Thank you very much for such a quick response!

I am going to classify two group of patients: responders versus non-responders... As the matter of fact, I also have fMRI and DTI data of these subjects - but I would prefer to start from structural images... Therefore I'd like to clarify structural (and possibly functional) patterns of non-responders and try to make predictions...

Thank you for your time!

... and for the advertisement=) I'm reading that right now...
