Thank you very much Chris--I will read the numerical recipes.
I should have explained more about the data.
I extracted unique 5 mer patterns of amino acids from a database and look
at their secondary structures.
I want to know is there a relationship between the amino acid sequence and
the secondary structure.
This is the reason I thought Markov modelling might give me some ideas.
