Could you show us the exact system command you are using so that we can identify the mistake exactly.

    system($rnapath, "-p", "-noCloseGU", "-noLP", "$_") == 0 or die $?;
    $rnapath being the program called. Thank you for your patience.

      the bullet proof way: 
      my $pid = fork;
if (defined $pid and $pid == 0) {
  open STDOUT, ">", $fn or die;
  exec $script, @args;
  exit 1;
}
if ($pid) {
  waitpid($pid);
  $? and die "error on child: $?"
}
else {
  die "unable to fork: $!";
}
