The original surface models contained in this directory were created by 
Peggy Christidis using FreeSurfer http://surfer.nmr.mgh.harvard.edu/

The anatomical data set is an average of 27 scans obtained from 
MNI http://www.bic.mni.mcgill.ca/ and UCLA  http://www.loni.ucla.edu/
   Holmes, C.J., Hoge, R., Collins, L., Woods, R., Toga, A.W. and Evans, A.C. 1998 
   Enhancement of Magnetic Resonance Images Using Registration for Signal Averaging. 
   J. Comp. Asst. Tomograph, 22(2):324-333.

Talariach transformation of the anatomical data set was performed using 
AFNI http://afni.nimh.nih.gov

Talariach transformation of the surface models was performed using SUMA's
ConvertSurface program http://afni.nimh.nih.gov/ssc/ziad/SUMA

To view function on the Talariach surface:
   (we'll call TLRC_SURF, the directory where the Talairach surface models reside.)
1- From TLRC_SURF directory, make a copy of TT_N27+tlrc data set and place it in the directory where your functional
data resides (we'll call that directory FUNC_DATA).
   3dcopy TT_N27+tlrc FUNC_DATA/SomePrefixYouLikeToUse
2- From FUNC_DATA directory, launch afni with the -niml option
      afni -niml &
3- From FUNC_DATA directory,launch SUMA with the tlrc.spec files and use the copy of TT_N27+tlrc for the surface volume.
      suma -spec N27_both_tlrc.spec -sv TT_N27+tlrc. &

NOTE: 
   Only the smoothwm, white and pial surfaces have been transformed to Talairach space. The other surfaces are left untouched. 
   Therefore, the surface area and enclosed volume of the transformed surfaces have changed.
   
   
New surfaces recreated by Patricia Christidis, Dec 04. 
   - correct left right labels!
   - full hemisphere flattening
   - addition of skull stripped brain

TT_N27 is now the same dset used to display Eickhoff and Zilles' database. Feb. 06
