Stock Synthesis executables for version 3.30.08.04 dated 2017-11-10 are now available for 64-bit windows, 32-bit windows, linux, and OSx. The GUI has also been updated, please give it a try and give us feedback.
There is one small fix and a few small changes in this release:
- fix forecast recruitment error when spawn_month>1
- after bias adjustment ramp is calculated, set bias adjustment to 0.0 for years after recdev_end. This is added because r4ss can calculate a bias-adjustment ramp that extends into the future. Bias-adjustment is illogical in the forecast, so SS now hardwires ramp to go to 0.0 after the last year of the main recruitment deviations.
- Adjust an array dimensions to allow very long forecasts. But note that a forecast longer than the expected interval between assessments should only be done at forecast loop 2. Forecast loop 3, that forecasts quotas for future years then calculates F to match those quotas, should only be done for a forecast of a few years, such as the expected interval between assessment updates.
- In addition, I continue to use your feedback to improve some warnings.
Here is another reminder about the new output file, ss_summary.sso. ss_summary.sso is designed to put key model outputs all in one concise place. It is organized as a list. At the top are some descriptors. Then the likelihoods for each component, then the parameters and their standard errors, then the derived quantities and their standard errors. We created this output to make it easy to compare the results as we update the code, but we think it will find plenty of other uses also.
The SS 3.30 Change Log, which is available in the Document Library, has more information. We updated the user manual to reflect these changes.
(Still) at the top of the current to-do list are:
- change tagging parameters to use a much more concise design matrix approach
- add F0.1 to the Benchmark and Forecast code
- add a constant recruitment option to forecast
- add a 3-parameter Ricker Power spawner-recruitment relationship
- develop controls for bycatch fleets so they can be managed better in Benchmark and Forecast
