I think all you have to do is convert the aparc.a2009s+aseg.mgz to nifti (mri_convert something.mgz something.nii.gz

Good afternoon all,
I was hoping to get some advice on how to approach this. Any and all feedback is much appreciated.
My group has been using FSL’s Feat to run analyses for our PET-MR project. Part of what we need to do next is create masks using fslmaths that overlay the significant clusters in the zstat images with different brain regions. We then extract standard uptake values (SUVs) from the clusters in each region for each subject so that we can graph them. The issue is that the Atlas in FSL is the Harvard-Oxford Cortical Structural Atlas, which has a broader parcellation of the cingulate cortex then we would like to use (just anterior/posterior).
Is there any way to use the Desterieux atlas with FSL? Or any way to do this same kind of analysis with Freesurfer?
I would really appreciate the help.
Best,
Hannah
