great, that worked, thank you!

after that I recon-all'ed the colin27 brain so that I could use vol2label and label2annot for a lh.aal.annot and rh.aal.annot.

Not that I know of. I played around a little with them. Below are my notes on getting it onto the colin27 brain. Good luck!

Downloaded AAL from http://www.gin.cnrs.fr/spip.php?article217,
specifically http://www.gin.cnrs.fr/AAL/aal_for_SPM8.tar.gz

The ROIs are in ROI_MNI_V4.nii, but they need to be left right
reversed

mri_convert ROI_MNI_V4.nii ROI_MNI_V4.lrrev.nii --left-right-reverse-pix

To map to the raw colin27 brain

 mri_label2vol --seg ROI_MNI_V4.lrrev.nii --temp colin27_t1_tal_lin.nii \
   --regheader colin27_t1_tal_lin.nii --o  ROI_MNI_V4.anat.lrrev.nii

Dear all,

does anyone know if there is a surface parcellation file based on the AAL for freesurfer? I am aware that I could recon-all the MNI brain and project the atlas on the surface. (but maybe someone already did that)

I spend some time googeling this, but haven't found it, therefore my question.

all the best,
Bastian
