cmtk unwarp_image_phantom --final-cp-spacing 40 --levels 2 phantom.nii  phantom.xml  unwarp.xform


Boy, I was really paying attention when I wrote that paper, didn't I? ;)

Thanks - I'll fix that too.
btw, a separate question, what would cause

snr: inf
cnr: nan nan nan inf

at the beginning of the phantom.xml file

Best guess - the SNR and CNR spheres were not found. In that case, the entire phantom detection is not valid.

Would you mind sending me the image file that produces this result? That would be the most efficient way for me to track down what exactly is going on.

In general (and I hope this is mentioned in the IJ paper at least) the phantom detection is still a bit work in progress, so things like sanity checks may still be lacking somewhat.

Best,
