<div dir="ltr"><div>Hi,<br>I have received your data and run the attached test. I also get the error<br>"Description: itk::ERROR: Cannot account for too large detector displacements, a part of space must be covered by all projections."<br>wtih rtkfdk. Did you use rtkfdk for testing FDK? Your email suggested that it worked for FDK but it doesn't work for me...<br>Given your geometry, this is the expected behavior. If you still want to try the iterative reconstruction, you'll have to shunt the displaced detector filter in the pipelines using the documentation, see for example <a href="http://www.openrtk.org/Doxygen/dot_inline_dotgraph_20.png">this image</a> for sart.<br>Simon<br><br></div>PS: maybe we will consider changing the error to a simple warning and doing nothing in such cases, I'll discuss it with the local iterative pope<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Jun 10, 2015 at 1:40 PM, Simon Rit <span dir="ltr"><<a href="mailto:simon.rit@creatis.insa-lyon.fr" target="_blank">simon.rit@creatis.insa-lyon.fr</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div><div><div>Hi,<br></div>Can you send the mhd header and the geometry file to reproduce the bug?
