Dear all,
I am working on resting state fmri data as my MSc thesis. I implemented Dynamic causal modeling on fMRI data. I defined six ROIs of DMN by ICA. In DCM analysis, I defined GLM without condition duo to resting state, and I defined one T-contrast and F-contrast with value one. After definition of ROI by ICA, I specified DCM with full connectivity. I pushed estimate (timeseries) button to estimate my model. Then I optimized model and I saw two files which are DCM_BPA and DCM_opt and some diagrams. I expected to have 2^15 models in log-posterior diagram, but the number of reduced models are less than 300, in addition there are some errors in other diagram which I cannot decide which model is winner. I need urgent help and I would really appreciate it if you help me about these problems.
