[MINC-users] ensuring that mincreshape produces positive axes

[Andrew Janke]

Take a look at man mincreshape, there is a "extra thing" that you have
to do to force mincreshape to flip the slice dimension.

This will always work (and also make everything zyx ordered.

      mincreshape \
      +direction \
      -dimorder zspace,yspace,xspace \
      -dimsize xspace=-1 \
      -dimsize yspace=-1 \
      -dimsize zspace=-1 \
      in.mnc out.mnc
