[Mne_analysis] Mne_analysis Digest, Vol 75, Issue 1

[Kambiz Tavabi]

Mauricio,
Did you set `eog=True` in the arguments to  `mne.fiff.pick_types` i.e.,

picks=mne.fiff.pick_types(info, meg=False, eeg=True, stim=False, eog=True,
exclude=[])

If the picks array is built without your channels of interest then
mne.Epochs will throw the error you're seeing c.f. epoching example (
http://martinos.org/mne/stable/auto_examples/plot_from_raw_to_multiple_epochs_to_evoked.html
).

best,
Kambiz
