eeg_runica

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

Perform ICA decomposition using runica (infomax) algorithm.

When option_scaleicarms is enabled, components are scaled so each mixing column has RMS 1, matching EEGLAB eeg_checkset.

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.
