Saving simulation data at the end of the process like this means you only save the data if every step of kmc_analyze goes off without a hitch.

For example, we had a hard time locating the actual mobility/mobility error for a simulation because kmc_analyze didn't complete, despite the fact that the preponderance of the workflow was completed, including the kmc itself. I think maybe one of the plots failed.
