When you open a file the way he is, do you need to use a redirect?

    print "Can not open data file \n";
    exit;
}

open BLAST, "<result.fasta" or die "Can not open data file: $!\n";

You may try adding a print statement in the foreach loop to print $record to make sure it has the data you want in it.
