Version log GUTS package for BYOM
Version logging starts with 2.0 Beta 1 (earlier version have not been logged).
Version 2.0 Beta 1 (02/03/2017)
- The earlier GUTS1 and GUTS2 package have been merged in 2.0 beta 1. The files in the main folder are the ones to start with (reduced model, constant exposure, analytical solution, only pure SD and IT). The other folders contain the more fully featured 'reduced' and 'full' models.
- This version is made fully compatible with GUTS version 4.0 Beta 2, and the examples make use of several of the new features.
- The naming of the symbols and the model structure now closely follows the new definition as will be used in the GUTS e-book (to be released end of 2017). The model is still the same, and all analyses types that could be performed with the old version are still possible. The examples provided will cover the most common types.
- In the full model, there is an option to set damage repair to fast. This effectively implies that the actual internal concentration is used as dose metric.
- The derivatives.m for the full and reduced model contain the code to include time-varying concentrations. This is demonstrated in the diazinon case studies.
- For the GUTS e-book, we decided that the log-logistic distribution should be the standard for GUTS. This is therefore also the case in this package. In call_deri, you can still find the option for the log-normal.
- The options for the ODE solver have been moved to globals so they can be set in the script.
- For IT and the mixed model (IT and SD combined), a long time vector is needed for the calculations. This was earlier captured in prelim_checks, but is now placed in call_deri for the GUTS package.
- The starting values estimator has been updated and should work well for the simples cases (reduced model, no dynamic damage stage) and constant exposure.
Version 2.0 Beta 2 (2017)
- Several errors in startvals.m that led to errors for some data sets. Also added a short range for hb. Also corrected the call to startvals in all scripts apart from byom_guts_start.
- Corrected the legends for the dieldrin cases: should be ug/L and not uM.
- Forgot to change "clear all" to "clear, clear global" in several of the example scripts.
- Removed the use of the log-normal distribution in call_deri, as we will use the log-logistic as the GUTS default.
Version 2.0 (27 April 2017)
- No additional changes to the beta 2 version.
