[MINC-development] reversedef?

[Vladimir S. FONOV]

Hello,

I suppose these days one can achieve this by doing

1. xfm_normalize.pl xfm.xfm temp.xfm --invert --exact --like template.mnc

2. mincresample -transform temp.xfm -invert_transformation input.mnc 
output.mnc -like template.mnc

however, I didn't make experiments to see how much faster it will be
