Dear Anderson, I have been using autoaq for my resting state analyses. Looking at the results in fslview, shows that the results are localized in posterior regions. However the autoaq command shows that the results are in the frontal areas. I think this difference stems from a difference in image dimensions. In melodic I resampeled everything into 3mm. The dimensions of my dual regression images are provided below. I created an atlas that fits these dimensions (with applying FLIRT on the Harvard Oxford atlas). Unfortunately, autoaq does not provide me the correct output. I am not sure which atlas it uses or whether I can tell it to use the one that I created. Any ideas how I can solve this? Should I warp my dual regression to fit the 1mm atlas? How can I do that? Thanks!
