When attempting to use the MCMC fit with parameters other than those set by default, no samples are generated and this error occurs when the corner plot function is called:

For this particular run, I believe nwalkers = 1000, niter = 10000, and nburn = 5000. However, I have also used lower and higher values of the number of walkers, iterations, and burn-ins. The fits were attempted using star_ini files like the following:

Which work fine when using Multinest.
