[Eeglablist] Dear list, about line noise.

Dear Makoto,

I see that you recommend in that paper a combined usage of ZapLine and CleanLine for optimal results. Although you specifically suggest the use of CleanLine after ZapLine, I was wondering whether the opposite makes any difference.


Thank you in advance for your help.

Kind regards,
Ramtin

Dear Hsin-An and Meha,

Here is the recently published comparison between CleanLine
(cleanLineNoise) and ZapLine.

I think CleanLine is good for general purposes if you need to retain the original signal in the line noise frequency range. The assumption here is that line noise has much slower time constant to modulate amplitude (i.e.
line-noise signal nvelope) than the genuine EEG signal. The same goal can be achieved by ZapLine if the spatial filter of the line noise is stationary, but this assumption is less likely.
