[Insight-users] ImageToSpatialObjecMetric error

[flavio]

Hi to all itk user
I'm novice of itk and I'm trying to register a dicom image with a 
mesh_spatial_object of a mechanic frame using 
ImageToSpatialObjectRegistrationMethod
I wrote the code below , but i catch a strange error using 
ImageToSpatialObjectMetric (.... also if I used code from user manual)
Could you please help me ?

Best regards,
Flavio

---- CODE ----------
typedef itk::OrientedImage<unsigned short,3> ImageType;

// from pg 155 of manual
// definition of mesh
 typedef itk::DefaultDynamicMeshTraits< float , 3, 3 > MeshTrait;
 typedef itk::Mesh<float,3,MeshTrait> MeshType;
 typedef itk::MeshSpatialObject<MeshType> MeshSpatialObjectType;

....
// from model registration
// registration method
typedef itk::ImageToSpatialObjectRegistrationMethod< ImageType, 
MeshSpatialObjectType >RegistrationType;
RegistrationType::Pointer registration = RegistrationType::New();

// metric definition
typedef itk::ImageToSpatialObjectMetric< ImageType, 
MeshSpatialObjectType > MetricType;
MetricType::Pointer metric = MetricType::New();  // <- error is here

--------- ERROR -------------
