Hi Vijay,
<div class=""><br class="">
<div class="">The best way to get started is to use the higher level function ft_connectivityanalysis, with cfg.method = ‘ppc’. Note that the data matrix needs to have an observation/trial dimension, so just a single 1xnfreq channel-pair csd will not fly. I
suggest to search the documentation of <a href="http://fieldtriptoolbox.org" class="">
fieldtriptoolbox.org</a> to get more information</div>

<div class="">Best wishes,</div>

<div style="margin-top: 0px; margin-bottom: 0px;" class="">I'm trying to use the ft_connectivity_ppc.m function to calculate the PPC between two channels of EEG. The shape of the input_matrix is defined as Repetitions X channel X channel. If I'm inputting the
CSD between two channels, It will be a one dimensional vector instead of two dimensions, and this doesn't satisfy the input_matrix requirements.<span class="Apple-converted-space"> </span><br class="">

Am I missing something here? Any help is appreciated.</div>
