~Apparently your signal became a Signal2D at some point, which doesn't have that class method? From notebook 1 it seems that you must use dp.set_signal_type("electron_diffraction")? I guess more active pyxem users can give you the answer if this doesn't work.~

Edit: see @pc494 answer below.

Hi there,

In the short term these can be fixed by add the line

data = pxm.ElectronDiffraction2D(data)

after loading. The 0.12 series (which I presume you are running) has some issues with io that should be fixed in our next release.
