[Eeglablist] Urgent help

Thanks a lot for your prompt reply and the useful link. However, I don't
have any events (markers) for participants' recorded data. I have only the
signal resulting from the task.
Here is the scenario:
For the sake of clarity (for now), I have:
a) 30 subjects
b) 2 conditions.
c) 10 visual task trials for each condition.
d) subjects only need to see the trials.
e) not button pressing-->no ERP analysis (analysis only based
"time-frequency" or "ERSP")
1- For first subject, how did you recommend saving the recorded data
(during the experiment) to be used later at preprocessing stage and STUDY
2- However, do you recommend *ALWAYS* using **only** one file to save the
data for each subject (all conditions) with both ERP and ERSP analysis?
