Hi Andreas,
Your brain is not registered to any template? So you cannot use atlases,
but you can still refer to peak of clusters of activation (assuming you've
done a functional study somehow lignting up your ROI). Based on them you
can create a ROI (eg spherical) in Marsbar toolbox and then export it as a
nifti image if you need this format.
Not sure if it answers your questions?
