[Audette, Michel]

Hi Claude, 

thanks for the tip but...

    yspace                    512     0.195312      93.2894
    xspace                    512    -0.195312      26.8047

My best recourse appears to be to opt for mincresample and figure out the new start point. 

maudette at icaw164201:~/data/data/work/goodEarData> mincresample -xstart -72.999732 -xstep 0.195312 -ystart 93.2894 -ystep 0.195312 etzold_emma_12792115_003002_mri_xyz_flt_2.mnc etzold_emma_12792115_003002_mri_+xyz_flt_2.mnc -clob

    yspace                    512     0.195312      93.2894
    zspace                    129     0.299075     -67.2154

Sorry for the trouble. This bug is really odd, though. 

Cheers,

Michel
