[Mne_analysis] Ocular artifact correction with 21 EEG channels (+ VEOG and HEOG)

[Servant Mathieu]

Hello,

In our lab, we usually reject epochs that are contaminated by any artifact.
I have a dataset where I would like to analyze the ERN (time-locked to the
response) . Problem: participants generally blink just right after the
response, and most of my epochs are contaminated by blinks. I am thus
looking for an efficient artifact correction method.
My dataset features 21 EEG channels [subset of the International 10/20
System sites: Fz,  Cz,  Pz,  F3,  F4,  C3,  C4,  P3,  P4,  PO3,  PO4,  T3,
 T4,  T5,  T6,  O1,  and  O2  and  the nonstandard sites OL (halfway
between O1 and T5) and OR (halfway between O2 and T6)] + VEOG (bipolar) and
HEOG (bipolar)]. Given this small number of electrodes, I don't think it is
appropriate to use ICA. Any suggestion?

Mathieu
