Hi Joel,

Actually, this is normal, though it may seem a little strange.
The basic point is that the warps are applied to the datasets
(and in fact, must be applied to your test dataset, because it
doesn't have a tlrc view).

So in tlrc view, the test dataset must be warped. But since
there is no warped test data, the warp in the current tlrc
dataset is applied. But in the case of the norm_warped_axial
dataset, it's transformation does not apply to the test dataset,
and the warp throws it out of range.

You need to do 2 things:

1. Actually write out the test+tlrc dataset. To do this, use
warped_axial as the underlay and test as the overlay, go into
the tlrc view, and "write -> Olay".

2. Move the test+orig dataset out of the current directory.

Now the Talairach viewing should be fine.

I am not quite sure why step 2 is necessary. But it most likely
goes back to the fact that afni assumes that all datatsets in a
single directory are registered. Even if you are using tlrc view,
the orig datasets are still there.

You may also want to write out the tlrc view of warped_axial.
