Re: [Erppcatoolkit-support] Using PARE correction for EEG data

[Joseph D. <jd...@ma...>]

Thanks!  You do not need to re-reference first.  The PARE option is just a modified average-reference procedure (referenced to the average of the full interpolated head rather than just the average of the electrode locations).  Use the “re-reference” option in the Topomaps view to get a sense of what it is doing.

Cheers!

Joe
