As Stock Synthesis usage has grown, so has the number of tools to work with it. These include repositories on github with the stock-synthesis topic as well as:
- r4ss: Create plots of Stock Synthesis output and functions to work with Stock Synthesis in R.
- ss3diags: Run advanced diagnostics for Stock Synthesis models.
- ss3sim: Conduct simulation studies using Stock Synthesis.
- SSI: Stock Synthesis Interface, a GUI for developing models and running Stock Synthesis. Links to r4ss.
- SS3 Shiny helper app: Visualize common selectivity pattern options available within Stock Synthesis.
- SSMSE: Use Stock Synthesis operating models in Management Strategy Evaluation.
- sa4ss: Create accessible R markdown stock assessment documents with results from Stock Synthesis models. Note this tool is intended for use by analysts within the Northwest and Southwest Fisheries Science Centers currently.
- Data limited tools - Options included Simple Stock Synthesis (SSS) and Extended Simple Stock Synthesis (XSSS), as well as SS-DL-tool, a shiny app that includes XSSS and SSS in its functionality.
