[Eeglablist] epochs of resting conditions

You can add event markers post-hoc. Check 'Edit' - 'Event values'.

ICA does not require epochs so don't worry.

If you want to generate 2 second long epochs, the work around with GUI
would be found again in 'Edit' - 'Event values'. It would be much more
efficient if you can code a simple loop to do this job. Try 'eegh'
after you use GUI to see if it is interesting for you.
