In this paper we explain the unzipping experiment as well as the basic theory of hidden Markov models (HMM). Using a specific type of HMMs, variable step-size HMM, in which the quantized distance variable is represented by a large number of states of the Markov model we try to determine the size distribution of the steps in the unzipping process.
