We have invested a lot of time and effort in creating SimThyr, please cite it when using it for scientific projects and publications.

In order to cite SimThyr in publications use:

  • J. W. Dietrich (1994-2019). SimThyr, a simulator of thyrotropic feedback control. RRID:SCR_014351. doi: 10.5281/zenodo.1303822. URL http://simthyr.sf.net.

Additionally you might want to cite one of the following papers:
