[Mne_analysis] Problem with microvolts scaling

[Jaakko Leppäkangas]

Hi Emanuela,

looks like the data in the evoked instance is in microvolts instead of
volts. Did you use EpochsArray to read the data in? If so, the data should
be scaled to volts before reading. But I think you can just do something
like: evoked.data = evoked.data * 1e-6 and then save the data again with
evoked.save.
