<span style>Hello, I would like to ask you what does the "cfg.frequency" means in ft_sourceanalysis. I want to plot a frequency range for example [14 30], do i have to use cfg.frequency=22? why? It would be perfect if someone could explain how to make the freqanalysis and the sourceanalysis for a frequency range for example this one[14 30]. </span><div>

<div>source_post11= ft_sourceanalysis(cfg, freq_post);</div><div><br></div><div><br></div><div>What i get i see that depends only in the cfg.frequency=22, if i change the previous freqanalysis and use the 22 for the cfg.frequency i get the same result. Hope someone can help me.</div>
