Hi Tracy,
Yes, it is a bit circular in that you don't know the grid
until you get there, so making a grid template ahead of
time does not quite work. But the grid is based on
3dAllineate applying -dxyz 2.5 to the final anatomical
dataset, which is apparently a little different from
applying it to the template.
Or possibly, 3dAllineate's application of 2.5 mm is a
little different that that of 3dresample. I would have
to see where that is coming from...
To understand the missing +orig, would you please mail
me a proc script?
Thanks,
- rick
