Dick,
I notice one small typo in what you sent:
s4=V4/1000
The "s" is lower case. NM-TRAN does not recognize s4 as "scale for compartment 4". It only recognizes upper case S4. Hence S4 defaults to 1. It may be well be that theta(8) is not estimated (i.e., inital est = final est ; gradient always 0). This will happen if there are no observations from CMT 4. Or, if there are such observations, it will happen because V4 does not enter into the model.
