Dear Zahra,
<div class=""><br class="">
</div>
<div class="">Again, I would like to stress that you need to read the documentation in the code, the code itself and the documentation on the website.</div>
<div class="">Also, I would like to stress that (although I am one of the usual suspects that takes the time to reply to questions on this list), I am not running the list, so everybody is explicitly invited to chime in here. This is not only a nudge to everybody
who is reading along, but also a gentle nudge that I’d appreciate not to directly direct e-mails on this list to me in person, unless you have realistic expectations that I am really the only one who can provide an answer.</div>
<div class=""><br class="">
</div>
<div class="">Best wishes,</div>
<div class="">Jan-Mathijs</div>

<div class="">Dear Jan-Mathijs;</div>
<div class=""><br class="">
</div>
<div class="">I am sorry for troubling. Is it possible to use ft_connectivityanalysis with a "data" input which is not an output of the ft_preprocessing function?</div>
<div class="">Indeed I have an EEG time series in 16 channels. Filtering and denoising has been applied on it. Would you please tell me how to use this signal?</div>
<div class="">Thanks again.</div>

<div class="">Please use ft_connectivityanalysis with cfg.method = ‘wpli’, and an appropriate fieldtrip-style data structure, containing fourier coefficients (i.e. output of ft_freqanalysis with cfg.output = ‘fourier’);</div>
