<br>Thank you. I see also what is the cause...<br><br>Is there a way to avoid setting the defaultFixelValue to 100 and set it in a way to complete the moving image (e.g. complete the image using the old values of the moving image or some interpolated version of that). I really do not have clear if this would be appropriate but I would like not to have empty/flat spaces in my registered image because they make my slices unusable for analysis.<br>
<br>I hope I explained me clear.<br><br>Thx<br><br><div class="gmail_quote">2010/9/28 Navneeth Subramanian <span dir="ltr"><<a href="mailto:navneeth.s@gmail.com">navneeth.s@gmail.com</a>></span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
The cause is seen in line 600:<br>resampler->SetDefaultPixelValue( 100 );<br><br>This is the value being applied during the interpolation of the moving image based on the computed transform.<br>Change it & you're all set.<br>

Yes, exactly the last slice of the registered image.<br><br>Is there anyway to limit this effect?<br><br>What if one adds empty slices on the lowest (highest) border? does that affect the registration?<br><br>Thx <br><br>

By last image, did you mean the last slice of the registered (moving) image?<br>
<br>
If so, I think this is because of the image transform applied that<br>
moves the image totally out of that image plane. It will happen to the<br>
boundary slices usually.<br>
