[Insight-users] doubt about DeformableRegistration1 and resampling

Hi All,

I have a question.
I am registering CT image with MR image of different healthy subjects.
I use non rigid registration in particular I run DeformableRegistration1.cxx


MRI:-> fixed image
size 176 256 160
spacing (1 1 1)mm
origin 0 0 0

CT immage: ->moving image
size 512 512 29
spacing (0.653595 0.653595 4)mm
origin 0 0 0


The registered image is not in the middle of FOV. It is always shifted in the down rigth corner.
I don't understand if my problem is a very bad choose of parameters (like E, number of integration points, ecc) or somethings else.
My guess is the resample step falls.
is it possible? any idea?

any suggestion is very appreciated.

Serena.
