Repository of Apollo examples and Data files

On this page, users can download example files provided with Apollo. The examples are organised by model type. The examples use four datasets that are provided with Apollo. These are included in the package, but on this site, we also provide the datasets in .csv format that can be opened in any text editor or spreadsheet software.
