How to convert s2p parameters to s4p parameters in a 4 port device using ADS?

Somehow I remember a setup in an @DS example that allows you to input s2p parameters for a 4 port device and it calculates the s4p parameters. I can't seem to find it. Does anyone know where it is?
tnx

Not quite. I measure the two port parameter files of a four port device (s12,s13,s14,s23,s24,s34). Then I want to convert them to a s4p files so I can use it like your diagram.

I saw this setup within one of the example projects but can't find it now that I need it. I do the conversion in Excel but would like to eliminate that step and do it directly in @DS.

I have the same problem, Do you know how to convert s2p measurements to s4p file?
Cheers

I want to convert a s4p touchstone file to a s2p one. any one can guide me about this?
