<BODY>
<P><FONT SIZE=2>Hi Luis,</FONT>
<BR><FONT SIZE=2>I did try this but it is still writing this out as little endian. Is there a way to force it to write in big endian format or force byte swapping?</FONT></P>
<P><FONT SIZE=2>Thanks</FONT>

<P><FONT SIZE=2>Hi Radhika,</FONT>
</P>
<P><FONT SIZE=2>Yes, you can specify the desired Endian-ness</FONT>
<BR><FONT SIZE=2>when writing the image.</FONT>
</P>
<P><FONT SIZE=2>You simple need to create the ImageIO object</FONT>
<BR><FONT SIZE=2>on your own (not let the ImageIO factory do it</FONT>
<BR><FONT SIZE=2>for you) and invoke on it any of the following</FONT>
<BR><FONT SIZE=2>methods:</FONT>
</P>
<BR>
<P><FONT SIZE=2> SetByteOrder (ByteOrder _arg)</FONT>
<BR><FONT SIZE=2> SetByteOrderToBigEndian ()</FONT>
<BR><FONT SIZE=2> SetByteOrderToLittleEndian ()</FONT>
</P>
<BR>
<P><FONT SIZE=2>These methods are defined in ImageIOBase</FONT>
<BR><FONT SIZE=2><A HREF="http://www.itk.org/Insight/Doxygen/html/classitk_1_1ImageIOBase.html" TARGET="_blank">http://www.itk.org/Insight/Doxygen/html/classitk_1_1ImageIOBase.html</A></FONT>
</P>
<BR>
<P><FONT SIZE=2>The code will look like</FONT>
</P>
<P><FONT SIZE=2>typedef itk::MetaImageIO ImageIOType;</FONT>
</P>
<P><FONT SIZE=2>ImageIOType::Pointer metaIO = ImageIOType::New();</FONT>
</P>
<P><FONT SIZE=2> metaIO->SetByteOrderToBigEndian();</FONT>
</P>
<P><FONT SIZE=2> // XOR</FONT>
</P>
<P><FONT SIZE=2> metaIO->SetByteOrderToLittleEndian();</FONT>
</P>
<BR>
<P><FONT SIZE=2>typedef itk::ImageFileWriter< ImageType > WriterType;</FONT>
</P>
<BR>
<P><FONT SIZE=2>WriterType::Pointer writer = WriterType::New();</FONT>
</P>
<P><FONT SIZE=2>writer->SetImageIO( imageIO );</FONT>
<BR><FONT SIZE=2>writer->SetFileName("myfilename.mhd");</FONT>
</P>
<P><FONT SIZE=2>writer->SetInput( filter->GetOutput() );</FONT>
</P>
<P><FONT SIZE=2>writer->Update();</FONT>
</P>
<BR>
<BR>
<BR>
<P><FONT SIZE=2>Regards,</FONT>
