[Bioperl-l] problem setting mismatch penalty in StandAloneBlast.pm without setting quiet()

[Scott Markel]

I'm using BioPerl 1.4 on a Windows XP box.  When I set the
mismatch penalty for blastn, I get both the "-q" command line
option, which I want, and errors getting redirected to /dev/null,
which I don't want.  The problem seems to be the following
line in Bio::Tools::Run::StandAloneBlast's _setparams():

   if ($self->quiet()) { $param_string .= '  2>/dev/null';}

A constructor call

   $factory = Bio::Tools::Run::StandAloneBlast->new(@params);

followed by either $factory->q(-3) or $factory->quiet(-3)
both result in "-q -3" being added to the command line *and*
"  2>/dev/null" being appended to the command line.

I've tried calling $factory->verbose() with verbosity values
of -1, 0, 1, and 2, but this didn't get rid of the /dev/null
redirection.

How do I set the mismatch value without tripping $self->quiet()
in StandAloneBlast.pm?
