  Dear Zhipeng,
       Thank you for your interest in our work. We developed the CFD method
based on PSI a few years ago, but it is not implemented and integrated in
Fieldtrip yet.  Nevertheless,  I made the code publicly available on my
github now (
https://github.com/HaitengJiang/Cross-frequency-directionality-CFD-). If
you have any questions, feel free to drop me an email.
                                                      Best regards,
                                                      Haiteng
