Thanks everyone for such a quick response. Changing CMT from 3 to 2 in my dataset was enough. Thank you so much! Regards, Sumeet Singla

ADVAN3 is for a fixed 2 compartment PK model with no heart rate compartment. There is no 3rd compartment in this model, hence your error message. You need to use an ADVAN with no fixed model, eg. 6 or 13, and define your compartments in the $MODEL and $DES blocks.

Can anyone please help me with that? Looks like CMT=3 which is associated with heart rate is turned off. How to turn it back on? I have attached error, sample of my dataset and control stream.
