A number of things.

One: $data has not been defined. I think you want to look at $chunks[$index]

Two: The indices for @chunks goes from 1 to @chunks-1. So be careful!

Three: In your regular expression, you have captures within captures. Note that (abc(def)(ghi))(xyz) will match the following:

$1 = abcdefghi
$2 = def
$3 = ghi
$4 = xyz

Four: I am uncertain if you know what it is that you are matching. See the following code and results. It will show what you are matching, and what you could be matching if you used a simpler regex. I don't know if this is what you want, but it should get you started in the right direction.

Code

#!/usr/bin/perl
use strict;
use warnings;

my @chunks = <DATA>;

foreach my $i ( 0 .. @chunks-1 ) {
    my $data = $chunks[$i];
    no warnings;
    if ( $data =~m/(\d+)\s{2,}(\d+) \s{2,}((\d|-)?(\d|,)*\.?\d*)\s{2,}
+((\d|-)?(\d|,)*\.?\d*)\s{2,}/) { #/ ) { 
        print "<$1> <$2> <$3> <$4> <$5> <$6> <$7> <$8>\n"; 
    }
}
print "\n\n";
foreach my $i ( 0 .. @chunks-1 ) {
    my $data = $chunks[$i];
    no warnings;
    if ( $data =~m/(\d+)\s+(\d+)\s+(-?\d*,?\d*\.?\d*)\s+(-?\d*,?\d*\.?
+\d*)\s+/) { #/ ) { 
        print "<$1> <$2> <$3> <$4>\n"; 
    }
}
