[Freesurfer] AAL atlas question

Hi FS community,

I have recon-ed a set of subjects and I was interested in also obtaining structural info (cortical thickness, gray matter volume, surface area etc.) based on a different atlas than the ones FS is using, and in particular the AAL atlas.

I was wondering whether my approach would be the correct one or whether there is another (better and more accurate) approach:

1) Convert the AAL atlas into a surface (with mri_vol2surf) from the MNI space into the native subjects' space, 2) Use mris_anatomical_stats to calculate the structural stats

Sorry for the potentially trivial question, and thank you for your time!

Best, Panos
