[Insight-users] MatrixOffsetTransformBase Error from AffineTransform

[Mehmet Suzen]

Dear List,

Trying to write a registration pipeline, following this;

	AffineTransform 
	MutualInformationImageToImageMetric 
	VersorRigid3DTransformOptimizer
	LinearInterpolator

I have set AffineTransform all 12 parameters in 3D as follows:

	transform->SetParameters( initialParameters );
	registration->SetInitialTransformParameters(
transform->GetParameters() );

And initial parameters really contain 12 parameters but I am getting the

following error, any ideas what can cause this?

itk::ExceptionObject (0x2ac2bd0)
Location: "void itk::MatrixOffsetTransformBase<TScalarType,
NInputDimensions, NOutputDimensions>::SetParameters(const typename
itk::Transform<TScalarType, NInputD
imensions, NOutputDimensions>::ParametersType&) [with TScalarType =
double, unsigned int NInputDimensions = 3u, unsigned int
NOutputDimensions = 3u]"
