events not listed in raw object, and unable to add_events, but can find_edf_events

See original GitHub issue

I have a raw edf data object, which appears to have no events:

In [1]: data = mne.io.read_raw_edf("data.edf",verbose=True,preload=True)
In [1]: data.info['events']
Out[1]: []

even if I try adding some:

In [2]: events = np.array([np.arange(0,100000,1000),np.zeros(100),[1]*100]).transpose()
In [2]: data.add_events(events)
In [2]: data.info['events']
Out[2]: []

However, the data has some events in the header:

In [3]: data.find_edf_events()
Out[3]:
[[35.558594, 2.621094, 'test block'],
 [182.128906, 0, 'Pause -  0:03:03'],

Is this a bug? What’s going on?

no idea either…

the edf IO should be simplified with Annotations. Cf comments from 2 weeks ago

Closing this as something we won’t fix as it could cause backward compat problems, and in our Info docs we now say “…In general this should not be used…”.
