[Insight-users] "too many samples map outside..." - ImageRegistration5

[Matt McCormick]

Hi Tim,

This means the images are probably not overlapping at all.  If it
happens at the beginning, the transform parameter initialization is
suspect.  If it happens after many iterations, the optimizers settings
or the metric settings are suspect.

Hope this helps,
Matt
