On this note, you might find this useful:

ie:

   $ volextents in1.mnc in2.mnc ...
   -xstart -118.1785899999999998 -ystart -126 -zstart
-137.15181999999998652 -xstep 1 -ystep 1 -zstep 1
   -xnelements 241 -ynelements 314 -znelements 273

The idea is that it gives you the minimum bounding box (with default
direction cosines) to enclose all of your volumes.  The output is in
"mincresample" friendly format.

harold:me$ volextents -help
| volextents figures out the extents of a bunch of input MINC files
|
| The output is in a form that can be used by mincresample
|    the calculated extents will start from the foremost
|    voxel of the foremost volume and extent to the number
|    of voxels required to cover the entire volume(s). This
|    will mean that volextents will often produce extents that
|    will extend beyond the required volume due to the step
|    size that is chosen. There is only one way around this
|    and that would be to instead centre the output sampling
|    around the input volumes. This has not yet been
|    implemented as I dont need it yet!  Feel free to whinge
|    if you want it and I might just add it if vast quantites
|    of chocolate are sent.

Summary of options:

-- General Options -------------------------------------------------------------
   -version  print version and exit
   -verbose  be verbose
   -noverbos opposite of -verbose [default]

-- Extents Options -------------------------------------------------------------
   -step <float>
             the step size of the output dimensions [default: 1]
   -int      round the start position to an integer
   -noint    opposite of -int [default]
