Yes, you just need a registration file. You can use mri_label2vol passing the aal atlas with the --seg option

Dear,

Can I use Freesurfer to convert aal atlas 3 from the MNI space to the native space of the T1 sequence?

Thanks.

Hi Diógenes

If there are regions that are not in any of our parcellations that
you want to obtain measures for, you can manually label them on
the fsaverage surface, then use mri_label2label to map them to
each individual subject and use mris_anatomical_stats -l <label
name> to get the measures you want.

Cheers

Bruce

Dear,

I would like to know how do I get thickness and cortical volume
measurements of the piriform gyrus in Freesurfer version 7, as
well as other regions of the olfactory pathway.

Thanks.
