[Insight-users] Registration : how to begin?

[Magda NAY]

Hello,

I want to use Mutual Information Registration for PET/CT. 
I installed itk, I have my two raw volumes and the parameters file is OK, but when 
I try to run the program: 

Parsing input ... 
Fixed image filename: /Recalage_ITK/ct.raw
Big Endian: 1
Image Size: [512, 512, 189]
Image Spacing: [0.9375, 0.9375, 5]
Moving image filename: /Recalage_ITK/pet.raw
Big Endian: 1
Image Size: [128, 128, 239]
Image Spacing: [4.29688, 4.29688, 4.25]
Permute order: [0, 1, 2]
Flip axes: [0, 0, 0]
Number of levels: 4
Fixed image shrink factors: [2, 2, 1]

Translation scale: 320

Could you give me an idea how could I fix this problem?

Thank you
