Hello, another Mitsar question. I have just examined the tabulated output of a file and noticed that for theta at cz the power was 58 and the hz was 7.58. 1. am i right in thinking that this means the peak frequency within the band range of 4-8hz was at 7.58hz? I ask this because when i look at the alpha power for the same location, ie cz, the alpha power is about 12 and the hz is 7.8. 2. This is odd, as the band range for alpha is 8-12hz, so how can the peak frequency be outside of the specified band range? or does the HZ refer to something else, and if so what? david
