Dear all I am using NCBI BLast for sequence alignment .The URL of NCBI blast is http://blast.ncbi.nlm.nih.gov/Blast.cgi?PROGRAM=blastp&PAGE_TYPE=BlastSearch&LINK_LOC=blasthome I am using mechanize perl module to input my enteries and hoping to get the output result.My program is

use strict;
use Data::Dumper;
use Carp;
use WWW::Mechanize;

use WWW::Mechanize::Firefox;
use WWW::Mechanize::Sleepy;
my $address = 'http://blast.ncbi.nlm.nih.gov/Blast.cgi?PROGRAM=blastn&
+BLAST_PROGRAMS=megaBlast&PAGE_TYPE=BlastSearch&SHOW_DEFAULTS=on&LINK_
+LOC=blasthome';
my $outfile = "outnewww.htm";
my $file    = "n.txt";


my $organism = "Aspergillus";
my $mech = WWW::Mechanize->new();
#my $mech = WWW::Mechanize::Sleepy->new(sleep=>1);
$mech->get($address);
sleep (10);
$mech->field( 'QUERYFILE', $file);

$mech->field( 'qorganism', $organism);





$mech->set_fields(
        
        
        # But the rest of these fields are recognized
        'QUERYFILE'    => $file,
        'qorganism' => $organism
        
);

$mech->submit;
#my $result = $mech->content();
#print "$result\n";
my $output_page = $mech->content();

open(OUTFILE, ">$outfile");

print OUTFILE "$output_page";
close(OUTFILE);

The program is running alright but the problem is that ncbi blast auomatically updated for some second and then final output come.So what this program store is the intermediate page where it is coming"This page will be automatically updated in 1 sec until serach is done."Not able to get final alignment result.Plz help me in this regard.
