There was no file. You cab send it back channel.
The Mitsar while recording is measuring always, irrespective of the montage
the whole band up to 70 Hz, for the selected electrodes(so the physical
electrodes). After recording you cab play with different montages.
To check for 50Hz act. set the notch fil;eter on none and you should see not
too much 50 Hz.
If you have a lot of 30-40Hz activity(gamma) then there is a great
possibility that that is EMG.

If you send me the file backchannal I can look at it.
