[Eeglablist] imported BrainVision data: finding the reference electrode

[Stephen Politzer-Ahles]

Hi Ricardo,

May I ask what your reference was? In my experience using Brain Vision
data, the recording reference (in my case it was on the nose) was just not
included in the data that I imported to EEGLAB. This wasn't a problem for
me because I wasn't interested in analyzing that electrode anyway after I
re-referenced; but it might matter for you if your reference is something
that you care about as an active electrode, like Cz. You may be able to get
that channel back by using the "Add current reference channel back into the
data" command and specifying its location (but I haven't tried that myself
with BV).

Best,
Steve
