I have a set of data for three kinds of patients who :
1- have the disease
2- might be at risk to have the disease
3- healthy people who dont
I need to compare x,y, and z coordinates of their MRIs.
What kind of T test should I be using as I'm very confused about it?

Hi,
Please refer to the documentation and examples related to multcompare for multiple comparison tests.

Hi,
If the x-coordinates are in the vector x and the category of the disease categories are in the vector d, you can perform the test as follows.
[p,t,stats] = anova1(d,x);
c = multcompare(stats);
