[Insight-developers] mutual information image to image metric

[Joshua Cates]

Registration folks,

I'm getting a new run-time exception in previously working code while
using MutualInformationImageToImageMetric in ImageRegistrationMethod with
GradientDescentOptimizer:

itk::ExceptionObject (0x81645a0)
Location: "Unknown"
File:
/home/sci/cates/itk/Insight/Code/Algorithms/itkImageToImageMetric.txx
Line: 91
Description: itk::ERROR: MutualInformationImageToImageMetric(0x81644c8):
FixedImageRegion is empty


Can't this ivar (metric::FixedImageRegion) be set by
ImageRegistrationMethod like it is in
MultiResolutionImageRegistrationMethod, or must the user now set it
explicitly?

Thanks,

Josh.
