Once with cfg.frequency = [4 7]; cfg.avgoverfreq = ‘yes’; and accordingly for your other freq band of interest.</div><div>best</div><div>tzvetan</div><div><br><br class="Apple-interchange-newline"><blockquote type="cite"><div dir="ltr">hey Brittany, I am far from being a fieldtrip profi, but as far as I can get you can either use
<p class="">ft_freqgrandaverage and average over frequencies (cfg.parameter='freg'), or you precise cfg.avgoverfreq = <span class="">'yes' in the </span> ft_freqstatistics. Of course you could also change the steps of ft_freqanalysis to bigger steps...
