[ITK-users] Geodesic level set error

[Sindhoor Bhat]

Dear Matt,

I've got error in Geodesic active contour level set segmentation :  saying
 itk::ERROR: GeodesicActiveContourLevelSetImageFilter(0000000004AC7160): Inputs do not occupy the same physical space! 

I searched a lot on solving this error. but none have replied. Can you pls tell how to solve this error?
(I'm trying to segment 3D dicom images)

thank you.
