Subject: [Eeglablist] Re-referencing problem

Hi,

I'm currently using the latest version of eeglab and I'm having trouble adding Cz back to my dataset. I manually set it as the reference electrode, complete with coordinates, as suggested by the eeglab tutorial. However, while the program correctly states Cz as a reference, when I try to compute the average reference and add Cz back to the data, I get a warning saying that no reference channel was found and that I should add it with the channel locations editor.
Also, my interface is not the same as the one I find on the tutorial: I have no "Add current reference back" but "Add OLD reference back":

When I click on Add old ref. channel, I just get the warning, with no channels to select.

This is the screenshot that shows the reference correctly set to Cz:

Is there a workaround for this? I also tried to interpolate Cz, but it simply won't show up, so I can't reconstruct it that way either.
Any help would be greatly appreciated.
Thanks!

Francesca
