Hello FSL List,
I'm running a series of contrasts, and I'm concerned that some of my results might be artifacts brought about by the fact that some of the voxels in one image are deactivated. For example, in A-B, it is possible that if some of the voxels in B are below baseline, this will make it look like those voxels are experiencing positive activation in A. What is the best way to deal with this problem?
