COSMOMC : chain don''t start

Post by Pierre Delsart » May 20 2009

Hello everyone,
I succeed to add at cosmoMC my own module. I check all the variables in the differents files params_CMB.f90, setting.f90...
I added 3 parameters but only one is free. I launched the process but the program called 1000 times CAMB and afterthat I obtained a message saying me to check the intervals of my parameter.
I don't understand why the program tell me and why the chain can't begin.
Can you help me?
Thank you a lot

COSMOMC : chain don''t start

The most likely explanation is that one of the new parameters can't be initialized to an allowed value because of a mistake in the .ini file. Possibly one of the new fixed params has a starting value outside the allowed range. Otherwise, there could be a mistake in the mapping of parameters to physical variables in params.f90 or the number of params in settings.f90.
