Dear Ranita, Since this question does not directly concern NONMEM it would be better suited for the PsN mailing list.
That being said I see that you are using a very old version of PsN (as in at least 6-7 years old). I suggest that you install the latest version and try again. If you still have problems I might be able to help so please let me know via the PsN mailing list!

I tried to run a VPC for a model with has $SIZES LVR=46 $SIZES PL=15 Unfortunately, this failed and the error message I got was: Problem number 1 does not exist! At lib/model_subs.pm line 4638. However, when I commented out $SIZES PL=15, it worked perfectly. Unfortunately, for another model which has the following $SIZES, I am still unable to get the VPC running despite commenting out some/all of the $SIZES $SIZES LTH = 46 $SIZES LVR = 99 $SIZES LNP4 = 6000 The error message I got was the same and the vpc command I used was: vpc run_ S_BJCP_AZOLE_VPC.mod -samples=200 -bin_by_count=0 -bin_array=0.25,0.5,1,2.5,8,10,11,12,13,14,16,24 -dir=VPC_ S_BJCP -idv=TAD -lnDV=3 -predcorr -stratify_on=STRT Could anyone advice on how to resolve this problem?
