in thread difficulty in matching 2 fields of a same line

example
14975:50417    1:N:0:CGATGT    -    chr11    108607098    GCTAGCTTACAGGTCACCTTGCTTGGTGTGGACAGT    JJIIJJJGGGIJHHHFJJJIJJJHHHHHFFFFFCCC    0    33:A>T,34:G>C    14975:50417    2:N:0:CGATGT    +    chr11    89267281    TCATGAAGTATAAAGTTACAGGGTGGTGATGTGATT    CCCFFFFFBHHHFIJIIIIIIIJAFH<FFHIGIIIJ    0
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];
    }
