Dear SPMers,
I am ananlyzing a 2 x 2 factorial analysis:
Pretreatment with Drug 1 =================> Posttreatment with Drug 1
Pretreatmetn with Drug 2 =================> Posttreatment with Drug 2
I selected full factorial and entered the following Levels under factors
and then under cells (then selected SPECT images for each cell):
Pretreament with Drug 1 has level [1 1]
Posttreatment with Drug 1 has level [1 2]
Pretreatmetn with Drug 2 has level [2 1]
Posttreatment with Drug 2 has level [2 2]
As I mentioned, I entered these levels first for Factors (4 factors) and
then for cells (4 cells). However, I am getting the following error
message:
Error Message:

??? Error while evaluating uicontrol Callback.
Why the error message tells me it is 4 way full factorial? What am I
doing wrong?
I appreciate your comments.
