Hi Zhiwei Fan,
<div class=""><br class="">
</div>
<div class="">Averaging across a spectral band these days is done with the ft_selectdata function:</div>
<div class=""><br class="">
</div>
<div class="">cfg = [];</div>
<div class="">cfg.frequency = [low high]</div>
<div class="">cfg.avgoverfreq = ‘yes’;</div>
<div class="">dataout = ft_freqanalysis(cfg, datain);</div>
<div class=""><br class="">

<div class="">Good luck,</div>
