The easiest thing to do is to not worry about the glass brain view,
and just overlay your results on that subject's own structural image.
Assuming you have coregistered the functional images to the structural
image, this should line up fine. Within SPM, for example, you can do
this by selecting the "sections" button, and then just select the
subject's structural image.
Hope this helps!
Best regards,
Jonathan
