Dear Blake, Are you using the -2D option with the -applyxfm and -init? It is necessary in order for it to appropriately interpolate correctly. However, it does assume that the image is in the xy-plane. If this is not the case then it will require some special options.

Is this possible? I tried -init mat.mat -applyxfm and didn't work (the entire image was the same value). I also tried the GUI with the same result. > > > Thanks, > Blake Dewey > Vanderbilt University Institute of Imaging Science >
