What do you mean "if two consecutive records have an equal readings". The code takes into consideration if two fields have same values the n sort it via score.
#!/tools/bin/perl
use strict;
use warnings;
use Data::Dumper;
open DATA, "file1" or die $!;
my %recordsArray;
my $header = <DATA>; #capture the header line
my @headers = split(/\t+/,$header);
while(my $line = <DATA>){
chomp($line);
my @records = split(/\t+/,$line);
# print "@records";
my $score = $records[2];
my $value = $records[3];
$recordsArray{$score}{$value} = $line;
}
print $header,"\n";
foreach my $score (reverse sort keys %recordsArray){
foreach my $value (reverse sort keys %{$recordsArray{$score}}){
print $recordsArray{$score}{$value},"\n";
}
}
