Hello Allen,<br><br>If i have understood what you meen that's
impossible. ICA makes different decomposition matricies for different
data...So there is no mean if the data are from the same person. It's
possible to perform ICA two times in a specific multichannel EEG and
get different result in the mean of the above example : <br>
<br>
x1 =[ a1 a2 a3][s1 s2 s3]^T= [a2 p*a1 a3][s2 s1/p s3]^T= a1s1+a2s2+a3s3<br><br>I
know extended-ICA which EEGLAB use as default is very slow procedure
but you have to run again and again the algorithm for different
datasets....you can try fast ICA<br>

<div> </div>
<div>I use ICA to reject EOG.But there are several EEG files generated
by one subject. </div>
<div>I want to apply the weight of ICA in one file to the others of one subject.
How could I realize it?</div>
<div>Thank you for any information!</div>
