cosmomc initial parameter values

Post by Brian Powell » December 10 2007


Is there a way to fix the initial parameter values even when using a covariance matrix? Setting the initial widths in params.ini does not appear to do the trick.

Any help would be much appreciated!

You can set the central values in params.ini and zero widths.
