[Eeglablist] Resting state EEG: 1-sec vs 2-sec non-overlapping epochs

[Cedric Cannard]

Hi,

Depends on the frequency bin and resolution you need. e.g. for 1 hz, you’d want probably 4-s windows to capture the cycles. Otherwise, 2 or 4-second windows are commonly used. If I remember correctly, roiconnect segments into 2-s epochs so that might be your best choice here.
