    Hi Dave,

    So i have created a hash with the first to columns as an identifier. What i need to is compare the hash values which are in an array.

    The code is given below

    Best and Thanks

    open($f,$ARGV[0]); while(<$f>) { chomp; @l = split "_",$_; $h{$l[0]."\t".$l[1]} .= $l[2]."\t"; } foreach (sort keys %h) { @n = split "\t",$h{$_}; if(scalar @n == 1) { print "$_\t$h{$_}\n"; } else { @s = sort {$a <=> $b} @n; for($i=0; $i <= $#s; $i++) { if($i == 0) { push(@na,$s[$i]); } else { $len = $#na; if($s[$i]-$na[$length] <= 45) { next; } else { push(@na,$s[$i]); } } } foreach $k(@na) { $hn{$k} = $_; } } }
