Cz : 0 * Fp1
This would assume that I am creating a new electrode substituting Fp1 for Cz.
The way the data acquisition was set up, Cz was used as an offline reference, which suggests that the Cz electrode does exist. I would like to retain the Cz electrode if possible. If that is not possible, I would have no choice but to recreate this information by averaging across the adjacent electrodes.
E.g. Cz : 0.5 * Fz, 0.5 * Pz
What would you recommend?
