<div dir="ltr" class="">Dear M.J Schoffelen,
<div class=""><br class="">
</div>
<div class="">I am a phd student of the Brain Imaging Center of Frankfurt am Main. I usually take your work on spectral Granger Causality, as reference.</div>
<div class="">I have few short questions on nonparametric GC that I hope you can answer.</div>
<div class=""><br class="">
</div>
<div class="">1) The nonparamteric GC needs the full spectrum decomposition 0 Hz up to Nyquist frequency, is what you usually do ?</div>
<div class=""><br class="">
</div>
<div class="">2) I set the Fieldtrip function to granger.conditional='yes' , the output is source-->target conditional on all other sources of the network?</div>
<div class=""><br class="">
</div>
<div class="">3) I saw that you do the spectral analysis on channels and then project them to source space (multiply with spatial filter) does it make a difference to do the spectral analysis directly on virtual channel data?</div>
<div class=""><br class="">
</div>
<div class="">4) Padding. Would you suggest to pad the data? I have 0.250 ms task length, now I pad the data to 0.400 ms with a spectral resolution of 2.5 Hz and being interested on beta frequencies I use Hanning taper.</div>
<div class=""><br class="">
</div>
<div class="">thanks a lot for your help</div>
<div class="">Best,</div>
<div class="">Edoardo</div>
