[FieldTrip] Negative values of debiased wPLI

Dear Community,I am using the debiased wPLI to estimate connectivity between 70 EEG electrodes. I have about 150 trials for each subject. I noticed that some values of my 70x70 dwPLI matrix are negative. My understanding is that all values should be between 0 and 1, but for some reason I can get negative values from the debiasing process. My question is: Shall I calculate the absolute value of these negative values? Otherwise what shall I do with them?
Thank you in advance for your help.Marta
