When I call connectivityanalysis on a 2 by 2 square matrix, I get the error: ??? Index exceeds matrix dimensions. Error in ==> ft_connectivityanalysis>coupling_psi at 524 p1 = abs(reshape(input(j,cfg.powindx(:,1),:,:,:), siz(2:end))); Error in ==> ft_connectivityanalysis at 321 [datout, varout, nrpt, phasediff] = coupling_psi(tmpcfg, data.(inparam), hasrpt, hasjack); Error in ==> FEF_par at 199 tmpIn = ft_connectivityanalysis(psi_cfg,tmpInfreq);

This is for the PSI calculation. Function works for coherence and granger.

Could you be a bit more specific about the exact input to the main function? Generally, you don't call it with a '2 by 2 square matrix' but with a freq-structure containing fourierspctrm? or crsspctrm?
