Subject: [NMusers] NP4F error 
Date: Thu, May 19, 2005 2:57 am 

Dear colleagues, I have encountered a NONMEM error message which I had not 
seen before.

0MINIMIZATION SUCCESSFUL
  NO. OF FUNCTION EVALUATIONS USED:  640
  NO. OF SIG. DIGITS IN FINAL EST.:  5.5
0PRED RETURNS DIFFERENT OUTPUTS WITH THE SAME INPUTS
0PROGRAM TERMINATED BY NP4F

The message is apparently issued at the very end of the run and 
unfortunately prevents NONMEM from reporting the parameter estimates. The 
table step is also omitted. Has anyone seen this particular message before 
and can perhaps give an explanation or recommend a remedie? Any input will 
be appreciated.
Thanks in advance.
I.Meineke
