how to use MATLAB HMM toolbox for time series analysis?

Hi all,

    I am currently trying to use HMM toolbox for time series analysis. The major difficulty I am facing is that the toolbox is seems to handle discrete "symbols", rather continues variable. EX, 

    SEQ must consist of integers between 1 and 127. However, for time series analysis, it can be any.

    EMIT must also be symbols, but for time series analysis, it should be continues variable.

    Is there a way or toolbox to use toolbox to handle continue variables? 

    I am not sure if this question has been asked before, but I do appreciate if anyone can point me out. Thanks.
