Hello. I am trying to perform a group analysis on eight subjects using SPM8. I am using the Specify 1st Level option. Attached are some screenshots of the analysis. I have performed this same analysis on eight separate subjects and I receive an SPM.mat. However, with the current group of eight subjects, I am receiving the following error:
Failed: fMRI model specification
I am trying to perform this analysis in order to find the activated voxels for the group.
I would appreciate any help in resolving this issue.
