CosmoMC: Cannot stat file error

Post by Rahul Priyadarshan R » March 05 2022

Hi all,

I am new to CosmoMC and I'm trying to run CosmoMC using Planck likelihood data. When I run CosmoMC with test_planck.ini, I get the following error:

Code: Select all

 Number of MPI processes:           4

I have included the Planck likelihood files as well as the following likelihoods in the test.ini file: BK15, DES, Planck 2018 lensing, BAO and Pantheon18. When I try to run CosmoMC using test.ini for action = 0, the chains seem to run fine and I'm able to get the constraint plots in GetDist. However, when I run using test_planck.ini, I get the above mentioned error. Kindly help me fix this issue. Thanks in advance.

Looks like you don't have clik set up correctly, or clik files not linked as described in the Planck readme
