd into directory
copy high resolution scans into afni directory
3dcopy /Volumes/data1/UT/CG/afni/CGanatr1+orig ./CGanatr1
Creating FreeSurfer Directory Structures for Individual Subjects
FreeSurfer requires a specific directory structure for each subject. In addition FreeSurfer requires that subjects’ directories be listed in the $SUBJECTS_DIR. Since this is an environment variable, it can be set at anytime:
set SUBJECTS_DIR = /surfaces/subject_name/
The program mksubjdirs constructs the directory structure automatically.
cd $SUBJECTS_DIR mksubjdirs subjID
Importing AFNI Files into FreeSurfer
The mri_convert program is used to convert the BRIK/HEAD files into the mgz format (gzipped MGH file),:
mri_convert $SUBJECTS_DIR/afni/subjIDanatr+orig.BRIK $SUBJECTS_DIR/subjID/mri/001.mgz
This should be repeated for every anatomical scan with the number scheme 001.mgz, 002.mgz, 003.mgz, etc.
mri_convert afni/CAavganat+orig.BRIK CA/mri/001.mgz
if the averaging is done in AFNI (recommended method).
Ignore warnings issued by Freesurfer about using only one anatomical scan
