Hi,
There are some faults when cosmomc evaluate the proposal matrix and then
the chains was cut off. I only added to a new parameter. I don't know why
Proposal matrix has negative or zero eigenvalues. what's matter in this condition?
and how to avoid. thanks
Chain 3 MPI communicating
Chain 1 MPI communicating
Current convergence R-1 = 0.2775182 chain steps = 2258

CosmoMC: some fault in proposal matrix
I ran into negative eigenvalues of the proposal matrix when using a primordial powerspectrum that is NaN for some values of k.
What is this parameter that you added? Some more information would be useful.
