[Mne_analysis] Phase Lag Index connectivity using single epoch

[dae kook do]

Dear everyone,

I have a problem about PLI.

I saw a paper(Phase lag index: Assessment of functional connectivity from
multi channel EEG and MEG with diminished bias from common sources (Hum
Brain Mapp 2007)
) about PLI in MNE example (Compute all-to-all connectivity in sensor space)

In this paper, PLI is checked by each montages (Figure 6, Influence of
reference)

When I read that, I think Figure 6 is calculated by each epochs.

I tried to calculate PLI using spectral_connectivity with single epoch.

But, results just return same value "1".

How to calculate PLI using single epoch?

Or is Figure 6 calculated by several epochs?

I add my result.
