Yes, it is. You can start with the Getting Started part of the help. After that you should know enough to start programming up your algorithm.

I want to know just the method, I have to calculate the mutual information of every two successives bloc , is this correct?

[Image Analyst]

I don't know that method. Do you have a web page with the formula?
