Fit current region

Starts the process which fits the model curve to the measurements of the selected regional TAC. For compartment models the fit is an iterative optimization, while for some other models only a single calculation may be sufficient.

Reference model: Fitting the reference region itself is not possible, an information message will be shown.

Fit all regions

Performs fitting for all TACs of the study using their current regional model definitions.

Reference model: The reference region itself is skipped without fitting, and the information is stored in the console log.
