could not find the lammps command to compute the residence autocorrelation function

Dear lammps users,
I am trying to reproduce the residence autocorrelation function results from the paper: pressure-driven supercritical CO2 transport through a silica nanochannel.
Here is the part related to the residence autocorrelation function in the paper.

I have searched the mailing list but still cannot find the right command or the method to compute the residence autocorrelation function in lammps.
I would really appreciate it if someone can give me a suggestion.

​look carefully in the paper for hints/explanations and consider contacting the authors. it is very likely, that this is not compute during an MD run, but with a custom code in post-processing.

Got it. Thanks for the suggestion!
