Hi Luis,
 
I have tried to run imageRegistration8 for Release version and it took 21 minutes :((. My machine spesification and the image size are the same as what I wrote on my last email (email attached). 
 
Thanks beforehand for your answer.
 
Best regards,
.Tanya.

No, it was Debug version.

Dimension:256, 256, 168

Voxel size(mm): 0.86,0.86, 1.5

The .img file is 21,500 KB


- PET image

Dimension: 128, 128, 94

Voxel size(mm): 2.0, 2.0, 3.0

Maybe I should try for Release. I ll tell you how it works in Release version.
