hi all,

i am trying to read stimulate file, by using metaImage header. (since i have already program using metaImage format) 

For this, i create .mhd file.  Original .spr file (header file for stimulate format) and my .mhd file are as follows:

.spr file

numDim: 4

dim: 256 256 24 1

interval: 0.625000 0.625000 3.000000 1.0

dataType: WORD

sdtOrient: ax

endian: ieee-be

.mhd file

NDims = 4

DimSize = 256 256 24 1

ElementSpacing = 0.625000 0.625000 3.000000 1.0

Position = 0 0

ElementByteOrderMSB = True

ElementType = MET_SHORT  ( i tried wtih MET_USHORT as well since i am not sure

if WORD is MET_USHORT or MET_SHORT )

HeaderSize = -1

ElementDataFile = shilpa_magI_001.raw

when i try to read raw file using above header file, i get following error message

ElementType required and not defined.
MetaObject: Read: MET_Read Failed
MetaImage: M_Read: Error parsing file
MetaImage: Read: Cannot parse file
Exception caught during Raw file reading

itk::ExceptionObject (00F1F520)
Location: "Unknown"
File: C:\Insight1.2\Code\IO\itkImageIOBase.cxx
Line: 122
Description: itk::ERROR: MetaImageIO(00228ED0): Unknown pixel type: 0

I am not able to find out what exactly is wrong.  I think I am specifying MET_USHORT in incorrect way.  Any input on this is appreciated.

Thanks,

Neha
