[Insight-users] how to use DeformableRegistration4 for dicom file?

[he smth]

hi all,
it always tells me that BSplineDeformableTransform: Mismatched between
prarmeters size and region size.
what does it mean?
my dicom files are both 256*256, while the image files in this
example(RatLungSlice1.mha and RatLungSlice2.mha) are 128*128.
