[Insight-users] Mean squares metric

[Lodron, Gerald]

Hi,

I am making 3D image registration of CT images where it is possible that the images have different sizes/spacings. Because of the same modality and performance reasons i want to use the mean squares metric with nearest neighbour interpolator. My printed iteratin event says following:


Iteration XX    Value 1.#QNAN   Position[*1.#QNAN, etc]

Does anyone know what i made wrong. Any suggestions which optimizer would work best?

Best regards
