Hi Antony,
I'm using GetDist.py to process the sampled MCMC chains, I found that the label 'parameter_names' in *.ini file is not used at all, so that if I want to use the parameter names that I want, I will have to place the file_root.paramnames file together with the chains.
So I checked the contents inside GetDist.py, and made the following modifications, then everything is OK.
paramnames = ini.string('parameter_names', '')
# Create instance of MCSamples
if paramnames is not None:
print ('paramnames is not empty: %s'%(paramnames))
mc = MCSamples(in_root, files_are_chains=samples_are_chains, paramNamesFile=paramnames)
else:
mc = MCSamples(in_root, files_are_chains=samples_are_chains)
paramnames is missed inside GetDist.py
