Yes, of course! I hope they are small enough.
Anyway, if I use the NC, I get this:
Traceback (most recent call last):
File "qmmm_sander.py", line 22, in <module>
with sander.setup(parm, parm.coordinates, parm.box, inp, qm_inp):
File "/home/elisa/amber16/lib/python2.7/site-packages/sander/__init__.py",
line 268, in __init__
box = _np.array([float(x) for x in box])
TypeError: only length-1 arrays can be converted to Python scalars
