The rotation operation DtiStudio provides is for visualization only and should not be used for any quantification purpose.<br><br>If you need to reorient you data (including image registration, normalization, standardization, alignment, etc), you should use DiffeoMap, UNLESS you are talking about image registration of intra-DTI dataset<br>
<br>As someone asked before, there are several ways to reorient your DTI data; <br><br>1) Reorient original DWI before tensor calculation. We do not support this approach.<br>2) First calculate a tensor and reorient the tensor map. This is possible by DiffeoMap. Please load the tensor map by the "load *.d" button so that DiffeoMap knows that it has to perform tensor reorientation.<br>
3) First calculate a tensor and then FA map. Then reorient the FA map by DiffeoMap. <br><br>Susumu<br><br><div class="gmail_quote">On Wed, Jul 28, 2010 at 10:57 PM, [Seongjin] <span dir="ltr"><<a href="mailto:choisj70@gmail.com">choisj70@gmail.com</a>></span> wrote:<br>
