Strange PLV results

External Email - Use Caution

Hi all,

I got my phase locing values with codes like these:

fmin, fmax = 3., 30.
sfreq = epochs.info['sfreq']
tmin = 0.0
tmax = 1.0
con, freqs, times, _, _ = spectral_connectivity(
    epochs, method='plv', mode='multitaper', sfreq=sfreq, fmin=fmin, fmax=fmax,
    faverage=False, tmin=tmin, tmax=tmax, mt_adaptive=True, n_jobs=1)

Then I got the 'con' result with most of zeros. I wonder there is something wrong with my script.

Thanks for any help!

Best regards,
Yuri

hi,

you should use plt.matshow to look at this matrix.

if you have zeros it's because I think we do not compute
full matrices when we know it's symmetric.
We only compute the lower triangular part.
