Is it possible to run a 2x2 ANCOVA in SPM12? Right now I have subject, group and condition factors in my model.
I keep on getting the following error when trying to add a covariate to my model:
----------
16-Jun-2019 15:34:52 - Running 'Factorial design specification'
16-Jun-2019 15:34:54 - Failed 'Factorial design specification'
Index exceeds matrix dimensions.
In file "/Applications/Neuroimaging/functional/spm12/spm_design_within_subject.m" (v4837), function "spm_design_within_subject" at line 82.
In file "/Applications/Neuroimaging/functional/spm12/config/spm_run_factorial_design.m" (v6219), function "spm_run_factorial_design" at line 515.
No executable modules, but still unresolved dependencies or incomplete module inputs.
----------
Thanks,
Jeff Browndyke
