Open binary data in python

Question

I want to read from a binary data file, in the old matlab version of my script this is done by

file=fread(data,'bit16');

which would be the equivalent thing in python ? i tried

with open file(data, "rb") as f:
    d = np.fromfile(f, "<i2", count = 10000)

since the matlab documentation says that bitn is of the type signed integer with n bits

i tried different dtypes ( "<>i2", "int16") unfortunately this doesnt give me the rigth data.

Just for whatever it's worth, np.fromfile('test.dat', np.int16) properly recovers data written from matlab with fwrite(fid, data, 'bit16') on my system. — Joe Kington

You may try to use float16 data type associated with numpy.frombuffer that deals with the half precision floting point (bit16 in matlab). The type doc is here.
