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

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

I’m sorry, I can’t read the .set files you uploaded.  It looks like you renamed the files?  .set files don't let you do that.  Could you send me the files with the original names?

In the former, it barely made any noticeable difference while in the latter it did change the grand average waveform. I am not sure why it did not work on the nose-referenced data. Is it actually okay to apply PARE referencing to a data set that has already been referenced to the average of the scalp electrodes?

>> 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.
