I have a data set for which I have experienced the following:
1. A Nonmem data set was prepared from SAS/R from an *.xpt file; however, when I tried to run under PSN it returned that it couldn't find the data set. 2. Using a data set that I had previously prepared with SAS and run under PSN (i.e., not from an *.xpt file), I manually added additional subjects with the same sampling scheme and the data set ran under PSN. However when I looked at the outputted fit file only the original subjects had been read in and parameters estimated for them by PSN; 3. When I run estimation with the same data set under Wings it runs okay. Has anyone had a similar experience with data from an *.xpt file and if so how can it be addressed?
