[Mne_analysis] Setting the Marker channel

[Jaakko Leppakangas]

Hi,
it seems that the stim channel is assigned as EEG for some reason (probably
a mistake in the acquisition). Also the values on the stim channel are
micro scale causing the event finding to fail. Here's a short script for
fixing raw object.

import mne
raw = mne.io.read_raw_fif('to_share-raw.fif', preload=True)
data = raw.get_data()
data[14] *= 1000000
raw = mne.io.RawArray(data, raw.info)
raw.set_channel_types({'STI 014': 'stim'})
