Hi Tibor,
<div class=""><br class="">
</div>
<div class="">Some of this is discussed (and fixed, there were some small issues in the code) in <a href="https://github.com/fieldtrip/fieldtrip/issues/1454" class="">https://github.com/fieldtrip/fieldtrip/issues/1454</a> and the PR that is linked in the linked
issue.</div>
<div class=""><br class="">
</div>
<div class="">Note: if you want to go from sensor-level to source-level data in the frequency domain, you should either use ‘powandcsd’, or ‘fourier’ as cfg.output argument to ft_freqanalysis.</div>
<div class=""><br class="">
</div>
<div class="">Best wishes,</div>
<div class="">Jan-Mathijs</div>
