[vtkusers] Error occurs when reading series of DICOM slices data

[David Gobbi]

Hi Sally,

The vtkDICOMImageReader does not support compressed data.  You
must use "Decompress selected DICOM files" in Osirix before the
vtkDICOMImageReader can read them.  If that doesn't fix the problem,
then you can try using GDCM to read your images.
