The Options tab allow selection of the computation method and the Ke0 value.
In the Computation Method menu, select the method Phoenix uses to perform the semicompartmental analysis.
Linear uses a linear piecewise PK model.
Log uses a log-linear piecewise PK model.
Linear/Log start with linear to Tmax and then log-linear after Tmax; this is also the default option.
In the Ke0 field, type the value for the equilibrium rate constant.
