Dear SPM experts,
I'm running a seed based connectivity analysis with resting state data and a pharmacological intervention.
I have thirteen subjects with four intervention doses and seven timepoints (4x7).
So for each subject I have 28 conditions. So far I have used a full factorial design. To consider Subject as a factor, I would like to run a flexible factorial design. I'm also including one covariate.
The fullfactorial model took only a few minutes on a server using matlab 2014b.
However, the flexible factorial design is running more than a week. It is still checking for temporal non-sphericity.
I'm not getting any error message. At some point matlab crashes.
Do you know what might be wrong or what i could improve?
