<br class="">
is it correct to fit dipoles (via DIPFIT2-plugin) to ICs that have been found including EOG channel in the ICA decomposition (as Arno suggested in <a href="https://sccn.ucsd.edu/pipermail/eeglablist/2007/001801.html" rel="noreferrer" target="_blank" class="">https://sccn.ucsd.edu/pipermai<wbr class="">l/eeglablist/2007/001801.html</a>)<wbr class="">?<br class="">
<br class="">
From my datasets I removed ICs where EOG channel contributes for >90% of IC power (considering them artifactual ICs), but how to deal with ICs where EOG contributes for example for 20%, or 40%, or 60%?<br class="">
<br class="">
Thanks,<br class="">
