[Eeglablist] Extract AMICA Output

[Makoto Miyakoshi]

Dear Franzi,

sphere that would normally have been saved as output of the runamica15

Yes.

There is a potential technical issue there. If you learn about it, please
read this article.

If you do not understand what it means, save the data after ICA, then load
it, then continue to process the data.
