[Eeglablist] Similar ICA components

Is the data in the "time.png" (of the folder that you sent) component data?
If yes, then I see that component 3 and 4 are quite noisy. Was the data
cleaned (hand-cleaned, line-cleaned) before it was fed to the ICA? If all
precautions taken at the start of ICA, I would rather reject these ICs 3
and 4 (of course it also depends on the expt aims).
So, to your answer, not so sure where they coming from, but sure they look
quite noisy and artifactual.
