Re: Adding missing values into a hash

First, your output is not exactly a CSV (comma separated value) format.

Second You would probably better off storing your metadata keys in an array rather than a hash, because an array preserves the order of the data (and not a hash).

Third, a regex might be simpler than a split if you just want to remove the trailing comma:

while (my $line = <I1>) {
    chomp $line;
    if ($line =~ /##INFO=<ID=/) { 
        $line =~ s/,$//;
        # ...
}

Fourth, I do not see any \t in tour input.

Fifth, reading the file twice does not seem to be a very good idea. Can't you decide, based on the content, that you have finished reading the metadata and started to read the data?

Thank you very much for your answer :) You are right about the csv format, I was thinking in a excel. I thing that storing my metadata keys in an array rather than a hash it would be better, the problem is that I don't know how to asociate the metadata in the array with the values without doing it with a hash. Your third and fifth points look like very interesting, but I am "noob" and i don't know how to do it :(	[reply]
