Hi FreeSurfers,

I want to obtain a template mri annotated according to the Destrieux atlas.

I found an mgz file in FreeSurfer/subjects/cvs_avg35_inMNI152/aparc.a2009s+aseg.mgz.

I read it with a FieldTrip function (ft_read_mri) and I get an atlas with 16777216 voxels.

On the other hand, when I read the annotation files (?h.aparc.a2009s.annot), I get 16399385 voxels.

Can anybody help me by indicating the correct file? I am also confused if the file should be an annot file or an mgz one.

I am quite ignorant but I hope I am clear enough.

thank you in advance,

Chrysa
