is there a way to omit voxels from a particular gradient, rather than omitting a voxel from *all* gradients?
i see that removing an area of artifact from the b0 nodiff mask would remove that area from all processing. but what if, of the 32 gradients, there is only 1 gradient that contains the artifact? in other words, for this voxel, use 31 gradients and drop the gradient containing the artifact.
thanks,
