[Eeglablist] EEGlab Import events on loop - error

[Makoto Miyakoshi]

Dear Bruno,

If I understood your question correctly...
The variable ALLEEG is one of the structures automatically generated by
calling 'eeglab'. After calling 'eeglab', ALLEEG = []. It is actually the
same as running ' ALLEEG = []' then run your code. Please try it to see if
it works.
