  • 26 May 2020: update of the Matlab version of openGUTS. This version 1.1 repairs the error that was discovered (the standalone still has this error, so do take a look at the dedicated document for this error). See download page.
  • 20 May 2020: document explaining the error linked to the error warning (on this page above, and on the downloads page). Also updated the 'list of known issues' with this error, and a few more small GUI bugs.
  • 20 May 2020: openGUTS on-line, completely-DIY, short course is now available. See course page.
  • 19 May 2020: error found in the IT calculations. More information and workarounds/repairs coming soon.
  • 10 May 2020: small update to the interpretation document, adding a section with a brief description of the model and its parameters (and what they do). Furthermore some small textual changes and error repair.
  • 21 April 2020: updated the "list with known issues" with a few small bugs and additional items for the wishlist. See download page.
  • We will provide a half-day short course on the openGUTS software at the virtual SETAC Europe in May 2020. See the SETAC web page, and scroll down to "TC11 - Introduction to Effect Modelling with the User-Friendly Software OpenGUTS." We need to see how SETAC will support the short courses on-line, so more information will follow. There will also be a poster on openGUTS at this conference (ID 4.07P.4).
  • 12 December 2019: added the source code and an updated version of the design document. See download page.
  • 10 December 2019: version 1.0 of the standalone is available for download (with manual, but not yet with the source code). Furthermore, a new version of the Matlab version (previously known as the prototype). Also updates of the manuals and for several of the background documents. See download page.

  • 18 Sept. 2019: the planned course on openGUTS in October 2019 has been cancelled. Unfortunately, we had insufficient registrations.
  • 30 Aug. 2019: small update to the design and interpretation documents on the download page.
  • 22 July 2019: update of the test document (includes ring test but also additional data sets with difficult properties). See download page.
  • 12 July 2019: another update of the prototype, solving a few minor bugs and adding some nice features (wait bars and error boxes). See download page.
  • 23 May 2019: tiny update of the prototype. It now includes the same set of exposure profiles as used in the EFSA scientific opinion. See download page.
  • 22 May 2019: added a walkthrough through the code of the prototype (made with Matlab's publish option).
  • 21 May 2019: a number of background documents are already downloadable.
