[Eeglablist] Filtering and ICA before Granger C analysis

[Eric HG]

Hi everyone,

Does anyone know what the optimal filters for Granger Causality? There
seems to be few different options for this. For line noise, would it be
optimal for using CleanLine?

Lastly, have anyone used ICA for removing eye movement artefact before
performing Granger Causality analysis?

So far, I have used the firfilt function for high-pass, cleanline for line
noise and no low-pass filter and no ICA for removing eye movement
artefacts.

Thanks a lot in advance!

Best regards,
