Hi Sandy_Bio_Perl,

Apologies for not explaining my question properly in the first place

I recommend you read How do I post a question effectively? and Short, Self Contained, Correct Example. Showing your own coding efforts not only gives people trying to help a basis to start from, it also shows that you're not just trying to abuse PerlMonks as a code writing service. Not only that, boiling down your code into a SSCCE and trying to explain the problem will often help you yourself to figure out the issue at hand.

Anyway, BrowserUk and Marshall already answered your question and provided code; the only difference is that instead of their %freq resp. %histo hashes being populated from the data, you simply need to pre-populate it.

Hope this helps,
-- Hauke D
