[FieldTrip] Pairwise Phase Conistency (PPC) in 2 channel EEG

[Vijay Sadashivaiah]

Hello,


I apologize for this novice question - I'm pretty new to working with EEG signals.


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.


Am I missing something here? Any help is appreciated.


Thanking you, I remain,
Vijay Sadashivaiah
