<div dir="ltr"><div><div><div><div><div><div>Hi,<br></div>thanks for a wonderful toolbox!<br><br></div>I will try to use ICA to remove blinks / eye-movement / ECG artifacts, but i have some questions i would be very happy if someone could address:<br>
<br></div>1. For the ICA decomposition, does it matter if the electrode locations are correct? That is, would the decomposition work even if the locations would be completely randomized? I ask because i dont know where to place the eye / ecg electrodes exactly.<br>
<br></div>2. Is it a good idea to always include the eye / ecg channels in the ICA decomposition? I ask because i thought to decompose data based on scalp electrodes only and then verify blink / pulse components by comparing them to the eye / ecg channels. When should i not include the eye / ecg channels in the ICA decomposition?<br>
<br></div>Thanks for your time and your responses!<br><br></div>Kris<br></div>
