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

[Arnaud Delorme]

A 2-second epoch length is recommended

https://urldefense.com/v3/__https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10374983/__;!!Mih3wA!HzkOG00AiNwDWffh55jUD2d7vRJ13i5ZuKJgRueE6YaMO8pUxNbtaX0udVbSQOB3HC5btZYlIIrjcpkmfMSOTKAf$ 

The advantage of the 2-second epoch length is that it gives you a frequency resolution of 0.5 Hz instead of 1 Hz if you use 1 second.
Best wishes,

Arno
