I tried to use vtkExtractVOI filter to take of the pillow covering the
baby face.

The volume dimensions are 512 X 512 X 123 Slices.

 vtkVolume16Reader v16
 v16 SetDataDimensions 512 512
 v16 SetDataByteOrderToLittleEndian
 v16 SetFilePrefix  "$VTK_DATA_ROOT/Data/temp/im"
 v16 SetImageRange 1 123
 v16 SetDataSpacing  50 50 1.25


vtkExtractVOI extract
 # extract SetInput [V16 GetOutput]
 extract SetVOI  0 300 0 300 50 50 (My problem is here)
 extract SetInput [v16 GetOutput]
 extract SetSampleRate 2 2 2

Thanks in Advance,
JJ
