Hi Rob,

from iotbx import mtz
mtz_obj = mtz.object(file_name="file_name.mtz")
miller_arrays = mtz_obj.as_miller_arrays()
for miller_array in miller_arrays:
   miller_array_truncated = miller_array.resolution_filter(d_min=2, d_max=5)

For more use example have a look at cctbx_project/iotbx/mtz/tst.py and 
as always "print dir(miller_array)" is your friend!

Hope this helps!
