Dear all:
I wonder if anyone has experience with LSODA error code -5. I recently
slightly modified a dataset by applying a conversion factor (~0.9) to the DV
and rerun the same Poppk model which used to be ok with the dataset before
conversion. However, I encountered the following messages during running. I
appreciate the tips if you have. Thanks a lot.
Best wishes,
Yun

LSODA error code -5
Hi Yun,
LSODA messages are not very informative or specific. They just tell that the model has numerical problems. You may try to start with the new initial conditions (e.g., divide all CL and V initial parameter values by 0.9) and/or change TOL value to the lower value (8 or 9?).
Thank you,
Leonid
