<div dir="ltr">Thanks for the reply, Alex!<div><br></div><div>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. </div><div><br></div><div>Is this something a work in progress? </div><div><br></div><div>Thanks again!</div><div><br></div><div>Le</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Dec 12, 2014 at 5:05 PM, Alexandre Gramfort <span dir="ltr"><<a href="mailto:alexandre.gramfort@telecom-paristech.fr" target="_blank">alexandre.gramfort@telecom-paristech.fr</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">hi,<br>
