<div><div></div><div class="h5"><br><br>Yes. That's right. Please feel free to contribute a patch. The gradient direction needs to be pre-multiplied by the measurement frame. You can externally do this before supplying the container of gradient directions to the filter.<br>
<br>Alternatively, you can use the Stochastic Tractography Filter in Slicer which does take the measurementframe into account.<br><br><a href="http://viewvc.slicer.org/viewcvs.cgi/*checkout*/trunk/Applications/CLI/DiffusionApplications/StochasticTractographyFilter/itkStochasticTractographyFilter.txx?rev=5439" target="_blank">http://viewvc.slicer.org/viewcvs.cgi/*checkout*/trunk/Applications/CLI/DiffusionApplications/StochasticTractographyFilter/itkStochasticTractographyFilter.txx?rev=5439</a><br>

Good morning,<div><br></div><div>i read that the DiffusionTensor3DReconstructionFilter does not take into account the measurement frame in gradient directions. żis it still working this way?</div><div><br></div><div>thanks,</div>
