Indeed there is. mincconcat in general will only work if you are
concat'ing on the slowest varying dimension of a file. Thus before you
concat do this:

   mincreshape -dimorder xspace,yspace,zspace A.mnc A_res.mnc
   mincreshape -dimorder xspace,yspace,zspace B.mnc B_res.mnc

At which point:

   mincconcat -concat_dimension xspace A_res.mnc B_res.mnc C.mnc

Should get you what you are after.
