Thank you very much. A last help, please. How is the anatomical file that I can use to overlay the masks. I'm noting that masks are characterized by:data_type INT32dim1 256dim2 256dim3 256dim4 1datatype 8pixdim1 1.0000000000pixdim2 1.0000000000pixdim3 1.0000000000pixdim4 0.0109999999cal_max 0.0000cal_min 0.0000file_type NIFTI-1+ Regards,

you can use mri_binarize on aparc+aseg, eg, something like
mri_binarize --i aparc+aseg.mgz --match 1003 1012 1014 1032 --o frontal.nii.gz
those numbers come from $FREESURFER_HOME/FreeSurferColorLUT.txt That table has a lot of ROIs in it, and not all will be in the aparc+aseg. You'll be interested in the ones between 1000-1035 and 2000-2035

Hi list,
I need to create a mask of frontal, parietal, temporal and occipital lobes in a subject by using cortical parcellation output.
Is it possible? Eventually, how can I transform these masks file to mii.gz (to import them in FSL analysis).
Thank you very much.
Regards,
Stefano
