How did you obtain this? It is probably a function of cosmology, right? Do you expect this to be also a function of box resolution?

It would be great if @Laura-Casas tried to run LyaCoLoRe on a 2LPT box herself using the instructions, to validate them.

@mruizherrerab - it would be also great if you could add instructions about how to setup a future suite of sims if we changed the input cosmology or the box size / resolution. It is probably not easy to have automated scripts, I believe you had to do several steps by hand, right? But at least document well the steps to create the files that you added here (like the cell fraction for DLAs).
