[Eeglablist] epochs needed for ICA analysis

[Arnaud Delorme]

Dear Tara,

> With that in mind, does anyone have any thoughts about how many epochs are needed for reliable individual ICAs for cognitive potentials, assuming I have clean data?  For instance, would 500 epochs per individual be enough?  Any thoughts would be appreciated.

It depends on the number of sampling point you enter into the algorithms 
and the number of channels you have. Here are some messages on this 
topic by Stefan and me.
