[Mne_analysis] derived channel in python

[Le Wang]

Thanks for the reply, Alex!

The post in your link seems to be talking about re-referencing, which is
also a nice feature to include. But what I was thinking about was to take
the difference between a pair of channels (to get the saccade signal, for
example)  and do some further processing (ie., saccade detection) with the
derived signal. I guess I can always do that using a separate numpy array,
but it seems more elegant to be able to save the derived signal in the raw
object as a derived channel.

Is this something a work in progress?

Thanks again!

Le
