[Mne_analysis] 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
