in reply to difficulty in matching 2 fields of a same line

You can use array slice like so:

my @line; while(<DATA>){ chomp; push @line,split; } print @line[2,10]; #print 3,11 __DATA__ 4829:71370 1:N:0:CGATGT + chr6 126912761 GAAGGCATAGCCCGTTGGGCTGTGGTCAT +CAGCCTC CCCFFFFFHGHHHJHIJJJHIJIGHCGIIJJJJIJI 0 4829:71370 2:N:0:CGATGT + chr7 89349071 AGCCCTGCCCCCACCCCCCATTCTTCTTGACTGTCT C@@F +FFFFHHHGHJ JIJIJIIIIJJJJJJJJIIJIJ 0

However, it really depend on what you really want to print out.

    my code shud not be printing this line because here both fields are equal
    but it does because there are sm extra tabs.

    how do i tell it to compare only those fields starting with chr?

      Let a regex find what you need
      my @cmp = $line[$i] =~ /\tchr([0-9]+)\t/g; if (2 == @cmp and $cmp[0] != $cmp[1]) { print $line[$i]; }

        hey thanks for that u guys are really amazing!
