Website and discussion board


  • 17 May 2019: the openGUTS.info website is now on-line. This site will host the openGUTS standalone software, but already offers the Matlab prototype for download.
  • 8 Oct. 2015: I have moved debtox.info to another web hoster due to problems with the services from KPN. There might still be some glitches; if you run into unexpected behaviour, please let me know.
  • 13 August 2015: the site has a new look and feel! I moved everything from a php-based web-builder application to plain html. This makes it easier for me to maintain, and to move to another webhoster, if needed. The important old php links should redirect automatically to the new html pages. Some glitches may occur .... so please contact me if you hit an unexpected result.
  • 7 August 2015: moved my DEBtox Research activities to a dedicated website: www.debtox.nl. This info site will remain the place with information on models, sorftware, e-books, publications and courses.
  • March 2015: the hits counter at the bottom of the page has now exceeded 100,000 hits!
  • 21 June 2012. Check out Roman Ashauer advertising TKTD modelling in SETACs newsletter over here.
  • 5 May 2012. On the discussion board, I started a forum on "Ecotox Essays".This forum will present short opinions and critical comments on an ecotoxicological topic. I will try to regulary write a contribution, but I also highly welcome contributions from others! See the board for further details.

  • 26-27 September 2020: update of the BYOM tox-related packages. GUTS package: this update is especially a good idea when using the ODE-solver versions in the "experimental" folder. DEBtox2019 and DEBtox_classic packages: more efficient/accurate ODE solving for time-varying exposure. For all these packages: now allowing double time points in the exposure definition (as in openGUTS). See the BYOM page.
  • 26 September 2020: update of the BYOM package. This update is especially a good idea when using the ODE-solver versions in the "experimental" folder. Also: now allowing double time points (as in openGUTS). See the BYOM page.
  • 24 September 2020: update for BYOM to version 5.2. Modified the parameter-space explorer to work reasonable well for 6/7 free parameters (best left to experts). Further modifications for time-varying exposure, now allowing double time entries like in openGUTS and efficiency improved for hard-pulsed exposure (these changes also require updates for the packages that use glo.break_time ... working on that!). See the BYOM page.

  • 13 August 2018: a quick update of BYOM to v. 4.2b. This was needed as I found some errors in conjunction with GUTS package. See BYOM page for details.
  • 9 August 2018: updates of packages 'dose-response', 'acute Calanus', and 'support marecotox'. The dose-response package also has a nicer walkthrough. See BYOM page.
  • 7 August 2018: new version of BYOM and the GUTS package, fixing the issue with the likelihood-region method. More details on the BYOM page.
  • 28 June 2018: running simulations for GUTS, I am getting confirmation that the likelihood-region method (as implemented in BYOM) is yielding exaggerated confidence intervals on  model predictions. More details on the BYOM page.
  • In 2018/2019 we will be producing a user-friendly software for GUTS. More information.
  • 1 February 2018: New versions of BYOM and the GUTS package. See the BYOM page.
  • 12 May 2017: Spotted a small error in BYOM when calculatin the intervals on LC50s with the likelihood-region method. This corrected in a small update to version 4.01.
  • 27-28 April 2017: Release of BYOM 4.0 on the BYOM page. This is a major update, with many new features, but old scripts and packages will not work anymore! All packages have been updated; the two GUTS packages have been combined, and some have been renamed for clarity.

  • 3 April 2015: major update of BYOM. Some alternative optimisation methods are included, plus the possibility to fit parameters on log-scale. And ... the possibility to publish the code in Matlab (see the walkthrough of the BYOM code). Also a new version of the manual is provided.
  • 18 February 2015: update of BYOM and the GUTS2 package. Main change is to avoid warnings with newer versions on Matlab (due to different way of dealing with interpolations), and the option to plot in black-and-white with different symbols (as in the DEBtoxM flavours).
  • 2 January 2015: tiny 2.02 update for BYOM, and extended the BYOM manual, and gave a seperate entry on the BYOM download page.
  • 17 December 2014: New version of the BYOM files to version 2.0. Major change is the possibility to have more than one data set per stage, and a brand new simulation engine.
