[Eeglablist] (ask) about averaging and ICA

[Bagas Isadewa]

hello,

i have several questions, 

1. if I wanted to average EEG data to yields good ERP, how many minimum trials 
do I needed ? is there any paper or journals that explained about it ?
2. then, if I wanted to run ICA to extract ERP, do I need many trials or only 
single-trials in one epoch will be enough ??
3. is it necessary to run ICA first then do averaging or it is enough to use 
only one technique for extracting ERP ?

if you don't mind please give me an explanation
thank you very much


regards,
bagas isadewa
