program terminated by NP4F

Dear uses, I am getting this error from the nonmem, pop parameters was estimated but no table output "0PROGRAM TERMINATED BY NP4F PRED RETURNS DIFFERENT OUTPUTS WITH THE SAME INPUTS MESSAGE ISSUED FROM TABLE STEP" What does this NP4F, and Pred returns different outputs with the same inputs mean? thanks

Dear Ethan, can you double check your data and see if you have any missing entries or blanks in some rows ? I recently submitted a similar issue to nmconsult to further investigate this error that happened with a dataset having an individual with some missing covariate values. Apparently the NMTRAN data-preprocessor fails, in some circumstances,to detect that some rows has less entries than the number of columns specified in $input. The run proceeds normally and the error is not detected until the Table step. Bests, Samer
