Patricia.Thanks in advance,And then I ran randomise. I have obtained F results in FA, MD, AD and RD. There were results in t contrast for FA and RD. However, although F results were evident in MD and AD (at --thresh=0.95), i didn't find any t contrast difference (at --thresh=0.95 as there were in F analysis). Only at --thresh=0.90 or less.I proceed as following in Glm (images attached). Is the Glm construction ok?Dear Mark and FSL experts,I wanted to ensure that the construction of my Glm design is correct. I have 3 groups and i want to obtain F results (global differences) and t results (group contrasts differences).
Could you please tell me if i proceed correctly?
