[Insight-users] UpdateLargestPossibleRegion exception onlargeimage

[Normand Mongeau]

Well, I switched from a BSplineInterpolateImageFunction filter to a 
BSplineResampleImageFunction, and I no longer get the error.  Since it was 
the only change I made, I suspect there is a problem with the interpolation 
filter.

Thanks,

Normand
