<div dir="ltr"><div><div><div>Hi all<br><br></div>I imported an EEG signal with 7
epochs to EEGLAB and i applied ICA to remove some artifacts. Now i can
plot ICA component activation (time courses) using plot>component activations. But i can't find
the variable or matrix in workspace related to ICA component activation. I know that I can find ICA component using EEG.icawinv matrix in workspace. <br><br></div><div>It means if the ICA decomposition equals: <br><br></div>
<div>U=WX<br><br>where X (EEG channel recordings) and U (ICA component activations) are n *t matrices (n channels (rows) by t time points (columns)), and W (ICA weights (EEG.icawinv )) is n* n. I want to know how i can have matrix of U in EEGLAB?<br>
