[Eeglablist] can eeglab calculate the phase-locking value?

[Zachary Moran]

Hello,

The default EEGLAB setting for the current ITC function is set for "phase
coherence" (i.e., the script reads 'type', 'phasecoher') which should be
equivalent to what was initially referred to as "phase-locking factor".
While I'm not positive that this is the same as phase-locking value, my
guess would be that it is.

Hope this helps!
