<p class="MsoNormal">Dear Fieldtrip community, <br>
<br>
I have a question with regards to the Z-transformed coherence, as explained in Schoffelen et al. (2005, 2011).<br>
In the articles, Z-spectra difference in coherence between a channel pair is calculated after computing the spectral decomposition with a multitaper method and the coherence between the channel pair.
<br>
I was wondering how the Z-transformed coherence can be calculated when spectral decomposition is computed using a Hanning taper instead.
<br>
Would it then only be necessary to compute the inverse hyperbolic tangent of the coherence value for each condition and then subtract these (i.e. atanh(coherence_condition1) – atanh(coherence_condition2))?<br>
<br>
Thank you in advance for any help with this question! <o:p></o:p></p>
