Dear Ethan, the simplest solution to solve your problem would be to use the bootstrap command of PSN (http://psn.sourceforge.net/). With PSN installed you would simply do: bootstrap final_model.mod -samples=200 PSN would take care of unsuccessful runs and provide a nice summary of the individual

Hi, I dont understand why this wasn't fixed in NONMEM VI. It was a well known bug in NONMEM V and has caused lots of grief for users. I hope the NONMEM VII developers have got this high on their list of NONMEM bugs that need to be fixed. Nick Dear users, I am trying to compare several

Dear users,    I am trying to compare several specific PK/PD study designs by:  -- run 200 simulations with the final model (develope from original dataset)  -- fit the final model to the 200 simulated dataset To achieve above, I used $SIM SUBPROB=200 option  however, nonmem would  completely

You can use S+ (or R that has an advantage of being free) to control nonmem, but you may need a bit of programming. One possible scheme is to prepare template control stream (with $SIM SUBPROB=1 option) and then run the loop for(i in 1:NumerOfIterations) { # prepare control file from a
