[Insight-users] itk::Error MutualInformationImageToImageMetric

[suresh]

Hi Luis,
Hi all,

I'm working on MRI-SPECT registration problem.I'm experimenting on 
MultiResMIRegistration example, with my images which or of sizes
SPECT 128, 128, 48
MRI   256, 256, 120

it is throwing an ITK exception

itk::Error MutualInformationImageToImageMetric(00E04B0);All the 
sampled point mapped to outside of the moving Image.

I tried changing the number of iterations and learning rates.but 
could not get rid of the exception.

please anybody elaborate more on this exception and on how to fix 
this.

Thank you,

suresh
