It really doesnt make sense anymore. Everyone agreed?
Jan-Mathijs Schoffelen - 2011-10-03 13:17:50 +0200
why?
Stephen Whitmarsh - 2011-10-03 13:26:21 +0200
1) its an 'active' default, i.e. it does things you would not expect without you asking. 2) it does not make sense to demean before you do ICA for artifact removal where large differences in offset can be expected due to e.g. eyeblinks.

OK, let's discuss in the FT-meeting.

Either we have to discuss this still, or my memory has to be refreshed...

make FAQ "why demean before ICA"

(In reply to comment #5) I don't know immediately know the answer to this. Closing this bug and making a new bug about the FAQ.
