I was thinking to modify a unit test to check ITK_non_uniform_sampling_deviation but I'm having a hard time finding a test that reads multiple dicom files. Many seem to read only a single file/slice. The test files also have weird file names, and symlinks, and it's all hard to untangle...

Anyone know of any?
