Hi cat, you could alternatively use GraphVar (rfmri.org/graphvar) for this purpose. Simply enter your time courses, compute a connectivity matrix and do a group comparison with the build in statistics functions. Best, Johann
Dear Expert, I successfully used DPARSF to define 33 ROI's and to extract the ROI time courses for my subjects. I have two groups and I want to see if the connectivity within the 33 ROI differs between groups. I would be grateful if you could advise me on how to set up this analysis in the dpabi "statistical analysis toolbox'. I am not sure what files I need to input from each individual. Are these the .mat files or the .txt files? With kind regards, Cat
