<meta http-equiv="Content-Type" content="text/html; charset=utf-8"><div dir="ltr"><div>Dear Christine,</div><div><br></div><div>If you want to keep your 'unreferenced' or rather 'pre-rereferenced' channels, you could just add them from the state before re-referencing. Or preprocess a set of channels separately and concatinate them later. Note sure <i>why </i>you would like to do that though as you would be ending up with channels with different referencing schemes. In any case, per default you lose your reference channels, as they will (average to) zeros anyway. <br></div><div><br></div><div>Also see: <br></div><div></div><div><code>

<br>
I am asking myself (& the code, both without success) whether <br>
<br>
i) the new reference in ft_preprocessing is also applied to the original reference channels (which in the case of linked mastoids is not desirable) and if that is the case, ii) whether the code allows to only apply the new ref to specific channels only. Any ideas are appreciated!<br>
<br>
Best,<br>
