[Eeglablist] Matrix of ICA component activations (time courses)

[omid abbasi]

Hi all

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.

It means if the ICA decomposition equals:

U=WX

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?


Best Wishes
Omid
