Hi everyone, i am using bioperl to do blast 2 sequence. I need to output as a tabular format. I saw some post where they mention we need to use -m8 to get tabular output. But in my code its not working. Can anyone help me out what i am missing in this code.

use Bio::Tools::Run::StandAloneBlastPlus;
#use Excel::Writer::XLSX;
use strict;
use Bio::SearchIO;

my $factory = Bio::Tools::Run::StandAloneBlastPlus->new(
    -db_data =>'test.fasta', # Specifies the file to use for database
    -create =>1 # Creates a new temporary database
    );
my $result = $factory->blastn(
    -query =>'H1.fasta', # Specifies the query file
    -outfmt => -m8,
    -outfile =>'out_H1' # Specifies the output location
    ); 
$factory->cleanup; # Deletes the temporary database files
