Hi SPM folks-
I was trying to do some longitudinal structural imaging processing w/
DARTEL, but kept running into some issues. I had two waves of
structural data (2 High-res T1s) and I wanted to warp a subject's Time
1 scan to their Time 2 scan and then create a Time 2 template (which
all the Time 2 scans would be warped to). However, when I warped a
subject's Time 1 scan to their Time 2 scan, the output get shifted
down (and are greatly misregistered).
Examples:

-Time 1 data
http://tezpur.keck.waisman.wisc.edu/~hanson/GM_warped_dartel.png
-Time 1 data warped to Time 2
Neither the raw Time 1, nor the raw Time 2 data is that far down on
the screen. The registration algorithms seem to pushing things down.
Any thoughts on why this would be happening?
Best,
jamie.
