Hello all mne\_analysis

I try to reject ECG artifact in EEG using MNE library  
(ref URL :  
[https://martinos.org/mne/stable/auto\_tutorials/plot\_artifacts\_correction\_ica.html?highlight=ecg](https://martinos.org/mne/stable/auto_tutorials/plot_artifacts_correction_ica.html?highlight=ecg)  
)

first, I decompose EEG signal to independent components

and set some parameters(n\_components, method, decim, random\_state) for ICA

Do you guys know how to set parameter or any reference for ICA parameter?

I use ICA parameter like:

n\_components = (half of channels)  
method = 'fastica'  
decim = 3 (just follow artifact correction manuel above)  
random\_state = (half of channels)

and my uasge using ICA paramter above:  
ica = ICA(n\_components=n\_components, method=method,  
random\_state=random\_state)  
ica.fit(raw, picks=picks\_eeg, decim=decim)

do you guys have any know-how?

Thanks

hi,

unfortunately I can only personally advise you to look at the components  
and assess if you correctly capture artifacts with the parameters you used.

Best,  
Alex
