uninitialized value with modelfit.pm

[Mutaz94]

Hi @rikardn:

This error is arising with PsN version 5.3.0 and NONMEM version 7.5.1 with a simple execute command.

Use of uninitialized value $result_array[14] in join or string at /usr/local/Cellar/perl/5.34.0_1/lib/perl5/site_perl/5.34/PsN_5_3_0/tool/[modelfit.pm](http://modelfit.pm/) line 1367.

The model executes successfully but without visualizing the run progress. Any suggestions? Thanks!

Device: MacOS M1 chip with perl 5.3

Thanks for reporting this. This is a warning coming from the subroutine that generates the results. Did you get the raw_results file? The run progress from NONMEM need the -display_iterations option

Hi Rikard: Thanks for your response. Yes, the raw_result file is generated, and the iterations are well displayed with -display_iterations. Any idea whats going on?

Usually warnings are a signal that something is wrong, but if you got all results as expected its hard to tell.
