Hi Doug and many thanks for your reply and help. If blue means neg, red/yellow is positive does this means that where is blue we have a decrease in FA for while positive means an increase?
How I know if there is a decrease in controls versus patients and not opposite (FA decreases in patients versus controls)? Is my C = +1.00000 -1.00000 correct if I am interested only in group differences and I want to eliminate the age. Also can you please take a look on my y (please see the attached file) to confirm if is correct? Thank you very much and have a great weekend!
