Every software will contain errors. Even though
openGUTS is extensively tested, we are sure that it contains
errors. Some of these will be small glitches that are more
of a nuisance than a problem. However, there may be more
serious errors that affect the accuracy of the output, in
places were we did not test the software. We like to notify
the users as soon as possible when such an error is
identified (and offer possible workarounds). To this end, we
ask you to register for an email list by sending an email to
Tjalling Jager (see email at bottom of this page). This list
will only be used for information on important errors and
openGUTS is free and open source software: you can

Standalone openGUTS software
Download will follow ... we are currently in the Beta test
phase. We expect to officially release the software by
This is a standalone executable that runs on Windows
prototype (v.0.7 of 12 July 2019, ZIP file, 705
KB). Check the version log.
A short manual can be downloaded below (under the
section 'Manuals and documentation'). Take a walkthrough
through the code (made with the 'publish' option of
Matlab) to see what it does.
The prototype requires that you have Matlab installed. It is
designed in R2018a, but should work error-free with version
R2014b and later. The prototype has the same functionality
as the standalone version, but lacks the user interface and
the output report. Both version are able to use the same
input files for the data sets and the exposure profiles. The
prototype will be handy for trying out modified GUTS models
(e.g., more complex TK/damage modules) or modified analyses
(e.g., custom graphs). Since the prototype and the C++
source code follow the same structure, the prototype can be
used for future development of the software.
Warning. This is a
'beta' release of the prototype. It is fully functional, and
thoroughly tested (see also ring-test results below), but
may still contain some bugs and/or errors. As far as we can
tell, it provides exactly the same output as the current
test version of the standalone software. So when the
standalone is subjected to more extensive testing (second
half of 2019), this may throw up errors that also affect the
prototype. If you worry about this, make sure to register to
be warned in case of errors (see top of this page).

- Guide for interpretation of openGUTS model output.
This document runs through a well-behaved example, but
also presents and explains several typical nasty cases.

- Technical design/background document for openGUTS. Download
(version 20 May 2019). This document is likely to
change a bit before the end of the project.
- Test results for openGUTS, comparing the output of the
Matlab prototype (v0.7) with the standalone (beta 1).
These tests include the GUTS ring test exercises, and
also results with BYOM, Morse and Mathematica are shown.
