NONMEM 7.2 and Pirana/Xpose4

I am new to NONMEM 7.2 and am having some issues generating the goodness of fit plots within Pirana or Xpose through the R console. I believe the problem is that the sdtab101 table is not created. When I try to open this file it is completely blank. I am having this problem both with a practice dataset as well as my own dataset. Below you will find the code that I am using to create the sdtab file. I appreciate any help so that I can continue analyzing my data. $TABLE ID TIME DV IPRED PRED IWRES CWRES WRES NOPRINT ONEHEADER FILE=sdtab104 Margaret Thomson, PharmD PhD Candidate University of Tennessee Health Science Center
