Dear experts,
I am applying Greicius' goodness of fit procedure in which I compare each participant's ICA components to a standard template (ex DMN) to see which component best matches the template. My question is: The images used as components are the thresh_zstat images outputted from melodic? If yes, is the activity represented by z-values? I used fslstats to calculate the mean intensity signal of a component falling within the template ROI but I'm not sure what these intensities represent (some min intensities are negative).
Thank you in advance!
Helen
