I am having trouble registering and normalizing fMRI data that was gathered using a
sequence with an RT of 1s consisting of only 14 slices centered on the OFC in four subjects.
Normally I use 44 slices to cover the whole brain and normalize my data by taking the
mean of a subject's functional scans and warping it to a EPI template. However, this
procedure is failing badly now that I only have coverage of a small area of the brain.
Registration between a subject's functional scans and T1-weighted anatomical scan is also
giving poor results. Does anyone have any advice on how to achieve usable registration
