Hi,
The script epi_reg is what I would recommend, so it sounds like you are doing things appropriately. If you only have 3 DWI images then I imagine that there will be a limit to how well our tools can work. Do you have a non-diffusion weighted image (b=0)? And are you trying to correct for eddy current distortions?
All the best,
Mark
