[Eeglablist] Variable length epoching

[arno delorme]

Dear Sharareh,

if you have 7 types of trials, then you will need 7 datasets to handle  
them in EEGLAB. If you are just interested in time-frequency  
decompositions, the newtimef function allows you to define portions of  
data of unequal length on the continuous data to contrast between 2  
conditions.

Hope this helps,

Arno
