When did you last update your itkv4. We recently restored itkBSplineTransform and added a new class, itkBSplineDeformableTransform with the new API.<br><br>Bill<br><br><div class="gmail_quote">On Mon, Sep 5, 2011 at 9:25 AM, Vivien Delmon <span dir="ltr"><<a href="mailto:vivien.delmon@creatis.insa-lyon.fr">vivien.delmon@creatis.insa-lyon.fr</a>></span> wrote:<br>

<br>
I am porting clitk tools to itk4 and I saw that the itkBSplineTransform's API changed. I tried to understand how it works with the example you wrote here : <a href="http://www.itk.org/Wiki/ITK/Examples/Registration/ImageRegistrationMethodBSpline#ImageRegistrationMethodBSpline.cxx" target="_blank">http://www.itk.org/Wiki/ITK/<u></u>Examples/Registration/<u></u>ImageRegistrationMethodBSpline<u></u>#<u></u>ImageRegistrationMethodBSpline<u></u>.cxx</a><br>
<br>
But I could not figure out why you subtract the SplineOrder from the meshSize in the itk4 version :<br>
<br>
unsigned int numberOfGridNodesInOneDimensio<u></u>n = 5;<br>
meshSize.Fill( numberOfGridNodesInOneDimensio<u></u>n - SplineOrder );<br>
<br>
I compiled your example with itkv3 / itkv4 and the only way I found to get the same number of parameters is by removing this subtraction. Is there something wrong on the wiki page or am I misunderstood something ?<br>
<br>

PS :<br>
It was a bit difficult to find your email address, so a bit before finding it I posted a bug in the itk bug tracker here : <a href="https://itk.icts.uiowa.edu/jira/browse/ITK-2671" target="_blank">https://itk.icts.uiowa.edu/<u></u>jira/browse/ITK-2671</a><br>
