[vtkusers] vtkImageReader and BrainWeb

[marcelo oliveira]

Hi user´s 

I downloaded a raw data from

http://www.bic.mni.mcgill.ca/cgi/brainweb1

with this info:

BrainWeb download: T1 ICBM normal 1mm pn0 rf0
Modality=T1, Protocol=ICBM, Phantom_name=normal,
Slice_thickness=1mm, Noise=0%, INU=0%
MINC volume info: 

image: signed__ short 0 to 4095
image dimensions: zspace yspace xspace
dimension name   length   step   start
 zspace           181      1      -72
 yspace           217      1      -126
 xspace           181       1      -90

and choose FileFormat: raw byte (unsigned)

and Now i want to visualize this volume:

   vtkImageReader *v16R = vtkImageReader::New();
   v16R -> SetDataScalarTypeToUnsignedChar( );
   v16R -> SetDataByteOrderToLittleEndian( );
   v16R -> SetFileDimensionality( 3 );
   v16R -> SetHeaderSize ( 0 ); 
   v16R -> SetDataExtent( 0, 181, 0, 217, 0,  181  );
   v16R -> SetDataOrigin( -90, -126, -72);
   v16R -> SetDataSpacing ( 1, 1, 1 );
   v16R -> SetFilePattern(  'teste.raw' );      
   v16R -> SetFilePrefix(  'teste.raw' );
   v16R -> SetDataMask( 0x7fff );
   v16R -> UpdateWholeExtent( );

I´m using VTK 4.2 and Borland C++ 5.0 on XP.

The images appers but in a wrong way !!!
How can solve this ???

thank´s a lot for your hints and time !!!!!
