[Insight-users] Segmentation fault in DeformableRegistration1

[Serena Fabbri]

Hi All,
I have a problem with DeformableRegistration1.

I am registering 
fixed image: 
T1 MRI 
(176,256,160)  spacing(1,1,1)mm  origin (0,0,0)

moving image: 
CT image 
(512,512,29)  spacing (0.653595, 0.653595, 4)mm  origin (0,0,0)


I write the size of moving image in parameters file.

I get this error:

Segmentation fault


is it necessary to resample the moving image to fixed image before to register?

Thanks a lot.

Serena.
