[Eeglablist] How to keep urevent information even after epoching

[Antonio Schettino]

Hi Michele, Daniele, and Makoto,
this is Antonio, the author of the pipeline mentioned by Daniele. 
Unfortunately there must have been a misunderstanding: in that short 
workshop I aimed at showing one possible way to preprocess EEG data to a 
group of students with various skill levels, therefore I did not go into 
much detail. However, I hope that Michele could get some inspiration 
from those materials and be able to solve the problem.
Thanks again for your interest!

Greets,
