MG can produce blank output when eroding non-binary WM mask #19

The erosion of the WM using itk::BinaryErodeImageFilter can fail. Changing to itk::GrayscaleErodeImageFilter appears to fix the problem.

I'm encountering blank outputs with MG for multiple scans. The masks contain 0's and 1's only, but the data type stored in the nifti format mask file is uint8. I will try what you suggested - is it simply changing itk::BinaryErodeImageFilter to itk::GrayscaleErodeImageFilter in petpvcMullerGartnerImageFilter.h (and using the corresponding #include)?
