Hi Emongold. Those .json files are created by the backend when you run an analysis. In other words, they are specific to the analysis you are trying to run and are not provided as part of the download. The reason that they are missing is that there was probably an error somewhere early on in the analysis. Can you try to load example 3 and click run without changing anything? It should run out of the box. If it fails, send me the output so I can review in detail what the issue may be. Thanks, Steve.
