Stock Synthesis executables for version 3.30.05.03 are available for 64-bit Windows, OS X, and Linux. The user manual has also been updated.
New features include
-
new column in both the length and age comp header tables for specifying the smallest sample size allowed; the default value is 1 to match SS 3.24; these values also affect the conditional age-at-length sample sizes
-
new option in the forecast file for specifying the selectivity to use for forecasts (not yet implemented)
Bug fixes include
-
issue with wtatage.ss_new
-
issue with settlement timing
-
issue with allocation groups and no allocation fractions defined
The SS 3.30 Change Log, which is available in the Document Library, has more information.
Note: if you are using a model that is already in SS 3.30 format, the following two changes need to be made before using the latest executables:
1. In the data file, add a new column to both the length and age comp header tables for the smallest sample size (set to 1 to match SS 3.24; the minimum value is 0.001)
Change this
#_mintailcomp_addtocomp_combM+F_CompressBins_CompError_ParmSelect
-1 1e-007 5 3 0 0 #_fleet:1_Fishery
-1 1e-007 5 3 0 0 #_fleet:2_Survey
to this
#_tailcomp addtocomp combM+F CompressBins CompError ParmSelect minsamplesize
-1 1e-007 5 3 0 0 1 #_fleet:1_Fishery
-1 1e-007 5 3 0 0 1 #_fleet:2_Survey
2. In the forecast file, add a new value after the forecast years for the not-yet-implemented option for specifying forecast selectivity
#_Fcast_years: beg_selex, end_selex, beg_relF, end_relF, beg_recruits, end_recruits
0 0 0 0 0 0
0 # Forecast selectivity (not yet implemented)
1 # Control rule method (1=catch=f(SSB) west coast; 2=F=f(SSB) )
