Hello to all,
I 'm seeking your help again with a flexible factorial design that gives me the following error:
Running 'Factorial design specification'
Mapping files : ...done
Design configuration : Failed 'Factorial design specification'
Error using ==> spm_meanby at 31
row dimension mismatch between inputs
In file "/Users/lauraravasi/Documents/MATLAB/spm8/spm_meanby.m" (v1143), function "spm_meanby" at line 31.
In file "/Users/lauraravasi/Documents/MATLAB/spm8/config/spm_run_factorial_design.m" (v4185), function "spm_run_factorial_design" at line 804.
The following modules did not run:
Failed: Factorial design specification
So I'm not sure where my problem comes from as my design is as follows:
10 subjects in total, 2 groups : Group 1 (n=6) and group 2 (n=4) ; Each subject has been scanned 3 times at Time 1, 2 and 3.
I would like to see the main effect of the subject and the interaction of group and time, so I wrote main effect 1 and interaction 2 3.
I have 30 scans, all with the same origin, voxel size and dimensions...
Here is the matrix that I uploaded after having selected all my scans..
Any help will be very welcome...
Regards
Laura
