Thanks for helping out with this I really appreciate the input from you guys.

I tried the above code but I get an error:

Use of uninitialized value in printf at parse_result.txt.pl line 23, <$fh> line 45.

The code I used was practically the same as yours except for changing the name of the input file to results.txt and changing the " " to "\t" 

#!/usr/bin/perl
use strict;
use warnings;
use Text::CSV;


my @result;
my $csv = Text::CSV->new ( { sep_char => '\t ' } )  # should set binar
+y +attribute.
                or die "Cannot use CSV: ".Text::CSV->error_diag ();

open my $fh, "<", "result.txt" or die "result.txt: $!";

while ( my $row = $csv->getline( $fh ) ) {
    if ($row->[0] =~ m{\QHWUSI-EAS95L_0025_FC:3:1:5232:1082#0//E}) {
        if (@result) {
            $result[1] = $row->[3];
        } else {
            $result[0] = $row->[2];
        }
    }
}
#printf "%s\t%s\n", @result;
printf  @result;
$csv->eof or $csv->error_diag();
close $fh;
