hello Monks
#!/usr/bin/perl 
use LWP::Simple;
my $url  = "http://www.hprd.org/edownload/HPRD_FLAT_FILES_090107";
my $file1 = "HPRD_FLAT_FILES_090107.tar";
# get the data
is_success(getstore($url, $file1))
    or die "Mark probably broke the server again!\n";
 use Archive::Tar;
    my $tar = Archive::Tar->new;
$tar->read('HPRD_FLAT_FILES_090107.tar',1);
    $tar->extract(); 
$output = "arch.txt";
# open file
open(FILE, "<\HPRD_FLAT_FILES_090107\PROTEIN_Architecture.txt") or die("Unable to open file");
open(OUTPUT1, ">$output") or die("Unable to open file");
# read file into an array
@hprdArchi = <FILE>;
foreach $line (@hprdArchi){
if ($line =~ s/^/'/ and $line =~ s/\t/','/g and $line =~ s/$/'/){
print OUTPUT1 " $line ";
}
}
the error i am getting is
