Hi,<br><br>This is probably a stupid question: How come whenever I try to do a simple rigid registration with really basic images that created using Microsoft Paint I never get the right outputs? The output images are always intensity inverted (black becomes white and white becomes black), and the registration never seems to have taken place (the output image seems to be the moving image all the time, but intensity inverted).
<br><br><br>Thank you very much,<br>Kevin<br>
