[Insight-users] exception using 2D bspline deformable registration

[Sachin Jambawalikar]

Hi all,

I am using the example code DeformableRegistration4 to register   2D
slices of dynamci contrast breast mri data  .

I get the following exception:


ImageRegion (0033BF04)

  Index: [0, 0]
  Size: [512, 512]


ImageRegion (0033DEA4)
