[Eeglablist] Create STUDY one set file per participant containing all conditions

Dear Komono,

Sorry for belated response. Thank you also for the screenshots. Very easy
to understand.
I have never specified 'condition' in creating STUDY. It does not make
sense if you have multiple conditions, isn't it? So leave 'condition'
empty. STUDY.design can specify the factorial design using the multiple
conditions correctly.

The tutorial is old and may not be updated... that's my impression.
Originally, to make a STUDY, one .set files per condition was the rule.
However, after implementing STUDY.design, this was changed. So if you don't
see description about STUDY.design in the manual, it's just old.

Makoto
