Guys,

firstly, thanks for the help.

Now that I’ve done the changes I wanted. What is the pathway I should walk now to plug in the, let’s say, _ **itkMachadoMutualInformationImageToImageMetricMetric.h** _ and _ **itkMachadoMutualInformationImageToImageMetricMetric.hxx** _ , files resulted from the changes I did, and by changing _ **itkMattes…** _ everywhere in the original files by _ **itkMachado…** _ , in order to use it inside ITK environment?

I mean, Can I call those new files just by putting them inside the project folder and including them in the beginning of the main file? is that all? Or should I copy and paste those files somewhere else?

Thanks!
