Hi-

I think this tutorial would be relevant:
[afni.nimh.nih.gov]
... specifically:
[afni.nimh.nih.gov]

The table output by 3dClusterize provides coordinates in the space of your datasets; if your dsets are in MNI space, then so are the coordinates.

Additionally, AFNI's whereami function/program can find overlap with atlases. Daniel Glen has been working bring in more MNI atlases for things like this. See:
