Hi,
I am using CosmoMC-June2016. Now I am trying to constrain a new model with some extra paramters, which runs very slowly. I use estimate_propose_matrix and action=2, but there was not any *.covmat produced. How can I get the propose matrix?
Thanks

Re: CosmoMC: estimate the propose matrix
Just run a new chain without one (or, better, one containing a subset of the parameters that you do have): as long as you are using MPI and the proposal learning options set, it should still work. Just make sure all your propose widths of the new parameters are fairly small.
