Hi Rick;

>I'd be happy to take a look

You should now have welling_2004_6_10.tgz in your upload area. To see the problem, please:

1) Untar it, creating the directory welling_2004_6_10
2) cd into the directory, which will contain the datasets warped_axial, norm_warped_axial, and test.
3) Use 3dinfo to verify that warped_axial+tlrc and norm_warped_axial+tlrc occupy the same volume.
4) Fire up afni, and:
a) select warped_axial as the anatomy and tlrc as the coordinate system.
b) select test as the functional
c) display the functional and note that it overlays the anatomy.
d) switch to norm_warped_axial as the anatomy and note that the functional is no longer in the picture.

Thanks! Any help would be greatly appreciated.
