Yes, that's correct. It will say can't find data file.

I think the real issue, is something in the data file itself.

  I think that typically NMTRAN will generate an error for that (not
fortran), either can't find data file or INPUT FILE : I/O error at
record 1. It think this is coming from NONMEM reading FDATA, which is
surprising, usually NMTRAN is really really good at finding errors in
the data set, and will only write legal data sets. If it makes it past
NMTRAN, it has a legal (if not correct) data set.

time (like Excel)? also, open your data in something like notepad and take
a good look at it. look for odd characters or other unusual stuff.
