Reply To: Group comparison in Lead Group

Hi Rubens,

maybe your regressor is set up incorrectly. It should be all ones for group 1 and all zeros for group 2.
So assume you have e.g. 5 top responders and 5 poor responders and want to run a paired t-test on their VTA intersections with the STN, then you would add a vector like
[1
1
1
1
1
0
0
0
0
0];
as the regressor. Then click on the group comparison button.

And then it should work.

Best, Andy
