measure.rb#L736:"#{radPath}/options/treg.opt", 'r') do |file| is the line that's throwing, because the file does not exist. I'm not sure what went wrong though during the Radiance run. Are you sure your Radiance Daylighting Measure is fully up to date?

I have a test model locally that I just used on OpenStudioApplication 1.2.0 on Ubuntu 18.04, with the latest version of the Radiance BCL measure, and it worked fine.

Hi thanks for your help.

It is updated, the problem was that the mesh and the sensors were not assigned to the thermal zone.
