Hi Matthew,
Thanks so much for responding. It appears that the problem was with the installation of FSL. I installed it on a fresh computer and ran the analyses again and got the correct files finally! My last question regards whether or not to use FIX. Since I’m using completely preprocessed (including motion detected) files, do you think its necessary? Would you need to see the components?
Lastly, we sampled 3 mm voxels…do you know where I can find a MNI152_T1_3mm file? It doesn’t seem to be in the standard files on FSL.
Thanks much!
Pranish
