Greetings,

When i run the openmc-plot-mesh-tally command and select the statepoint file i get the following error message:

```
Traceback (most recent call last):
File "/home/ssartur/miniconda3/envs/montecarlo/bin/openmc-plot-mesh-tally", line 327, in <module>
  app = MeshPlotter(root, filename)

```

I just updated OpenMC to version 0.12 and i was not getting this error in the previous version. I am using Ubuntu 16.04, Conda 4.7.12, Python 3.7.9 and an environment with all the packages installed with Conda.  
Could somebody help me with this issue?

Thanks in advance,  
Artur Souza

Hi @Artur,

@RonRahamanANL fixed this issue [#1644](https://github.com/openmc-dev/openmc/pull/1644).

> [@Tally plotting error](https://openmc.discourse.group/t/tally-plotting-error/582/4):

> Just an update – @RonRahamanANL submitted a patch for this issue, so this should be fixed for the next version. I’d also encourage people to check out our [plotter application](https://github.com/openmc-dev/plotter) which has a lot more features than just mesh tally plotting.

Thanks very much @Pranto. I fixed the code and the plot-mesh-tally worked.

How did you do it? Just update OpenMC? I have update the code to v0.12.0, but the problem still exist.
