[Eeglablist] Power in reference interval of ERSP

[Clemens Brunner]

When I calculate ERSP maps with timef, how can I find out the power in the 
reference interval? I thought that this was the parameter mbase, but the 
values do not match the power values as calculated by simply filtering the 
signal in the desired frequency band, squaring and averaging in the reference 
interval.

For example, I manually calculate the power and get a value of 0.1824. The 
function timef yields a much higher value though, namely 1789.1. Is it 
possible to find out the reference power in a specific frequency band 
somehow?

TIA
