Hello all i would like to blast multiple sequence individually one after another and output i need in excel sheet, i tried like this:

use Bio::Tools::Run::StandAloneBlastPlus;
Bio.SearchIO.BlastIO.blast_xml
use Excel::Writer::XLSX;
use strict;
use Bio::SearchIO;
for file in *.fasta
do
    echo $file
      out=`echo $file | sed 's/_.fasta_/_.excel_/'`
my $factory = Bio::Tools::Run::StandAloneBlastPlus->new(
    -db_data => 'Autotransporters.fasta',  # Specifies the file to use for database
    -create => 1               # Creates a new temporary database
);
my $result = $factory->blastn(
    -query => '$file',                # Specifies the query file
    -outfile => '$out' );  # Specifies the output location
$factory->cleanup;                        # Deletes the temporary database files

Error :
