I am learning to use cactus code and einstein toolkit to make compact object simulations.

I want to make binary neutron simulation like https://einsteintoolkit.org/gallery/bns/index.html

I have a question. How can i reproduce initial data file (e.g G2_I12vs12_D4R33T21_45km.resu https://einsteintoolkit.org/gallery/bns/G2_I12vs12_D4R33T21_45km.resu.xz) for a new neutron star parameters with LORENE code? I couldn't find enough information about this.

Best regards...
