I think what is happening here is you are thresholding at 2.3 in your FEAT analyses; the end product of which is a FEAT report telling you that the range is from 2.3 (min) to 3.4 (max).
When you overlay your thresholded zstat file on top of your 152MNI, you need to type 2.3 into the min box provided.
Try doing this and see what happens.

Subject: Re: [FSL] Discrepancies between feat output and fslview
I also want to add a couple more thing I noted. I opened up the thresh_zstat
in fslview, which should look like what is displayed on the feat report (and
it does as expected), and the threshold ranges from 0 to 2.9. Why does the
range on the feat report say 2.3 to 3.4 when the thresholded image goes from
0 to 2.9? Could someone please explain what is going on here?
Thanks for the help,
Lin
