[Mne_analysis] on_missing and time-frequency

[Denis-Alexander Engemann]

Hi Virginie

1. this is in fact an issue with the documentation, not a bug. The 'ignore'
option will avoid crashes if one or many events are missing but at least
one remains. If all events are missing nothing will be ignored, currently
the constructor needs at east one event. We might want to rethink the
semantics. Out of curiosity, what are you doing with epochs for which you
know in advance that events and ids don't match? In other words, would
there be a use case for the behavior you expected from 'ignore'? If it's
just to avoid crashes when no event is found, I would manually check that
and skip computations if nothing is found. For example (in a loop that
iterates over datasets or subjects):

if not np.any(np.in1d(event_ids.values(), events[:, 2])):
    continue

2. the second issue sounds mysterious to me, I don't `smell` what might be
going on there.

So you imply that power = tfr_morlet completed (after 2 hours?) but that
`power` was not found?

This should not be necessay, this one is private and should be ignored for
regular usage.
