Hi @NGillet , thanks for the report. Can you copy/paste this to https://github.com/21cmFAST/21CMMC/issues/new ?
@NGillet , the default flag_options struct has USE_MASS_DEPENDENT_ZETA set to False. This should be set to True if you are using F_STAR and F_ESC.
Hi,
I am trying to do a likelihood_NeutralFraction MCMC : 1) CoreLightConeModule
2) likelihood
3) MCMC:
The problem is that the return lnL is always 0. I looked at the core and likelihood module and found that the actual modeled neutral fraction is identical between walkers and iterations:
In CoreLightConeModule I print the params (they do change as expected), but after the computation of the lightcone
lightcone.global_xHI
is always the same !I am stuck here, I do not know why because the actual input params are different and should change the resulting xHI.
I try to switch of
regenerate=False
or to put the random_seed generator. I get a warning for the first and I am not sure the second work too.
