Excuse me if I might sound thick, but what exactly do you want to do with that script? I tried it and, some "uninitialized value" warnings aside, nothing happened. The output file wasn't much different than the input file and certainly didn't contain any random numbers.

might help to see some of what the input file looks like. I have a feeling this line is wrong:

if ($chrom[$i] =~ /chrd+/) {

unless you really are looking for "chr" followed by one or more "d". Probably should be:

if ($chrom[$i] =~ /chr\d+/) {

in which case its searching for "chr" followed by one or more digits.

Use the perl highlighter to post perl code. The php highlighter will mangle some perl code.

Besides that, I also don't understand what you are wanting to do.
