Do I have to specify the covmat and the bestfit when restarting chains? #153

Open mtagliazucchi opened 1 year ago

I have some chains produced using the bestfit and the covmat of a previous run. I need longer chains and so I should use the -r option. Is necessary to specify the same covmat and bestfit files when restarting the chains?

Dear user, Your are raising issues on the old MontePython v1 and v2 repository (active in 2013-2018). As clearly stated on this wiki, issue https://github.com/baudren/montepython_public/issues/55: since April 2018 and v3, the MontePython repository has moved to https://github.com/brinckmann/montepython_public Please go there to clone a recent, working and maintained version of the code. Then, if necessary, please raise your issues in that repository. (In this particular case, in MontePython v3 the chains start from the last step in the chains so the bestfit is not necessary and the covmat is automatically loaded if present in the folder with the name your_chains/your_chains.covmat otherwise it should indeed be provided as input. I can't guarantee the functionality of all of this is exactly the same in v2 of the code as that is no longer maintained, but I think it is) Best, Thejs
