<span id="ms-outlook-ios-cursor"></span>Thanks Jan will do. Can I ask if the specification of avgoverfrequency actually averages powspctrm values in all frequency bins if foi is [2 6] or looks at only 4hz the average of 2+6/2. The output says 1 frequency bin
and stat.freq shows 4 in output when aevraging is done meaning does it only look at 4Hz frequency?</div>

<div class="">The output data object is quite extensively described.</div>
<div class=""><br class="">
</div>
<div class="">@3: the error message is quite clear I think, so the answer would be ’no’, unless you squeeze out either the frequency or time dimension. This can be done with ft_selectdata, and an appropriate specification of the input cfg. Please refer to the
function’s help to get you on the way.</div>
