Hi SPMers,
I m occuring some trouble when i run a model estimation for a one-sample t test. It happens for 2 groups separately.
This is what i get in Matlab:
Initialising parameters : ...done
Plane 46/46 , block 1/1 : ...done
Temporal non-sphericity (over voxels) : ...ReML estimation
Failed 'Model estimation'
Reference to non-existent field 'Vi'.
In file "/Applications/spm8/spm_spm.m" (v4191), function "spm_spm" at line 868.
In file "/Applications/spm8/config/spm_run_fmri_est.m" (v4022), function "spm_run_fmri_est" at line 33.
The following modules did not run:
Failed: Model estimation
On the odd part is that when i run two-sample t-test with these 2 groups involved, the model estimation runs fine.
Can anyone help me understand the error and find a way to fix it?
Thanks a lot,
