[FieldTrip] Renormalized PDC

I am working on a connectivity analysis (partial directed coherence) in
I found this paper by Schelter, B.; Timmer, J.; Eichler, M. (2009).
"Assesssing the strength of directed influences among neural signals
using renormalized partial directed coherence"./J. Neurosci
Methods/*179*(1): who suggest to rather use a renormalized PDC.
Has anybody here used this before and could tell me how to calculate
this rPDC in Fieldtrip?
All the best,
