Hi @lz152,

This error message means that your statepoint file was generated by a previous version of OpenMC (< 0.13.1) and is incompatible with the statepoint files produced with the newest version. To use the openmc-plot-mesh-tally script you’ll need to either use an older version of OpenMC or re-run your simulation with OpenMC v0.13.1 to generate a new statepoint file.

I’m sorry there isn’t a better alternative at this time. We could think about a tool for updating statepoint files from older versions of OpenMC if possible with enough interest, but those are my recommendations at this time.

All the best,

Patrick
