Directed transfer function (DTF) calculation for EEG data

I've acquired EEG data from 20 participants and I have 19 channels. I've calculated some functional connectivity methods between each pair of channels to obtain the connectivity between brain areas. Now I've been asked to implement a directed connectivity method (the directed transfer function) in order to obtain more information because by using a directed method I can also obtain the direction of the connectivity (that is, if the information flow is from channel x to y or from channel y to x). But I'm having trouble finding a matlab code to calculate the directed transfer function. How can I calculate this method in matlab?

The Wikipedia article on Brain connectivity estimators provides a llink to HERMES that apparently can be downloaded (I have no reason to download it so I have no experience with it). It is written in R2012a so it may need tweaking to work with subsequent versions. Contact the authors to see if there is a more recent version available, since MATLAB has changed significantly in the last 11 years.

Do a PubMed search to see if there are any others that may be more applicable to what you want to do.
