eegprep.eeg_runica

eegprep.eeg_runica(EEG, posact='off', sortcomps='off', **kwargs)

Perform ICA decomposition using runica (infomax) algorithm.

Parameters

EEGdict

EEGLAB-like data structure.

posactstr | bool, optional

If ‘on’ or True, normalize component signs so max(abs(activations)) is positive. Default is ‘off’.

sortcompsstr | bool, optional

If ‘on’ or True, sort components by descending activation variance. Default is ‘off’.

kwargsdict

Additional keyword arguments to pass to the runica algorithm.

Returns

dict

The updated EEG structure with ICA fields.
