### [CosmoMC] Errors with setting omegach2=0

Posted:

**July 13 2017**I'm trying to set omegach2 = 0 for a mini-investigation but I'm getting errors. The output file shows:

In the params.ini file, I made the following changes

CosmoMC seems to be running for omegach2=0.04 at the moment, though I'm hoping to get it to run with omegach2=0. This might be because I should be assigning a prior to more parameters? Please advise, thanks.
