It appears there may be a deeper issue with how the b-spline is defined over the upper range of the last index. The transform should be valid from (minIdx-0.5, maxIdx+0.5). I am going to also note that this case is not in itkBSPlineDeformableTransform.</div><div class=""><br class=""></div><div class="">Brad</div><div class=""><br class=""></div><div class="">[1] <a href="https://github.com/InsightSoftwareConsortium/ITK/blob/master/Modules/Core/Transform/include/itkBSplineTransform.hxx#L465-L495" class="">https://github.com/InsightSoftwareConsortium/ITK/blob/master/Modules/Core/Transform/include/itkBSplineTransform.hxx#L465-L495</a></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""><div><blockquote type="cite" class=""><div class="">On Apr 20, 2016, at 7:07 AM, Denis Shamonin <<a href="mailto:dshamoni@gmail.com" class="">dshamoni@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><meta http-equiv="Content-Type" content="text/html; charset=utf-8" class=""><div dir="ltr" class="">Dear Developers,<br class=""><br class="">We have found the rare but reproducible crash during the resampling in combination with BSplineTransform.
