Seed used in GenIC

I would like to know if I could find the seed value originally used in GenIC for TNG300. I'm aware that I can download the initial conditions position and velocity, but I'm looking for the actual seed value inputted into GenIC. Thanks!

HI Adam,

The seeds are:

%Seed             5463      %  L75* (TNG100)
%Seed            8458657   % L35* (TNG50)
%Seed             2695896   % L205* (TNG300)

Although a modified version of N-GenIC was used to make the TNG ICs, I think it likely that the public version has the same noise field specifications, so that you should be able to make an IC with the same perturbations. Let me know!

I can verify for TNG300 that they do match. Thank you for finding this for me.
